Access Connections fails to recognize DNS server for wired Ethernet connections

I'm running Windows 7 on a Thinkpad T410i. I ran the Lenovo update yesterday which updated Access Connections from 6.01 to 6.21. I then could not make any network connections to the Internet. I used Windows System Restore to back out the changes made by the Lenovo updater.
Since then, I am able to connect to the Internet using the wireless adapter, but the wired LAN connection fails to connect to the Internet because it doesn't recognize the DNS servers The wired LAN adapter is the Intel 82577LM Gigabit Network Connection. The IP v4 configuration settings haven't changed (use DHCP, obtain IP and DNS addresses automatically), but it can't seem to connect to the DNS servers.
The message from Windows Network Diagnostics is:
Your computer appears to be correctly configured, but the device or resource (DNS server) is not responding.
The symptoms appear the same as in this problem in the Lenovo support library, but that was occuring with Access Connections 2.60, a much earlier version of the software:
Network connection is not working if Access Connection is used to set DNS information - ThinkPad General
Symptom
When a wired (Ethernet or Token Ring), network profile is created with Access Connections v2.60, the user may be unable to connect to a LAN or the Internet.
Affected configurations
Any model ThinkPad system using Access Connections v2.60
Does anyone have any suggestions? Thanks!

Help needed with printer settings for wired ethernet connection

I'm hoping someone can help me with a network printing issue. I have a large format color laser printer (Tektronix Phaser) and since moving to OS 10.6 I can't figure out how to configure the printer so that the system sees it. I have a simple wired ethernet network with a couple of Macs and a couple of printers. All devices are connected via a switch. When using earlier OSs I was able to connect to the Phaser using Ethertalk. Obviously this is no longer supported and I can't figure out how to set the printer so the OS can see it. I have lots of options which can be turned on or off and in some cases set up in other ways: Ethertalk, IPX, Netware, TCP/IP, DNS, LPR, HTTP and remote internet printing, I've tried messing with these but the result is always the same--system doesn't see the printer. Currently Ethertalk is on, IPX and Netware are off, TCP/IP is on, DNS and LPR are on, as are AppSocket, HTTP, FTP and remote internet printing. I can change the IP address but no matter what address I've tried I cannot ping the printer. (I'm using a Gutenprint driver for this printer.)
I don't really know enough about all this to get anywhere and I haven't been able to find help anywhere even from tech friends. Xerox won't help me and neither will Apple. Any help would be appreciated. I can supply more detail on specifics where necessary. Thanks, Bob

Old Phaser models may becoming more and more difficult to use, but you can give this a try.
1. Configure the printer via front panel to use TCP/IP and enable DHCP if it's supported. If not then you will need to configure an IP address for the printer together with your local network's mask, and gateway IP address. Except for the first the others will be provided by opening Network preferences to see what those settings are. The printer's IP address needs to be set somewhere within the range of IP addresses your router provides locally.
2. You need the PPD file required for your printer. If you have the Phaser driver installer you can use it to install the PPD or you can extract the specific PPD from the installer package. This part is tricky because I don't know where you may find the driver now if you don't have the installer. The older installers can be accessed through the Finder by selecting the package then CTRL- or RIGHT-click and select Show Package Contents from the contextual menu. You can then rummage through the package to search for the PPD for your printer. Then navigate to the /Library/Printers/PPD/Contents/Resources/ folder and drop the PPD file inside.
3. Open Print & Fax preferences and click on Add [+] to add a new printer. Click on the IP icon in the toolbar. Select Line Printer Daemon - LPD from the Protocol drop down menu. Input the IP address you assigned the printer in the Address field. You can file in the optional fields that follow. Then from the Print Using drop down menu locate the listing for your printer and select it.

