Adding a Server 2008 R2 Domain Controller at a remote site

Hello. I have been trying to set up a hot site at a remote location. The story is long and involved but a few weeks ago it seemed to be finally working. Our setup is two mirrored 2008 R2 servers at main site, mirrored with Double Take.
The hot site is the same except that so far I only had one server working. The two sites connected via site to site VPN.
About a week later our primary server basically crashed. At first it worked but very slowly. I was on vacation at the time and so I am not sure of the sequence of events, or exactly what errors were presented, but my associate first tried rebooting.
It took over 20 minutes to boot and then it said something to the effect that no domain controllers were available (not sure about this message). He then discovered that the server at the remote site had some fsmo roles assigned to it. He transferred
the roles to the primary at the main site and then demoted the remote server to a workstation (but still a domain member).
After that, rebooting the primary was much faster and everything at the primary site is working again. Now I want to set the remote site up again, but avoid the problem. The way I originally set up the remote server was to use an IFM file, generated
from our primary. This should have made the remote server a catalog server, with DNS (which it did), but as far as I know should not have transferred any fsmo roles.
The remote server(s) are wanted to be in the same domain as the primary. They will also be mirrored from the primary (with Double Take). If we had total failure at the main site, we wish to be able to immediately begin operations at the hot site
(after a fail over). I freely admit that I am swimming out of my depth here. I am not sure that I have selected the correct architecture or used the correct options in setting up the remote servers. I am looking for information about what
went wrong, and whether some other setup is more desirable.
Thanks for any help, Russ

Philippe, thank you for you answers. I do not understand everything you said but I will address each point as best I can:
1. "In the remote site do you simply do a dcpromo / add the ADDS's role to make the server a active Domain Controller ?" Yes, but I use the method described at
http://technet.microsoft.com/en-us/library/cc753720(v=ws.10).aspx, The GUI method. At step #8 I specified to use advanced mode so I could use the IFM file.
2. "In your AD' Site and Service MMC, do you configured the remote site ?" R do not know what you mean by this. How does one configure the site as 'remote'?
3. "Do you added that remote server as a Global catalogue ?". Yes, when I built the IFM file I specified to add the global catalog.
4. "Do you added the PC in site 1, the IP of those DNS server in them ? (last of course) So the computer in the main site will talk to the remote server in case of a crash." I am not sure I understand this item. After the remote server
was added, all of the members of both domain servers automatically appeared in the DNS of all servers in the domain. I do not recall if the new items were last, but I expect that they would be.
I have since reviewed the happenings with my associate and have a little more information. The order of the problems and the actions taken are:
1. Our primary (production) system was still working but extremely slow, and he observed that the slowness was caused by a lot of traffic with the remote site. Rebooting the production server took over 25 minutes and the server to came up saying
that domain information was not available. After another 30 minutes or so he discovered that the domain data was now available and the server worked, but still slow.
2. He did not check to verify that roles were held by the remote server, but he transferred all roles from the remote to the production server using ntdsutil. I would expect that if the role was not held by the remote, the transfer command would have
shown that fact.
3. He then tried to demote the remote server but had an error that it could not be demoted because "the active directory service is missing mandatory configuration information".
4. He forcefully demoted the remote server.
5. After rebooting the production server again performance was slightly better but still slow (and the rebood was still very slow).
6. After some research he removed the remote domain controller's meta data from the production server and then rebooted the production server again.
At that point reboot was fast (under 5 minutes) and the production system was working at normal speed again.
All of the above leads me to believe that somehow the FSMO roles got added to, or moved to the remote site when I used the IFM file to create the new domain controller. However nothing I have read says that this should happen. I hope someone
here can give me a better answer as to what caused the problem, as I do not wish to interrupt our production system like this again.
Thank you, Russ
PS: Sorry for the delay in getting back to this but some other priorities took me away from it for a week.

Hi Lawrence,
After configuring the GPO, did we run command gpupdate/force to update the policy immediately on domain controller? Besides, please run command gpresult/h c:\gpreport.html to check if the audit policy
setting was applied successfully.

