New hardware - revisiting dns/dhcp on small network

I'm trying to replace a failed SMC wireless router with a new Airport Extreme Base Station on our small network.
The network consists of OSX Server 10.4.x running on a G4, 6 wired client machines, and the occassional wireless client. Things were working fine with the old router, but web activity was sluggish, which I blamed on the router (but now suspect was due to my dns config). The router's wireless function broke, thus the effort to replace with Airport.
When things were working, I had the router dishing out ip addresses via dhcp, OSX Server was running DNS for its internal needs and to resolve for a few of our services that are hosted elsewhere.
The server machine was manually configured to look to the wireless router for routing , and look to itself for DNS. DNS could properly lookup and reverse lookup the server name from all machines.
Clients were configured to pick up ip addresses via dhcp, and dns from the server.
This worked, albeit web surfing was sluggish.
I had assumed dns requests were going through the OSX Server machine, which would in turn send them via the router address to my isp's dns (assuming its not one of the few records in my internal dns).
What I am suspecting now is that the client machines, when my server dns could not resolve a domain name, would turn directly to the isp's dns. I guess the dhcp would have supplied this info??? In other words, the OSX Server dns was not looking outside itself to resolve a name for which it didn't have a record.
Anyway - I feel like my problem lies somewhere in the server's dns. Question: How that the OSX Server dns resolve a request for which it does not have a record? Does it need an entry for an external dns it can forward the request to? Or does the ip address in the Network config's "Router" field cover that?
Many thanks.

As you are using "advanced services" in the server you should use only the server (internal private IP) DNS on your server LAN. Don't use any public DNS as they don't know your LAN private IP machines names or domainname.
The DHCP server in OS X should be setup to send out only the server IP for DNS to LAN clients and using the server DHCP it's possible to send LDAP info to clients too (you don't have to manually set directory services on each client to find your server).
In 10.5 Apple has provided the possibility of settig up DNS forwarders in the DNS GUI, in previous versions you have to enter them in /etc/named.conf "by hand" using the terminal (pico/nano).
Forwarders (usually your ISP DNS IPs) speed up dns lookups.
As it sounds like you are reusing your public domainname internally you seem to already have setup you public IP services too. This is neccessary for LAN clients to be able to find them as any domains configured in your local DNS will make the DNS server think it's the SOA (?) for those domains and it will not try to forward any requests/lookups for those to any external public DNS (DNS root servers or ISP DNS/forwarders).
If you have another static IP machine/server on your LAN you can make it a slave DNS so LAN clients can get at Internet if your server is temporarily down.

Single server as Soft AP, DC, DNS, DHCP for a small office

The server is running 2012 R2 Foundation with a wired network for internet (Comcast). It has a WiFi adapter so it can host a wireless network (as a Soft AP). The WiFi host has a static IP 1.1.1.1.
On the server I have setup AD, DNS, and DHCP services (all bind to that static IP).
All clients need to connect server and internet via WiFi, and join the domain for work.
But it looks like the DHCP/DNS services don't like the virtual adapter - although all clients can connect, they cannot get their IP.
Without AD/DNS/DHCP I can share internet connection with ICS perfectly, so I think the hosted WiFi network is setup correctly.
I tried to remove the DHCP service, and use ICS to assign IP - it works, but clients cannot see the DNS server and thus cannot join AD.
What am I missing? Thanks for your help!

It is never a good idea to run a DC with two NICS. It causes all sorts of problems. (The only exception was SBS server which was designed as a one-box solution). Also, a domain will not run behind ICS. If you are running a domain, the domain clients
must use the local DNS (on the DC) for DNS, not the DNS relay system of ICS. RRAS/NAT will work because you can configure it so that it does not run its own DHCP function. ICS is not configurable.
Even if you overcome that problem, you still have the multihomed DC problem. It really isn't worth the effort to save a few bucks.

DPM 2012 R2 UR4 and BMR backup from physical 2008 R2 (DC, DNS, DHCP,WSUS, WDS)