Want to bridge two wired ethernet connections

I have a Core Duo based Mini that was just replaced with a new aluminum MacBook. I am going to re-purpose the mini as a media center device. I already have a TiVo HD unit hooked up to the same TV. The TiVo is hooked up through a wired ethernet connection, to better support streaming and the transfer large video files. Due to the visibility of the location, I would prefer not to place a hub there, and I would prefer to avoid having an extra power cord around for a hub.
I'm considering getting a USB ethernet device. Then I can connect the TiVo box to the internal ethernet port (en0) and connect the usb ethernet port (en1?) to the remainder of the network. I would then bridge the connections. Note that routing is probably not sufficient, because the other TiVo units would not detect the one on the different network. I need a bridge, which would allow all the TiVo units, including the one behind the Mini, to be on the same network and discover each other via broadcasts.
This is normally a fairly trivial thing to set up within a unix environment. I can find tons on information on how to do it in Linux. But I cannot find any info on doing this within Mac OS X.
Also, where can I find information on USB ethernet devices supported within OS X?

GdayBruce,
Even though you don't mention it, I am assuming that somewhere in this gordian mix you have a router. Beyond that, I cannot fathom what it is you are trying to do here. You may be making things way more complicated than they need be.
I think I get that you want to connect the Mini to the network (what network, though, and created by what device??? How many "networks" are there, and what are their purposes?), then connect the one and only TiVo unit you mention to the Mini, using the Mini as a "bridge."
OK, let's just start this whole thing over. You need a router. Full Stop. One router. Full Stop. That router will be connected, no doubt, to some type of modem (cable or DSL) of course, and everything else will connect to it, either wirelessly or via ethernet. One router, one network.
Now, one way to avoid having to route cables all over the place in order to connect devices via ethernet is to create a wireless network and use additional wireless devices as "bridges." THese devices would be configured to connect to the wireless network, then provide a wired ethernet connection to that wireless network. In other words, they "bridge" the two. Older Airport Express units could bridge ethernet to wireless, but no the other way around. I'm not sure if the current AEs can bridge wireless to ethernet (they might, but I'm not sure).

GSS as primary DNS Server for Intranet

Hi,
Can the GSS be used as a as primary DNS server for Intranet? An additional DNS server can be configured to answer the unknown Records like MX by GSS.
if it can be configured, I would be thankful if anyone shares with me the brief configuration steps Apart from configuring Answers, answer groups, domain lists, source address lists, DNS rules.
with thanks
sathappan

Yeah I'd certainly recommend against it! So essentially the client machines are unable to update or query dynamic AD related DNS records since they're not pointing to the DNS servers actually used by your AD server(s). I could well imagine that causing
issues, and meaning that some AD functionality won't work correctly.
I know you can directly integrate BIND with AD, eg so that the BIND servers are the ones used by AD, though I haven't tried it, but this seems to be neither.
I can't find any articles relating to your exact situation, presumably no one else has tried to use such a mixed and disjoined setup. I'd focus on looking for articles relating to why you shouldn't point your users at a router (most commonly in small setups
on ADSL) for the DNS rather than directing them to the server for DNS and then having that query the router for external results. It's a more common scenario and you're more likely to find articles relating to it.
One article you might find useful is
http://msmvps.com/blogs/acefekay/archive/2009/08/17/ad-and-its-reliance-on-dns.aspx which talks in terms of using your ISP's DNS servers on the client machines, but in your situation it sounds like the BIND servers are essentially providing an equivalent
setup.
There's also various discussions and comments on the topic elsewhere on these forums, for instance
http://social.technet.microsoft.com/Forums/windowsserver/en-US/c3ba3859-765e-4b3f-add0-eaf2c18e1068/i-have-dns-in-a-router-and-i-want-to-install-domain-controller?forum=winservergen and

