Router DHCP and Server 2008R2 DNS

Hello all,
Netgear Genie WND4300 as DHCP Router/Server
Server 2008 R2 as DNS server (AD DS)
Q: How can I get the DNS server to update automatically from the DHPC router?
And no, I can't move the DHCP role from the router to the server. (Which is probably the best solution but.....)
Thanks in advance,
don

Hi,
Do you want to configure the DHCP server to register and update DNS A and PTR records on behalf of the DHCP-enabled clients? If yes, based on my experience, you need to configure on the DHCP server. Since your DHCP server is a router, you can contact its vendor
for the specific settings.
Best regards,
Susie

RoboForm Lite no longer works for Firefox 17 windows 7 and server 2008r2

Greetings,
RoboForm Lite no longer works for Firefox 17 windows 7 and server 2008r2 I tried to reinstall but none of the tabs function . Thank you for your assistance

'''roboform_firefox:'''
The original poster (OP) reported his/her OS as Windows 7 in the body of the question, therefore, your solution would be of no use to the OP. You can also see the OS for the system used by the OP to post the question to the right of the original question in this forum .
Additionally, using an old version of Firefox is ill-advised as old versions contain uncorrected security vulnerabilities. Roboform has been very good lately in keeping their products updated for new Firefox releases and any problems with their products should be reported to them so that they can address any issues and release an update if needed.

APs not getting IP addresses on Server 2008r2

Has anyone seen this? We had about 30 APs drop off the network after a controller upgrade and had to be manually assigned an address. We found that the APs are DHCP and have a reservation in the excluded range of the scope. In the new version of DHCP in Server 2008r2, even with a reservation in an excluded range, DHCP will not issue those addresses to clients. Deleting the reservation and letting the AP find a valid address in the range didn't work either.

Where are your APs? Are they directly connected to your 2106, or are they connected to a switch like normal?
Assuming connected to a switch, the WLC config is irrelevant to an AP getting an IP address. Whatever vlan your APs are in, they'll do a broadcast dhcp request and you'll need an ip helper-address or something to get it to your dhcp server..............
So do you see any kind of dhcp request make it to your server?
If this is directly connected APs, then perhaps someone else on the forum can share thier experience with this?

How share ADSL Internet connection to all machines without RRAS but using Windows Server DHCP and DNS

Hello!
I have this scenario on my small network with 10 PCs (connecting from outside to inside my network):
1) Modem with ADSL connection
2) Wireless Router with public IP on WAN interface
3) Switch
4) Server 2012 with DC/DHCP/DNS (with 2 NICs) and others servers/desktops machines
I want to share internet to servers and desktops.
I was able to share internet by 2 methods searching on google, but I am not satisfied with them:
First method - Using the Wireless Router and its DHCP Server
I turned on the DHCP inside the Wireless Router. All machines will get an IP and be able to go to Internet, but I don’t have the ability to control the DHCP and DNS in the router
how I would like to have, because the server DHCP and DNS must be turned off on Windows Server.
Second method - Using the Windows Server RRAS NAT, DHCP and DNS server
I have 2 NICs on the server:
NIC1 - CONNECTED TO SWITCH
IP: 192.168.1.1
MSK: 255.255.255.0
GTW:192.168.1.1
DNS:192.168.1.1
NIC2 - CONNECTED TO WIRELESS ROUTER
(the LAN IP of the wireless router is 172.16.0.1)
IP: 172.16.0.2
MSK: 255.255.0.0
GTW: 172.16.0.1
DNS: 172.16.0.1
After installing and setting the RRAS with NAT at the Server, the internet began to work on all machines but at some times the internet stop to load some
random webpages, and if you hit a couple of times the F5 button, the webpage open sometimes, but very, very slow.
I saw other people in foruns saying that RRAS is not very good, and could cause weird things at internet connection, so, now I think the internet is horrible
because of RRAS. After notice that internet is bad I tested it connecting a cable direct to the lan ports of the Wireless Router, and the internet works fast and perfect.
What is the best thing to do in my case to maintain Windows Server DHCP and DNS turned on and Internet be shared without loss of quality?
Thank you!