Hi,
I'm completely lost.
We updated from DPM2010 (2008 R2) to DPM 2012 R2 RU4 (2012 R2).
Clean install. Same hardware. Everything went quite smoothly.
Our new (and also old did the same thing) DMP protects some Hyper-V guest on our 2008 R2 Hyper-V cluster, one Exchange (2010) DB's and SQL 2008 R2 DB's and one physical server - 2008 R2 (DC, DNS, DHCP,WSUS, WDS ~160GB of data).
Currently we are using some Buffalo Terastation's III (TS-RIXL) iSCSI SAN storage to hold our DPM protected data.
Configured as RAID 5.
Our new DPM server is connected to those iSCSI devices using built in MS iSCSI initiator via secondary NIC on this server using dedicated iSCSI subnet.
Everything seems to be fine unitil System State and BMR (I'v checked both) runs.
Basically my iSCSI NIC shows Write about ~170Mbit/s and Read about 520Mbit/s when backing up virtual machines, Exchange or SQL.
When it comes to System State and BMR backup the trouhgput is MUCH slower (about 65Mbit/s) and I can not figure out why. I understand that the BMR backup initiates direct writing to the DPM created and shared replica volume on my iSCSI NAS (my wording
might be not correct but basically I understand how this works). But I don't understand why the speed is so much slower. I'v tried everything, googeled around, changed NIC drivers, firmware etc. No luck.
If I just copy some big ISO file from/to server to DPM or vice versa the speed is arount 100MB/s (as reported by windows itself). So it seems to able to utilize full network speed. But why this backup is so slow? I'm excpecting to see speed about ~170Mbit/s
because it corresponds my iSCSI Write speed as seen when backing up hyper-v guests and DB's..
What I'm doing wrong?
Any help is appreciated :)
rgds Sven

Hi Sven,
Sometimes BMR is slower than backing up virtual machines (VHDs). If there is a free local disk, please test to do a backup locally to see the speed. From your description a common backup works much faster so let's see if it is the backup speed which causes
the issue or not.

Backing up and restoring a member DC to new hardware.

Hello,
Sounds simple to me but I want to be sure on what I'm doing.
We have many sites with a domain controller at each location. The DC with all the FSMO roles is here at Corp. I need to move one of our member DC controller at a different site to new hardware. It is a Global Catalog, DNS, DHCP and file server.
Can I do this by using windows backup to back up System State, Bare Metal Recovery, System Reserve and Local Disk C: (Full Server) and restore it to the new Hardware as long as my HDD are same or bigger? Please remember this is a member DC.
I really hope to avoid the demotion of the current member DC and installing a fresh OS on the new hardware and promoting that to a DC.
Thanks

Hi,
If there are other healthy domain controllers online for the domain, we recommend that you do not perform a restore at all. Instead, perform a new installation of Windows on the destination computer and run the Active Directory Installation Wizard (Dcpromo.exe)
to make the installation a replica in an existing domain.
You can recover a member DC to new hardwarethe. The hard drives you are recovering data to must be as large as—or larger than—the drives that are included in the backup set.
For more detailed information, please refer to the articles below:

Best Practice to migrate existing Message/Central Instance to new hardware?

I've done some searching for this, but it all seems to be fairly old (I found one decent thread from 2008, but it just seemed outdated). I would like to get some updated info & suggestions on a process to follow for this task.
Here is some info about the current config:
I have an existing SAP ERP 6.0 EHP5 system. SID "XYZ"
Everything is currently running on Windows x64.
ABAP only config.
It is currently setup as a distributed system.
DB server is SQL, which is running on its own hardware as a dedicated DB server. I don't need to touch this.
Uses logon groups to distribute the load between 3 App servers.
One of the App Servers is setup as the Message/CI server. This is what I am wanting to move to VM hardware.
The other two App Servers are setup just as Dialog Instances. VM already. I don't need to touch these.
What I am wanting to do:
I am wanting to migrate the existing Message/CI server to VM hardware to get the current Message/CI system off of very old hardware.
I need to keep the system with the same name & IP.
I do not need/want to mess with the DB server at all.
Need to minimize downtime as much as possible.
I do NOT want to go to an HA environment. That is a different project for the future.
Suggestions? I would like to hear what some of you have done.
Minimize downtime? I have a short maintenance window of a few hours coming up in the next few months, and would like to do this changeover during that downtime.
How do I handle setting this up on the new hardware using the same name & IP, especially with the existing system still running.
What I think I need to do: (Some of these may be out of order, which is why I'm asking for suggestions)
Setup new Windows VM server, named differently than current Message/CI server (Done already).
Run SAPINST to run Global Host Preparation on the new Windows VM server.
Run SAPINST to setup ASCS Instance on the new Windows VM server.
Skip the Database Instance installation, since I already have one running.
Run SAPINST to setup Central Instance on the new Windows VM server.
Copy all of the appropriate profile parameters that were on the old server.
Start SAP and make sure everything is running and working correctly.
Copy all job, spool files, etc. from the old server.
What needs to be done in between those steps for the server rename & IP changes?
Which of these steps can I do in advance of my maintenance downtime window, without it affecting the currently running system?
I have a test environment that I am going to test this with. I'm just trying to get a jump start on my instructions, so that I can hopefully do this quickly and easily. I'm very comfortable doing the installs. Just needing some guidance on how to handle this case.
I'm open to suggestions, and any links you can send my way that show some more recent success at doing this. Everything I keep finding talks about doing the migration for the DB. I am not migrating my DB. It is staying where it is. I'm just wanting to migrate my Message/Central Instance to a VM, without affecting the users, and hopefully them never noticing the changes.
Thanks!