Dns server for specific domain

Is there a way to define a dns server for a specific domain?
I'm setting up a develop machine with an amp stack and i want to redirect all urls with a specific domain (i.e. project.dev) to 127.0.0.1.
I've done this on OSX with dnsmasq configured in this way:
# dnsmasq.conf
address=/.dev/127.0.0.1
listen-address=127.0.0.1
port=35353
and adding a dev file in /etc/resolver with this content
# /etc/resolver/dev
nameserver 127.0.0.1
port 35353
but this in arclinux with dhcpd doesn't work.
I've tested dnsmasq with
dig [email protected] -p 35353
and it works (the address returned is 127.0.0.1) so the problem is the resolver.
I've also tried either put into /etc/resov.conf.head this:
# /etc/resolv.conf.head
nameserver 127.0.0.1
port 35353
and configure dnsmasq with the default 53 port without luck.
This is my /etc/resolv.conf
# /etc/resolv.conf
nameserver 127.0.0.1
nameserver 192.168.0.1

On linux you should simply run all dns request through one nameserver that forwards everything it doesn't understand. [Edit: You can do that with dnsmasq.] Another simple way to create a local developer zone would be to use wildcard_dns_proxy instead.

If you bring up Safari browser, and go to www.google.com, does it give you an error?
It is possible that you are not getting DNS. From the OSX terminal can you run the following two commands

Is there a way to turn the wireless capabilities off on an AirPort Express? I have an AirPort Extreme as my main router and use the express to just extend it. I only really want to you use the express for hard ethernet connections

Is there a way to turn the wireless capabilities off on an AirPort Express? I have an AirPort Extreme as my main router and use the express to just extend it. I only really want to you use the express for hard ethernet connections. For whatever reason when I have my express extend my wifi at home the download speed from just the express is absolutely terrible, drops to about 1.5 mb compared to when it's on the extremes part of the network the speed goes up to 50-75mb. These terrible download speed really only affects the iPhones as my MacBook Pro usually gets the good speed no matter where it is. I don't believe there is anything wrong with my phone because if I am in the part of the house that uses just the extreme the download speeds on the iphone goes up to 50-75mb. As a note I have an AirPort Extreme on the top floor of my house (second floor) that's where my modem is located. On the first floor that's where one airport express is located. I also have another airport express in the basement that is accessed by my landlord. Any thoughts on how to fix this would be helpful.

It appears that your networking goals with the AirPort Express is to use it as a wireless Ethernet bridge instead of using it to extend the wireless range of your AirPort Extreme. The latter requires that the Express Wi-Fi radios be enabled.
If you intended to use the Express as a wireless bridge, you just need to reconfigure it to "Join a wireless" network instead of "Extend a wireless network."
For whatever reason when I have my express extend my wifi at home the download speed from just the express is absolutely terrible, drops to about 1.5 mb compared to when it's on the extremes part of the network the speed goes up to 50-75mb.
In an extended network, the placement of the extending base station is critical as it can only extend the wireless network at the bandwidth at which it receives it.
Please check out the following AirPort User Tip for details on optimal base station placement.

HT4628 After installing the new OS from apple (10.8.2) my macbook pro keeps disconnecting from the internet. I am connecting with an Airport Extreme and while it shows I am connected, every 20-45 seconds its searching for a wireless connection. Any sugg

I guess I posted my question as a title but that is my issue. My airport is connected via wireless yet it keeps searching for a wireless connection, hence I am experiencing bad latency and disconnection issues. Anyone know a solution?

I have the same problem. And in my case it happens when i transfer "large" files over the WiFi. When i send an MP3 filer over Skype i loose connection. When i transfer updates between my iPhone 5 / iPad 3 and iMac with Mountain Lion i loose connection. When i have a video conference i loose connection. You get the idea.
There is usually like 30 people using their own router on the 2.4 GHz band near by. None on the 5 GHz band which i use. But when my WiFi freezes on ML i can only see my own router. And i am also connected to it. But all my neighbors WiFi routers are now invisble to me. My network stalled.
What i do is that i disconnect my WiFi and then reconnect it again. Thank fixes it. But all my transfers and what not has been dropped. And i have to start all over - and the WiFi will stall again.
While my WiFi is frozen on the iMac with ML i have no problem using the same router on the same 5 GHz band with my iPhone 5 or iPad 3.
Downgrading the AirPort Extreme to 7.6.1 from 7.6.3 helped a bit. Now i only loose connection a few times each day.
It is a software error in ML i am sure of. A driver maybe. But i am suspecting that it is either a speed-sync error or an energy saving error. Like the network card turns of in the middle of a file transfer to save enrgy - maybe.
When i stream movies from my iMac to my Apple TV or 3 there is no problem at all. It is so odd.