Hi,
please deploy according to this network topology. please turn off DHCP from router and use internal NAT function to share internet. Detailed configurations:
Router part:
LAN address: 192.168.1.1/24
DHCP part:
scope name : site name
address pool: 192.168.1.3-192.168.1.254
scope options:
router:192.168.1.1
DNS server:192.168.1.2
DNS part:
configure a forwarder to point to the public DNS address such as 8.8.8.8
with these settings, you can maintain Windows Server DHCP and DNS turned on and Internet be shared via hardware router.

Mike

DNS / DHCP Issues in Server 2008R2 Domain

Hi folks,
We’ve been having an ongoing issue for a while now in that some PCs and laptops (Win 7) in our company can’t be contacted by hostname i.e. if we try and RDP from one Windows 7 PC to another the RDP session fails as if the PC isn’t turned on, but it
is indeed turned on and connected to the network.
Even if we ping the host name of a particular computer that is on it fails to reply but if I go into DHCP I can find the hostname bit it has a different IP address assigned to it other than what is listed in DNS for that host name.
So for some reason when some computers get switched on and be allocated a new dynamic IP address through DHCP the corresponding record in DNS doesn’t seem to get updated meaning we need to go into DNS and manually amend the Host A record with the new
IP address that it has been given so we can RDP onto that computer using the hostname.
At present aging and scavenging isn’t enabled in our environment as we are afraid to in case it removes live DNS entries that just haven’t been turned on in a wee while. Does aging and scavenging just ignore static DNS entires and does aging and
scavenging work in DHCP as well?
One other thing I noticed is that if I delete an incorrect DNS Host A record and create it manually and assign the hostname and the correct IP address it says static rather than having a timestamp on it. When I create the new record I always click on our
domain in the Forward Lookup Zone and on creation I always select Create the associated pointer (PTR) record so not sure why the manual record doesn’t get a time stand.
So any help/advice or suggestions would be greatly appreciated.
Thanks,
Bonemister

Hi David,
Thanks for your reply and for clarifying those things for me. Unfortunately in my workplace when I add a manual DNS Host A record it does become a static entry and doesn't have the '0'
you mention, do you have any idea why that would be as I'm worried about it affecting things if I were to enable aging and scavenging.
Is it possible to just enable aging and have it remove entries before a time of my choosing or does scavenging need to be enabled also?
I still can't understand why the relationship between DHCP and DNS isn't working correctly. Sure if DNS has an A record for a computer and the IP address changes via DHCP there is bound to be
a way to setup DNS to be able to update the records it holds - do you know if my reading of this is correct.
By the way, I can confirm that my adapters TCP/IP DNS settings are the same on of the PCs that had the DNS fault as in your screenshot the only different is we have the tick in Append parent suffixes... - would that make a difference.
Thanks also for that other link, it seems very interesting and I'll have a good read through it carefully before doing anything!!
Thanks again for you reply and I look forward to seeing any responses.