If you're using VMWare, there is a tool provided to virtualize existing systems. Basically it makes a copy of the old system (while it is down) and recreates it as a VM with the same name, IP, etc. I haven't double-checked to see if this process is 'officially' supported by SAP, and I don't know the technical details about how it's done or how long it will take (VMWare is managed by the Network Operations group in my team, so as the SAP sysadmin I'm basically a customer of theirs). However, we have virtualized a few smaller systems that needed to get off failing hardware in a hurry and it worked very well, so I would expect it would for an SAP dialog instance as well. As you're not copying a database, just the app server, it probably would fit within your maintenance window.
If this route works for you, then there is no need to actually install the SAP system on the VM instance... you just copy the old server as-is, then make any adjustments required due to no longer needing old drivers, etc, plus potentially having different memory parameters.

SQL cluster 2008 R2 migration to new Hardware in VM

Hi,
We have a task to migrate existing Physical SQL Cluster DB to new Hardware but in VM. (cannot argue with the client)
hence our plan is to install new Cluster in VM with same Windows and SQL version i.e Win 2K8 R2 ENT w/SP and SQL 2K8
R2 STD w/SP and use SQL mirroring option for the DB to migrate on the new Server (keeping the downtime to as low as possible and advantage of bringing the old server online in case of any issues..)
Below points are for a single instance, couple of DB to migrate:
Keep the physical production server running
In-Parallel build New SQL Cluster in VM (keep same version windows/sql)
Keep Same drive letter for Quorum, MSDTC, DATA, LOG & Backup
Keep the same Instance Name, SQL Network Name can be different (will be changed to old network name once the PROD is shutdown)
Check all logins windows and SQL to be same on both the clusters
Copy all the jobs, SSIS packages etc.. .create the location folder as per current server on the VM SQL Cluster
Perform full backup of old cluster company-db databases or use the existing latest backup (full, differential, transaction)
Restore databases in the new cluster with no recovery so additional log file or differential backup can be restored
Create SQL Mirroring for the Database and select the principal server (old cluster) and the mirror server (new VM cluster)
Choose mirroring without witness ( no auto failover as we don’t need the old server later)
Start the mirroring – (hopefully everything synchronized and working)
During the downtime –
Stop the application/ client connection – if possible
Failover the DB through Mirroring option
Once the mirrored server becomes Principal and data is accessible – stop the mirroring
Now the new VM SQL Cluster DB is online
Shutdown the old cluster company-db (Node1 & Node2)
Come back to VM SQL Cluster and change the Network name to the old server network name (so that client connections are not affected)
Check if the DNS entries are updated with correct name and IP address
Delete DNS entries for old company-db on DNS Servers if not deleted, delete the old server SQL network name in computer object
Stop SQL Resources on the new VM SQL Cluster (take it offline all the resources)
Bring online the SQL Resource and make sure the SQL resources are online and new network name is reachable
Wait till you see machine name company-db in active directly (AD) and DNS server will have entry for company-db
Verify connectivity for company-db from outside.
If things are not going as per the plan then shut down the new VM cluster
Revert back the DNS settings
Power up the Old SQL Server
The DB will show “restoring mode” – use command to make it online “RESTORE DATABASE (dbname) WITH RECOVERY”
Check the DB
Start using the OLD server again
Troubleshoot the failed scenario ;)
Need to know if the above steps are okay, and any consideration once the new VM SQL Cluster is online.
Kindly let me know if there anything else to transfer apart from the logins, jobs, folder location etc.. !!
Many Thanks

Hello,
Well if you don’t change the instance name (name = ABC) then its OK.
Try the following resources about transferring SQL Server logins:

WRT1900AC being used in small network

I've been using the WRT 1900 AC in a wireless configuration to support one laptops wireless internet access. Now I'd like to add it to a small network consiting of a laptop that is hard wired to network along with 10 other workstations all wired through a Cisco switch to a file server. Ther file server provides DNS, DHCP and Active Directory services along with access to system files. I've attached the WRT 1900 AC to the network via the Cisco switch using port 1 for the Ethernet connections. My problem is on the laptop I connect wirelessly to the WRT1900AC and can access the internet however I can't access the file server and when I can access the file server I can't access the internet. In my network settings I see two networks. One for the WRT1900AC that shows internet access and one for the file server that shows no internet access. I'm pretty sure there's a problem with where the laptop is getting it's IP address assigned from depending on what it can access. I've tried connecting the router directly to the file server and turning on ICS for that port on the server. The server can then connect to the internet but the wireless laptop can't. I haven't really messed with the other workstations but assume I'll have to do the same thing with them after I determine what needs to be done with the laptop.