Mac-mini looses wired ethernet connection

Hey out there.
I know this topic has been covered, however i could not find a solution that works for me.
Last week I bought a intel mac-mini and got home and happily connected it to my wireless router (this all went fine)
I am using a Asus wl500g router.
However, once i updated all the software via the wirless and moved my router closer to my mac-mini.( i am using a 1 meter Cable) it tell's me that my etherent cable is not connected.
So I swapped out my ethernet cable with the one connected to my NAS which is connected to the same router and it is still did not work, Even though it functions fine on my NAS which also had two gigabit ports.
After messing with the setting on my ethernet connection i disabled IP ver 6 and did a renew and all of sudden i had wired ethernet connection.
So i thought that i fixed it. However after the next reboot, the wired connection did not connect again and it continued to tell me that there was not cable attached. I used the same cable connected to the mini to test on my macbook (also intel) and it worked just fine. I also tried swapping the cables from my mac mini and my nas again. My nas device connected with the cable that did not work for the mac and ofcourse my mac told me that i have no cable attached.
I then tried to put my mac to sleep and woke it up again and bam.. i had wired ethernet!
Great, however after another reboot, i have not been able to get connection again or since. this has been for a few days now.
SO what i know is this:
The cables are the right length.
The cabels work!
it should have nothing to do with the fact that my router is 100baseT cause my nas connects to it just fine which as i said also has two gigibit ports.
THe issue is on the mac side that is forsure!
I took my mac back to the store where i bought it and they tested it and they said that is fine, they must be connecting to some airport.
So, could some please tell me what i need to do to get a constant connection between my mac-mini and my router please.
there must be a way of getting it work as it works on and off at random times.
I have been a happy mac user for a few years, so this kind of issue is really puzzling, why does it not just work like most other things MAC?
Buying a airpot extreme is not an option in my books, as the rest of the my mac network functions just fine on my current router.
Looking forward to some inlightenment.
thanks
Dino

Hallo dinodam,
I am having exactly the same problems you are. Everything worked fine for a few months and now I copy you problem identically. Again, the shop in Frankfurt says everything works fine. All my other PCs and cables work.
I have been quietly going around the bend. Every now and again I have a connection for a short while and then it is gone. "Kabel nicht verbunden".
This tends to suggest that the problem lies either in the OS or the hardware, nothing external. Surely someone at Apple must be aware that there is an issue? The time I have wasted on this issue more than covers the cost of buying a new pc. Unless someone has any bright ideas, that is what I shall end up doing and send Apple the macmini back.
I should be grateful for any suggestions how to resolve this.
Thanks,
dilystagi

Is there a way to connect an iPhone to a wired ethernet network?
Thank you.

Thank everyone for their help.
As I mentioned before, sometimes clarity is missing.
I realize that there are no "Apple Networks". What I should have asked was "Will an Airport Extreme when connected to a non-Apple modem/router provide a wireless signal that can be used by my iPhone" - and my MacBook Pro, and my ...
There are literally hundreds of posts both here and on other Apple Discussion boards that warn/advise against using a Cisco/Linksys/Belkin/Buffalo/whatever product in the network chain (wired or wireless) with Apple products.
I am not attempting to say whether these concerns/difficulties are valid or due to a lack of experience. I am just asking, and appreciative of the response that "YES" an Airport Extreme connected via a CAT 5 cable to an old Linksys switch will work.
As someone who has suffered/struggled for years with network problems I understand the pain.
And for those of you old enough to remember --
Thankfully I did not ask "Can I connect my Iphone to the Orange Micro SCSI card on my Motorola Starmax 5000"
Thanks again to all who helped.
I've ordered an Apple Extreme and will have it surgically implanted in my excessive adipose tissue with a tattoo reminding everyone that before I have an MRI, and take off my watch and my wedding ring, that maybe someone on the medical staff should take a look at their WiFi reception.