Bonemister

Non-ISP DDNS with Apple DHCP and DNS Services

I have two questions about Dynamic DNS (DDNS) as it applies to Apple's DNS and DHCP services within my home network. I am not talking about DDNS in the context of making my external-facing router available by a domain name on the Internet using the dynamically-assigned IP from my ISP.
Starting with Snow Leopard Server, I attempted to use Apple's DNS and DHCP services (I have the firmware-based DHCP service in my router turned off.) The difficulty I immediately faced was that Apple's DHCP implementation didn't update the DNS service as IPs were handed out to DHCP clients. Because of this, it wasn't possible to access hosts by their hostname, since getting a DHCP-assigned dynamic IP at boot-up didn't do anything to automagically register the hostname-to-IP mapping in DNS. Manually registering the hostname in DNS was pointless, becuase over time the client IP address can and did change. I could create static IP assignments based on the MAC address, but doing that for all of the devices on my home network sort of defeated the purpose of using dynamic IPs.
The only solution I eventually found was to go out and get an open source DHCP server, compile it for my Mac, install it, and configure it. After doing this, everything worked great; every time a new host or other device was booted it got a dynamic IP through DHCP, and then the DHCP server automatically updated Apple's DNS serive with the hostname and assigned IP. I could immediately access every device on my network by hostname. As IP addresses changed over time, the hostname-to-IP mapping in DNS was automatically updated.
Except, Apple's point upgrades kept breaking my non-Apple DHCP install. Every time I applied software updates to my server I had to go back and re-finagle DHCP to get it to automatically start and run. By the time Lion Server came out, I drank the Kool-Aid and went back to Apple's DHCP implementation. I was disappointed that it still didn't seem able to update DNS with hostnames as it assigned IPs, but I was so tired of mucking about at the command prompt to fix DHCP every time Software Updates broke it, I just lived with the inconvenience of not being able to access devices on my network by hostname.
I'm sorry to say this, but Windows Server has had this capability since at least server 2003. In fact, until I dumped my Windows Server and switched to Snow Leopard Server, I was running Microsoft's DNS and DHCP services on Server 2003 and they did exactly what I'm describing brilliantly.
Can anyone offer any advice here? Does Mountain Lion's implementation of DHCP allow for DDNS updates to the DNS service? If not, how are other people handling this? Should I go back to running Windows Server for my DNS and DHCP services? My Netgear WNDR3700 router appears to have the standard, substandard DHCP server in firmware as most home routers, and no facility for DNS at all--much less the ability to update an on-site DNS sever with IP addresess it hands out. In fact, the only appliance I know of that does this is the InfoBlox my employer uses, but that's too expensive for a home solution.
As a Post Script, I'll add that I've been VERY unhappy that I lost the ability to bind Windows clients to Open Directory under Lion Server. Since I'm starting to see articles that say this capability hasn't been added back to Mountain Lion Server, I'm seriously considering implementing a Windows Server AD master and establishing a "magic triangle" or "golden triangle". If I end up having to do that, I wonder if I might as well just go back to using Microsoft's DNS and DHCP services.

Hi,
Whether to move your DHCP to another server depends on the workload of your server. If there are too many clients on the network, you should move your DHCP to another server.
Did the record which owned by the machine generate before you configure the DnsUpdateProxy group? You can try to regenerate the record and check the result.
For more detailed information, you can view the link below.

DNS FQDN Mavericks 1.9.0 and Server 3.0.1

Hello everyone.
I’m tstill on my Maverick test server and I can’t get my DNS right. Please help.
Mavericks 10.9.0 on Server 3.0.1 on 1 MBPro 2011
Mavericks 10.9.0 Client on 2 MacBook Air 2011
Lets say I registered example.com with easydns registrar.
My registrar points to my dynamic IP which only changes only every 8 to 12 months.
Everything look pointed right from my registrar as I hosted test servers many times before.
Coming into the house, I have a 2Wire 2701HG-S Gateway DSL 1.5 Mb/s Modem that does DHCP, NAT and port forwarding * But it does not do any DNS or provide FQDN forward or reverse.
All it does is allocate IPs and slips the ISP search domain and it’s own address for DNS.
I tried with a Linksys WRV201 which only supports DynDNS or TZO
So, for the moment, I guess. I’m cornered.
1- Do I read correctly that as long as I do not have another machine (Linux, Window, Older Mac server or special router) on my Intranet that does DNS of Mavericks’s FQDN forward and reverse, It is useless for me to even install Server 3.0.1 on Mavericks?
2- Once Mavericks is all installed and self pointing and clients configured to look it up, Can I get rid of the other server that would be just there to FQDN Mavericks server?
3- Can I just take one of my MacBook Air clients, give it a static IP, activate bing and it acts like a DNS server the time that I Get Mavericks server up?