Active Directory is heavily meshed with it's DNS Server and it's DNS registration.
The Linksys Smart Wifi firmware is designed to DNS proxy www.linksyssmartwifi.com to Linksys Cloud servers for Smart Wifi services like remote access but it also does this for local access to the router's UI.
If you specify your Active Directory DNS server in the DHCP settings to pass to the client devices AFAIK when you look on the client devices their DNS servers will always be 192.168.1.1 instead of your Active Directory DNS Server.
This breaks DNS registration and causes issues with Active Directory services and DNS resolution.
Please remember to Kudo those that help you.

New Domain controller, DNS client settings before FSMO transfer

I recently promoted a new domain controller. It is the fourth domain controller and third in the site. I plan to decommission the other two domain controllers in the site leaving just the new one. Right now the new domain controller points
its tcp\ip client to the other other domain controller\DNS servers as primary and itself at the bottom. The other domain controllers point to themselves as primary and the newest domain controller on the bottom of the list. Clients on the network
use the original domain controllers as DNS from DHCP first and then the new domain controller DNS. Is it okay to transfer all the FSMO roles to the new domain controller or should I make all the DNS clients point to it first?

Hi,
It is possible to first change your FSMO roles and after this is done then point your DNS clients to the new DC. This should not be a problem.
some interesting information about assigning your FSMO Roles: http://www.windowsdevcenter.com/pub/a/windows/2004/06/15/fsmo.html
Hope this helps you out.

How to migrate os x server to new hardware

I am looking for the quickest easiest way to migrate OS X server to new hardware that I purchased. I currently have both DHCP and DNS services actively running. I have VPN services running when needed.

Reid,
Thanks for your response. I actually migrated everything that I needed over about an hour after I posted. For DNS I simply copied all of the zone files in /Library/Server/named and restarted the DNS service. DHCP took a little more investigation as I had to find where the configuration file was being stored. I eventually found the configuration in /etc/bootpd.plist file that contains all of the DHCP info and copied it over to the new system. Once I restarted all services everything was working fine.
I took this approach rather than a direct cloning as I wanted a clean install of everything on the target system. Also, as I mentioned before, I didn't have many services running that I needed to have running on the new configuration. The VPN services that I was running had only one test user so recreating it from scratch was a non-issue.

André

Migrate SBS 2008 to new hardware

We have an SBS 2008 installation and are testing a disaster recovery solution by re-installing in Migration Mode.
Step 5 in the migration document from Microsoft discusses;
Demote and remove the Source Server from the network
We'd like to fully test this and get the backup box up and running before signing it off as a working solution.
Our concern is that, even if we isolate the test machine on a difference subnet from our production LAN, there is some kind of licensing consequence for our running box - via some kind of de-activation signal sent over the net, perhaps - should we continue
through the final steps.
Can anyone confirm or deny whether any kind of de-activation occurs? Perhaps paranoia, but thought best to check since we really can't have our live systems shut down.

Hi,
Before going further, would you please provide more detailed information about your concern? It’s difficult to understand your needs for me with the information you mentioned. For details about
how to migrate SBS 2008 to new hardware, please refer to the following articles.

DNS/DHCP Managment Console- IP Addresses not releasing

Hello,
I have added a new subnet on our network so we can add more wireless devices (iPads, Cellphones, etc. are all now needing IP addresses)
Everything is working fine except that the addresses are not releasing after 3 days. If someone with a Laptop comes into our building with a cell phone or laptop they are picking up an IP address automatically. Then once they leave (and the 3 day lease time expires) DNS/DHCP is not making that address available for another device.
Now we are quickly running out of local IP addresses on this new subnet. How can I get DNS/DHCP management console to hand out previously used expired IP addresses to new devices?
Thanks in advance!