What is your wired ethernet connection speed during Time Machine backup

I am curious as to what transfer speeds everyone is getting with a wired ethernet connection. The problem I have is I am trying to use Time Capsule as my Time Machine storage. However, even with a Cat6 cable my average transfer rate is between 250 and 300kb/s. Once in a while that rate rockets up to 16mb/s but that burst only lasts a few seconds. At this rate I am backing up about 1GB an hour. This is going to take me 7 days just to do my initial backup which is nuts. Something has to be wrong with this thing. It just can't seem to sustain a decent transfer speed.

When connected by ethernet to my iMac, I checked the transfer speed to the TC several times by moving a 1GB file and it only took a little over a minute. The 1 GB per minute speed also was consistent with the time it took to backup of my iMac harddrive to the TC over ethernet. Don't know how to explain this difference from those experiencing much slower transfer rates. Could it be that when you are connected by ethernet your airport connection is still active and the transfer of data is taking place over the wireless connection instead?? Moving data between the TC and a connected USB drive, however, is very slow for me.

DNS Server for VIP

Here is the example i am trying to use, while connecting to the database from the client machine.
We are building a Domain Name System (DNS) server. Do we need to include the VIP Address in the DNS list ?
RAC =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = rac1-vip.lynx.co.uk)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = rac2-vip.lynx.co.uk)(PORT = 1521))
(LOAD_BALANCE = yes)
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = RAC.WORLD)
Thanks

Prasad,
I did not get the context of the question but if you check this link :
http://download.oracle.com/docs/cd/B19306_01/install.102/b14203/prelinux.htm#sthref375
it makes the following points :
One virtual IP (VIP) address with an associated network name registered in DNS. If you do not have an available DNS, then record the network name and VIP address in the system hosts file, /etc/hosts. Select an address for your VIP that meets the following requirements:
1) The IP address and network name are currently unused
2) The VIP is on the same subnet as your public interface
Before installation, check that the default gateway can be accessed by a ping command. During installation, OUI uses the ping command to ensure that the VIP is reachable. To find the default gateway, use the route command, as described in your operating system's help utility. After installation, configure clients to use either the VIP address, or the network name associated with the VIP. If a node fails, then the node's virtual IP address fails over to another node.
Please clarify if this was'nt your original question ..

Moving from Exchange 2007 to 2013 (leaving the DNS Server for it's own dedicated server)

Hello! I am quite new to Exchange and Server management in general. I will do my best to explain my situation.
I am looking to move my Exchange server off of our DNS server. When we installed them on the same server, we did not have the funds to buy 2 separate servers. I am told that it is best to separate the two. I have followed the Microsoft instructions for installing
the prerequisites for Exchange 2013 on a 2012 R2 server, and i am at the point where it wants me to configure AD LDS. As I have active directory running on the current server, I was a little hesitant to just install it without understanding what i am doing.
After the AD LDS is configured, I believe i can move forward with installing Exchange 2013 (all 3 roles will be hosted on the new server), export the mailboxes from 2007 server and import them into the new Exchange 2013 server. After 2013 is up and stable,
I plan on removing 2007 from the old server (DNS server).
What are my next steps after importing the mailboxes? Am i missing important details that I need to change or migrate?
My biggest fear is that nothing works after the installation and moving the mailboxes over. For that case, it makes sense to keep 2007 installed as a fallback for when my installation fails and all i have lost is just my time :)
Current Server:
Windows Server 2008 Standard (64 bit)
1. Roles: Active Directory, DNS, IIS
2. Software: Exchange 2007
New Server:
Windows 2012 R2 Server
1. Roles: ???
1. Software to install: Exchange 2013
Thank you for any help you can provide!