Relevant to your gateway device (whatever's at the edge and performing NAT for you), but largely irrelevent to your server and the rest of your local network.

What's happening with dynamic DNS and the rest is all outside your network perimeter, and largely irrelevent to anything other than remotely accessing your network.

Your local DNS is the DNS service on your network, and Mavericks Server (and most other servers these days) expects functional local DNS, and most servers (including Mavericks Server) can be configured to provide local DNS, as can some mid-grade firewalls.
No ISP and no dynamic DNS provider can get you local IP address to domain (host) name translations.
Name to address is what everybody's familiar with, but address to name is the basis for SMTP mail spam checks (on the open internet) as well as certificate security and related processing; of user and host authentication.

Your local network has a local address space, and your Mavericks Server can and usually should have its own domain name in a domain you've registered, or a subdomain of a domain that you've registered, and not in a domain that's registered by your dynamic DNS provider. It's possible to use a bogus domain, but thousands of new top-level domains are coming online. (OS X will not react well to finding its IP addresses differ from the public translation, and you probably don't want to have to mirror all of the dynamic DNS provider DNS locally.)

Mavericks Server will install and boot with local DNS running, if you don't (incorrectly) tell it to use off-LAN DNS, such as that at a dynamic provider or at your ISP. (Neither of which provide translations for a NAT'd network, hence mismatched names or changing names or other oddities, hence server confusion.) You'll get a one-host zone with whatever domain you've chosen, with the local IP address as the translation.
First step after the Mavericks Install (and preferably after registering a domain for your internal use) is configuring DNS on Mavericks Server for your new server and your new domain, setting up static addresses and names for network printers and the internal IP address of your gateway and other such, and assigning the Mavericks Server DNS server IP address to your DHCP server as the DNS server address to vend to clients.
Here's a write-up on the confusion that can arise around dynamic DNS. Dynamic DNS is good for remote access into your network when you've only got a dynamic IP address but — whether due to other DNS-related issues or ISP port blocks and blacklists that are common with the dynamic IP tier of service, you may eventually graduate to using static IP. Dynamic IP is good for remote connections into your network, but not so good when you're connecting out for SMTP mail or other services.
FWIW, while you're setting up the network, get out of 192.168.0.0/24 and 192.168.1.0/24, as — if you ever decide you want to VPN into your network — the VPN server will have issues. These subnets are used all over the 'net, and VPNs are based on IP routing, and IP routing doesn't work well when the same subnet is on both ends of the connection. There are other subnets in 192.168.0.0/16, and there are two other available private address blocks to use. Changing the IP subnet block is feasible at any time, but the more entrenched the references to the subnet become within your environment, the more effort is required to change it. Better to get out of the way of any potential VPN usage earlier, rather than later.

OS X Server, Internal DNS and Apple Airport Extreme

OK,
There must be a way to do this. I cannot believe that this simplist of functions to a Wireless Router would have been missed off the new range of Airport devices.
I have an OS X Server, serving DNS internally and forwarding lookups to the Airport which forwards on externally.
Trouble is I want the Airport to connect to PPPoE and serve the guest network with DHCP and DNS but let my server do DNS on the internal network.
Why is there not a simple box in setup utility that says "use this DNS server on the local DHCP network" or something a long theose lines. It seems mad that Apple have overlooked this, I can only say I am missing something.
I have tried setting up a small range and putting in reservations but this limits your guest network to the same limited range so you end up with only room for two or three guests, this solution won't work for me.
It seems stupid to put the ApE into Bridge mode as I can then not have a guest network and I shouldn't have to have two boxes to acheive what I am looking for.
Rant over, any other help or solutions appreciated.
Regards to all
TMA.HA