Originally Posted by Marcel_Cox

Hello,
No we haven't run out yet so that my very well be the case.
We do have two subnets in the same building .30 subnet and .32 subnet
They both work, and any client can pickup an IP on either subnet.
The .30 subnet was the old one and the .32 subnet has just been created. Now all new clients pickup an address on the .32 subnet.
Is there any way to figure out why all the clients want to pull a .32 address now?
Thanks

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.

NEED HELP TO SET UP SMALL NETWORK - WIRELESS SIGNAL FROM NOVATEL U760 USB

Hello -
I need help setting up a small network in my new home in Florida, which has no wired broadband capability - not cable, not dsl. My options are satellite (which I'd like to avoid) or wireless broadband via Millenicom (or now Virgin Mobile) using their Novatel U760 USB stick.
Here are the network components - someone please tell me how to set this up:
PC #1 (has wireless card, but I've connected it by ethernet to the router)
PC #2 (no wireless card; connected via ethernet to router)
MACBOOK, 1 1/2 years old (2.1 GHz Intel Core 2 Duo, 4 gigs RAM), running OS 10.58, connected wirelessly to router.
AIRPORT EXTREME BASE STATION, Model A1143.
I'm not thrilled about using a wireless 3G signal as my primary one, (sprint network, claims 600 - 1400 kbps speed), but it costs 1/2 to 1/3 of what a slightly faster satellite signal would.
I have not ordered this service yet. Before I do, I'd like a clear understanding that I can, in fact, set up my simple network, which I'd probably do the same as it's now configured with cable broadband - both PC's plug via
ethernet into the Airport Extreme router, the MacBook connects wirelessly - AND,
my question is this:
Can I plug the wireless card - a Novatel U760 USB-stick device - straight into that USB slot in the Airport Extreme base station and will it automatically recognize that device?
Or, do I have to plug it into the MacBook and somehow share that wireless signal between the 2 PC's (only 1 of which has a wireless card, so I'd have to get a card for PC #2)?
And help anyone can provide will be much appreciated!
Thanks,
Em

from the Airport FAQ #14:
"Question: Can I connect my Soundsticks or other USB speakers to AirPort Express?
Answer: No. The USB port is for connecting a printer, not for other devices."
Im assuming other devices include USB modems.
So, I would say your cheaper route would be to get a second wireless card and just share your internet connection from one of your PC.

Communication between the DNS/DHCP Manager and OES Server

No communication between the DNS/DHCP Manager Console and OES server (status,start,stop)
The screenshot shows the tab "DHCP (OES Linux)" in the DNS / DHCP Manager console
in the bottom of the image it shows the state of the DHCP servers.
allDHCP.JPG
The dhcp service is started on all these servers
You can see that the status is known only for four servers.
The button "start/stop DHCP service" works fine on this servers and
the dhcp service can be canceled and also restarted
But the status of the "dhcp service" is not recognized for all the other DHCP servers
and so we can not start or stop dhcp service on these servers.
All servers were installed at different times (last three years) with OES11 and
are upgraded to OES11SP2 with all patches.
The server keto (DHCP_keto) is a new installation OES11SP2 few days ago.
All OES servers were set up identically from me. LDAP, LUM, DMS, DHCP works fine.
Which service on the OES server is responsible for
communication (status indicator) between the DNS/DHCP Manager and the OES serve?
How the status query is performed by the DNS/DHCP Manager?
How can I test the communication to the server on the client (console)?
Which configurationfiles I should be compare on the server?
Thanks in advance

DNS/DHCP app no longer sees DNS/DHCP server.

When I moved the majority of my Netware 6 servers to OES-NW last year, I started using iManager to handle admin duties for DNS and DHCP.
With a planned move to OES-L coming up, I tried accessing both services using the DNS/DHCP java console.
While I am able to log into that console, I am unable to see my DNS/DHCP server or any of the expected components for either service (DHCP pools, zone records, etc...).
I have tried both the console that is installable from the server and the newer LDAP-based version.
I have tried both 32 and 64-bit versions on XP and Windows 7, respectively.
Since I want to move those services to OES/Linux and the java console is the only mechanism that can administrate the services on that platform, I am perplexed.
My needs are simple, and I could easily move those duties to a SUSE server or even a Windows server, but that is not my preference.
Any ideas on where to begin troubleshooting are welcome.

You have more than one DNS-DHCP locator object in your tree, and the
console is picking up a/the empty one. Find the proper object (look at
the other tab in consoleone or imanager to see if it's connected with
servers zones and the like), and delete the superflouos ones.
This is an *extremely* common problem when OES gets introduced into a
tree, as it by default creates new locator objects in the server
container, if it's not configured otherwise.