These are good resources, but i am still caught up with the active directory issue. Am I able to keep the old Domain/DNS/Active directory on it's current server and move Exchange 2007 off onto a new server (with Exchange 2013)?
In the first example, he is moving everything (domain controller, exchange, users, etc) onto a different server and decommissioning it.I've been told that it would be better practice to keep the domain and exchange on 2 different servers. Is this true?
I go to run commands like:
.\setup /PrepareAD /OrganizationName: orgname /IAcceptExchangeServerLicenseTerms
on the new exchange server, as a prerequisite and it doesnt recognize the command - even after following the steps before. Is this because the new server is not a domain controller? does it have to be? What are the best practices for setting up a server(s)
with exchange + domain controller?
Thanks for responding.

2K8 - Best practice for setting the DNS server list on a DC/DNS server for an interface

We have been referencing the article
"DNS: DNS servers on <adapter name> should include their own IP addresses on their interface lists of DNS servers"
http://technet.microsoft.com/en-us/library/dd378900%28WS.10%29.aspx but there are some parts that are a bit confusing. In particular is this statement
"The inclusion of its own IP address in the list of DNS servers improves performance and increases availability of DNS servers. However, if the DNS server is also a domain
controller and it points only to itself for name resolution, it can become an island and fail to replicate with other domain controllers. For this reason, use caution when configuring the loopback address on an adapter if the server is also a domain controller.
The loopback address should be configured only as a secondary or tertiary DNS server on a domain controller.”
The paragraph switches from using the term "its own IP address" to "loopback" address. This is confusing becasuse technically they are not the same. Loppback addresses are 127.0.0.1 through 127.255.255.255. The resolution section then
goes on and adds the "loopback address" 127.0.0.1 to the list of DNS servers for each interface.
In the past we always setup DCs to use their own IP address as the primary DNS server, not 127.0.0.1. Based on my experience and reading the article I am under the impression we could use the following setup.
Primary DNS: Locally assigned IP of the DC (i.e. 192.168.1.5)
Secondary DNS: The assigned IP of another DC (i.e. 192.168.1.6)
Tertiary DNS: 127.0.0.1
I guess the secondary and tertiary addresses could be swapped based on the article. Is there a document that provides clearer guidance on how to setup the DNS server list properly on Windows 2008 R2 DC/DNS servers? I have seen some other discussions
that talk about the pros and cons of using another DC/DNS as the Primary. MS should have clear guidance on this somewhere.

Actually, my suggestion, which seems to be the mostly agreed method, is:
Primary DNS: Locally assigned IP of the DC (i.e. 192.168.1.5)
Secondary DNS: The assigned IP of another DC (i.e. 192.168.1.6)
Tertiary DNS: empty
The tertiary more than likely won't be hit, (besides it being superfluous and the list will reset back to the first one) due to the client side resolver algorithm time out process, as I mentioned earlier. Here's a full explanation on how
it works and why:
This article discusses:
WINS NetBIOS, Browser Service, Disabling NetBIOS, & Direct Hosted SMB (DirectSMB).
The DNS Client Side Resolver algorithm.
If one DC or DNS goes down, does a client logon to another DC?
DNS Forwarders Algorithm and multiple DNS addresses (if you've configured more than one forwarders)

I agree with this proposed solution as well:
Primary DNS: Locally assigned IP of the DC (i.e. 192.168.1.5)
Secondary DNS: The assigned IP of another DC (i.e. 192.168.1.6)
Tertiary DNS: empty
One thing to note, in this configuration the Best Practice Analyzer will throw the error:
The network adapter Local Area Connection 2 does not list the loopback IP address as a DNS server, or it is configured as the first entry.
Even if you add the loopback address as a Tertiary DNS address the error will still appear. The only way I've seen this error eliminated is to add the loopback address as the second entry in DNS, so:
Primary DNS: The assigned IP of another DC (i.e. 192.168.1.6)
Secondary DNS: 127.0.0.1
Tertiary DNS: empty
I'm not comfortable not having the local DC/DNS address listed so I'm going with the solution Ace offers.