@MrHoffman
Agreed, the Guest network will not have access to the local range. I missed that part.
In my setup, the second DNS is google server because i don't want the internet to stop working if the local server is not operational, this way at least Internet will be available.
- Client contacts Primary DNS, If it fails to reach it, it will go to the secondary. Well, to be more accurate, the OS will choose the fastest DNS server it can reach first. Ideally that would be the local server.
In a normal day when everyting is up and running:
- Client contacts the Primary DNS (OSX Server DNS), if the query is a local DNS record , it will serve the IP.
- If the query is not a local record, it will send it to the forwarder DNS server defined in the DNS service (ISP DNS or Google DNS)
For the guest network, It would be worth checking to do the following:
- Add a second Wifi network interface on the server and connect it to the guest network IP address.
- On the AirPort Extreme, put the Guest network IP address of the OSX Server in the secondary DNS field.
In this case the guest clients will always try to reach the local network DNS first and then failover to the guest network IP of the DNS server.
@piperspace
Well, a home router is already working as a local DNS server that tries to resolve locally then forwards to an external DNS server when it cannot resolve the name.
Primary and secondary in an enterprise space will surely be a main and a backup and both contain the same name spaces. But the point here was about home use and therefore the purpose will be a backup DNS server for the internet at least.

Bootpd, DHCP and OS X Server 2.2

I have a Mac Mini running OS X Server in Mountain Lion that I use for imaging via DeployStudio. A couple of days ago, I tried to boot a MacbookPro using Netboot by going to Start-up Disks, and selecting the Netboot image. When the machine restarted, it just sat at the grey screen for about a minute, then it started flashing the globe icon, as it was trying to find the Mini. After about a minute of that, it would give up and then boot back to the OS. I tried this with a NetInstall image, another NetBoot image, another machine, and so on. All of them had the same behavior.
After going through some logs and looking at the documentation, it turned out that the machines really couldn't find the Mini to boot from. Basically, if the DHCP service wasn't turned on, and configured for the same subnet that the Mini was on, then nothing could find the Mini to boot from it. This was bad, really bad, as l work for a large achadimc instatution where they run their own DHCP services for all of the subnets.
The issue turnes out to be that as of 2.2 of OS X Xerver, that the bootpd service doesn't launch by itself anymore. The DHCP service must be running for bootpd to launch. Netboot needs bootpd for the clients to find the host. The solution that I came up with was to modify the /etc/bootpd.plist file.
There are, as of when I am writting this, two versions of Netboot. Netboot 1, or old Netboot, allows the bootpd service to run without DHCP, and Netboot 2 that requires DHCP to be on for bootdp to launch. I went into the /etc/bootpd.plist file and added the following lines to the bottom, just before the closing </dict> tag:
<key>old_netboot_enabled</key>
<array>
<string>en0</string>
</array>
This turns on the old netboot so bootpd could run on its own. You'll have to restart the machine running OS X Server for the change to take affect.
There a couple of downsides to this method. One is if you turn on Internet Sharing in the Sharing system pane, or if you happen to turn on or change the DHCP settings in any way, your changes will be wipped out.
I hope this helps somebody out that that had the same issues that I had.

Hi Micah,
I have try your solution but it doesn't work.
First Excuse me for my english writing 'cause I'm french...
So the problem is complex, here is my Situation :
Netboot Server : A brand new mac mini server with 10.8.2 server (late 2012, macmini 6,2), 2 terabyte hard drives of each and DeployStudioServer 1.5.16
The services Netinstall, OpenDirectory (master mode) and AFP file sharing are all ok !
I have an external DHCP (linux) server. The DHCP server is on a vlan and the netboot server and netboot clients are on another clan, so I have
add ip address of my netboot server as a ip-helper address in the cisco router configuration of the dhcp server vlan.
And HERE IS MY PROBLEM :
I have used three kinds of netboot's client :
1. a macbook pro 17" (macbookpro 5,2, 17" early 2009) with mac os 10.6.8
2. a macbook pro 13" (macbookPro 9,2 13" mid 2012) with mac os 10.8.2
3. a Mac mini late 2012 ( macmini 6,1) with mac os 10.8.2
I have generate 2 DeployStudio Netboot sets, one for the macbook pro 13 " (10.8.2) and one for the mac mini late 2012 (10.8.2)
SO, It works without problem when I netboot with macbook pro 17" which use for example the netboot set of macboo pro 13" but the other machines don't net boot ! Why ???
In the netinstall logs and when I netboot with macbook pro 17 under 10.6.8, I saw the lines :
b 18 08:43:23 [my-netboot-server] bootpd[2825]: BSDP DISCOVER [en0] 1,0:26:4a:c:d1:8 NetBoot002 arch=i386 sysid=MacBookPro5,2

Feb 18 09:02:08 [my-netboot-server] bootpd[2968]: service time 0.000015 seconds
PLEASE HELP ME, I DON'T UNDERSTAND WHY IT WORKS WITH A "10.6.8" OLD CLIENT AND NOT WITH MY NEW MACS UNDER MOUNTAIN LION ?
HAVE YOU ANY IDEA ?
THANKS IN ADVANCE TO ALL FOR YOUR HELP
BEST REGARDS

Guest Public Network behind 10.4 Server running DHCP and NAT

I am wondering if it is possible to use APE's guest networking capabilities while still using OS 10.4 server and my DHCP and NAT servers? Is there a way to set the Airport to run its own DHCP NAT and have everything routed correctly?
Or do I still need to use two separate Airports in order to have a public and private network at my home.

I figured it out. I just deiced to run a double NAT configuration

Sles dns and dhcp; OR NOWS SBE dns and dhcp

Ok, I'm finally to the state of setting up dns and dhcp. From what I read the NOWS way is to set it up in the sbsadmin web interface. That seems to use different backend programs than the sles dns and dhcp programs. For instance I think I read that the NOWS uses dhcpd, whereas in yast it says it uses dhcp-server.
SHOULD I use the NOWS way, or the SLES way for dns and dhcp? Looks like the sles way is more easily configured and managed, but I don't know if it will not be functional for my NOWS users.

NOWS SBE doesn't provide a capability to manage DNS/DHCP other than by editing the config files. I would be much more comfortable doing what you are doing however you have to be careful. NOWS SBE sometimes installs modified OES components (or used to) so one never knows what to expect when deviating from a standard NOWS SBE install.

Setting up DNS on Xserve when DHCP and Nat ae controlled by windows machine

Trying to set up an Intel based Xserve on an internal network to have 6 other G5's authenticate to. But I am having problems setting up DNS.
This server is being added to a windows network that has DHCP and NAT handled by a different windows machine. I have also assigned the xserve with a static IP address of 192.168.1.XXX Now this server is just going to run a few programs for the 6 macs in the art department. Software Update, Version Cue, Suitcase Server. I have version cue and suitcase server up and running. But I would also like to have the macs authenticate to the server for the updates.
If I type in hostname at terminal I get:
localhost.xserve
and when I type in host 192.168.1.XXX
I get some error about no name aviable or something...
How can I setup simple dns just for the server? Would there be any down falls for having DNS setup on this machine when it is conected to a windowws network?
Please help. Sorry for the long winded explination.

Yes, it's possible. Although I'm no longer favorable towards fake "domains" like .lan or the like.
Besides which (and most people don't know) ".lan" is actually an existant TLD. So it's not so great either.
Set the server to what it's FQDN should be, and set it to answer to & for itself only.
Is everything else internally using ".lan" ? If not you're going to have to point clients to your server strictly by IP alone and while that's fine, this setup is starting to sound just ugly, if not somewhat Frankenstein-ian
But to limit requests you'll have to edit /etc/named.conf by hand.
Google can lead you to the information, there's plenty out there - here's one for example:

Having issues configuring DHCP and with Redundant router

Hello everyone
I am new to Cisco and I am having few problems in configuring my topology in Packet tracer.
I am having redundancy in router and swithes both,
I have assigned one layer2 2960 switch as a VTP server and asssigned VLANs from that switch then assigned ports to the hosts in access layer switches.
Problem 1: If I take my Router1 off I am unable to ping so the pupose of having redundant router does not serve the pupose.
Problem 2 : I need to assign DHCP server for the users who will be connecting wirelessly with Access Points, so can I configure DHCP on Access Points which I am unable to do so in Packet tracer any idea how? / Or shall I configure the DHCP on Router1 and Router2 and exclude the addresses I have assigned to all the hosts connected using ethernet.
Also how can I configure Email server in this tolpolgy and where?
Thank you

Hi Asif, Jeff is right.
(1) You need to configure either HSRP (Hot standby routing protocol) or VRRP (Wirtual routing redundancy protocol), or GLBP (Gateway load balancing protocol).
With either of this config, you will be able to configure 1 logical IP address, which will act as a gateway on your computers. However, both routers will need different IP's (all within the same subnet). You will also need to create multiple HSRP groups to support all your VLAN's. So one HSRP group per VLAN. The logical IP in the HSRP group will act as the default gateway on computers within the VLAN.
Though I don't think packet tracer supports any of the above configs - FYI it's part of the CCNP Switch sylabus. So the above explaination will make sense after you've got a good understanding of HSRP, VRRP and/or GLBP.
(2) I would recommend setting both the Router as a DHCP server, and configure the Access Point (AP) with a static IP (disable NAT and DHCP on the AP)
(3) In packet tracer, choose the Server icon and check it's properties. You should find an option to enable EMAIL server. Connect it to any of the Distribution layer switches.
Hope this helps get you started on the learning curve :-)

What are the correct mail account settings and more importantly the correct DNS settings
Thank you for any help you may be able to provide

Do not delete the old account yet. sign up for an iCloud account if you haven't.
I understand .mac mail will still come through. Do not delete the old account yet.
You cannot use .mac or MobileMe as type of Account, you have to choose IMAP when setting up, otherwise Mail is hard coded to change imap.mail.me.com to mail.me.com & smtp.mail.me.com to smtp.me.com, no matter what you try to enter.
iCloud Mail setup, do not choose .mac or MobileMe as type, but choose IMAP...
On second step where it asks "Description", it has to be a unique name, but you can still use your email address.
IMAP (Incoming Mail Server) information:
          •          Server name: imap.mail.me.com
          •          SSL Required: Yes
          •          Port: 993
          •          Username: [email protected] (use your @me.com address from your iCloud account)
          •          Password: Your iCloud password
SMTP (outgoing mail server) information:
          •          Server name: smtp.mail.me.com
          •          SSL Required: Yes
          •          Port: 587
          •          SMTP Authentication Required: Yes
          •          Username: [email protected] (use your @me.com address from your iCloud account)
          •          Password: Your iCloud password
Also, you must upgrade your password to meet the new criteria: 8 characters, including upper and lower case and numbers. If you have an older password that does not meet these criteria, when you try to setup mail on your mac, using all of the IMAP criteria listed above, it will still give a server error message. Go to   http://appleid.apple.com         then follow directions to change your password, then go back to setting up your mail using the IMAP instructions above.

Server 2008R2 mapping to shared folders fails users of Windows 8.1 but seems OK on Windos 8.0 and no problems for Windows 7

Having read what I could from the related questions, the answers still elude me. This issue apparently is specific to Windows 8.1.
First, a little background.
1: The server is not on a domain, The system runs Server 2008-R2 standard with all folders shared across a standard "Workgroup" type network. They would prefer to
leave this layout intact.
2: The shared folders are nothing but Data files. There are no active system folders or anything used in an "active" environment. They are mostly Word doc, excel
files, pdf, txt, etc. However, due to the requirements of the software that needs to access these files, they Must
reside on a mapped network drive letter. Nothing else works due to the way the SQL database program stores the reference points back to the data.
I have had some success using what amounts to a “simulated” mapping using WebDAV to access the server. But access speed is a lot slower ad file size is limited.
3: The system has been configured as-is for the past 3 years with Users all on Windows 7 x64 (mixed OS, some Home Premium, some Professional) and the only problems that come up are when
access is through an ISP that blocks port 445. This was the original reason for finding a WebDAV/Cloud method just for those Users since they were unable to Map drives to anything on the Office Servers from their Home Internet even when using a VPN.
When Windows 8.0 became the only version available, I added a few users whose new laptops came with 8.0 from the vendors. While there were a very few minor problems, for all practical
purposes, I was still able to provide access to the mapped folders.
As the Windows 8.1 roll-out progressed, some users were successfully upgraded while others are still stuck in Windows 8.0. The issues with this seem to be hardware related and vary
depending on the Make and model of the laptop. I have been assured that eventually all of these will be able to advance to 8.1. But this delay has given me an excellent mixed OS environment for testing.
On the users who have not yet purchased new equipment and who are still using Windows 7. There has been no change. Their drive mapping is stable and they can always connect as usual.
Those blocked from lack of port 445 or still blocked. Systems inside the Office and those with ISP's who allow port 445 can use all mapped drives as normal.
Users who had Windows 8.0 and who have not yet been able to upgrade to 8.1 also have been unaffected. Same results as Windows 7.
Users who got the Windows 8.1 upgrade as well as those that came factory loaded with Windows 8.1 seem to be a never-ending list of problems. The ones that came native with 8.1 are worst
of all. The list of error codes runs through everything that has to do with “communication with the server”. As far as I have seen, this appears to be the issue.
Whether they are in the office on a wired network connection or at home on a Wi-Fi connection, the issues have the same results but the actual error codes may vary slightly. All of
them refer back to an inability to communicate with the server.
Nothing on the server has changed in any way. Users with Windows 7 continue to have zero problems, Users with Windows 8.0 seem to be doing fine as well. Only those with Windows
8.1 are affected and their problems are dramatic with everything from a total loss of drive mapping to misdirected data when the maps are active.
I have tried to make the drives automatically remap on reboot. I have tried registry modifications. I have done everything I can think of to make a difference but the results are the same
for every system using 8.1. The mapped drive letters invariably disappear. Sometimes while the system is in use ( I think I have been able to trace this to times when the system enters Sleep or Hibernate) but always when the system reboots.
One detail that might point to somewhere is that the "time to connect" when mapping the drive is so long that I believe some of the original failures were due to not waiting for a
minimum of 3 or 4 minutes to give time for the Shares to show-up in order to map them. Once the mapping is successful, the file access speed seems normal. But invariably, the drive becomes "unmapped" repeatedly each day.
I know this was a long question but I have tried to provide every possible detail for anyone who has experienced events like this who may already have a solution. I would even be glad
to purchase a 3rd party application if that is what it takes to get this to work. My next planned effort is to try using Server 2013 but I am afraid that might open another can of worms for those who still use Windows 7.
I have also been told that this is in some way related to the push to "Cloud" support in Windows 8.1 OS but I do not see where this would come in. I can say that this was the
one place where things continued to work as before. People who had Windows 8.1 and who had to use the CLOUD copies of our data are still able to connect to it with no problems.
Any suggestions appreciated. Preferably those that would not need extensive changes to the basic network structure. This "workgroup" consists of less than 25 users and any
extreme measures would be hard to justify

Hi，
I sugget you try to ping server so that we can verify the connectivity.
Can windows 8.1 access Windows Server 2008R2?
Also,please check the event viewer to see if some error log appeared when the issue occurred.