Windows Server 2008 R2 Domain Controller NOT logging EventID 4740

EventID 4740 (account lockout) is not being logged to the event viewer. When searching through the security log there are none to be found. Having accounts locked out and no logging is driving me nuts. Hope someone has run into this before. This is what
i have checked thus far.
>Windows Server 2008 R2 Domain Controller
>Verified the following GPO settings are set and correct:
>Computer Configuration\Windows Settings\Security Settings\Local Policies\Audit Policy\ all are set for Success & Failure
>Computer Configuration\Windows Settings\Security Settings\Advanced Audit Configuration\Logon/Logoff) is set for Success and Failure
>Powershell command Get-Eventlog -log Security -InstanceId 4740 returns no results which makes sense since there are no entries in the security log file.
>No 4740 entries in the netlogon.log debug file
AD and the LockoutStatus tool show the account is locked out but i still have nothing in the logs.
Anyone have any ideas? From everything i can find online , it appears i have everything set properly.
Thanks, Chico

Hi Chico,
I suggest you try to enable this group policy below:

Upgrade Server 2008 Enterprise Domain Controller to Server 2012 Standard?

Hey there,
We are going to be attempting to upgrade several of our Windows Server 2008 Domain Controllers in our satellite offices from Windows Server 2008 Enterprise to Server 2012 Standard. I know the inplace upgrade will work (tried it on a member server)
but are there any caveats being that they are Domain Controllers? Contacted Microsoft and they said we shouldn't have any issues upgrading, and there is nothing special that has to be done in preparation. (I thought for sure we would have to DCPromo
down before and dcpromo up after the upgrade, but not so much, according to MS) But I figured I would check and see if anyone has done this successfully. I should mention that we already have 2, Windows Server 2012 Domain Controllers in our environment,
and one of them has the FSMO roles. Thanks in advance!

It should work with no problems. My favorite options remains always to demote the DC, re-install it completely and then promoting it again: This is just my own way to work as it makes me sure that I start with a clean base with the fresh install.

Best Practices for Setting up a Windows 2012 R2 STD Domain Controller in a Remote Site

So I'm looking for an article or writeup similar to the "Adding Domain Controllers in Remote Sites" TechNet article but for Windows Server 2012 STD R2. Here is my scenario:
1. I want to setup the domain controller at Site A where the primary domain controller is located. The primary domain controller is Windows Server 2008 R2.
2. Once the DC is setup I plan on leaving it on our network for a few days before shipping it to remote Site B for installation
Other key items:
1. The remote Site B will have a different IP range than Site A but will be connected to Site A via a single VPN tunnel. All the DCs that replicate with each other are on the same domain.
2. The 2012 DC that I setup for Site B (same domain in same forest) will be a DHCP, DNS, and WSUS server all replicating to the primary DC at Site A
Questions:
1. What items can I setup while it's at Site A without effecting or conflicting with the existing network and domain controller? Can I setup a scope once the DHCP role is added?
2. All of our DCs replicate through Sites and Services, do I have to manually add this to our primary DC for the new DC going to remote Site B? Or when does this happen automatically when I promote the DC?
All and all I'm just looking for a list of Best Practices for 2012 or a Step by Step Guide. Any help would be appreciated.

Hi,
Thanks for your posting.
When you install AD DS in the hub or staging site, disconnect the installed domain controller, and then ship the computer to the remote site, you are disconnecting a viable domain controller from the replication topology.

I suspected some issue with AV so uninstalled.
To resolve the Access Denied I followed these steps:
stop w32time
w32tm /unregister
reboot
regsvr32 /u w32time.dll
w32tm /register
sc query w32time -- you should see that the service is set to
shared mode -- this is presumably how it should be -- if you try to start right now, you'll get the expected 1290 SID-related error
reboot
w32time should now automatically start at boot up and be running -- that was my result -- it's running as shared, started on its own, and I can do the w32tm /query commands successfully
After rebooting the time service started.
I then repeated the steps:
net stop w32time
w32tm /config /syncfromflags:manual /manualpeerlist:"0.pool.ntp.org, 1.pool.ntp.org, 2.pool.ntp.org"
w32tm /config /reliable:yes
net start w32time
w32tm /query /configuration
And all worked. I'll wait a short while to see if this fixes the issue. I also have am SA case with MS so will confirm fix when resolved.

Add Windows Server 2012 R2 domain controller to Windows 2008 R2 domain

Hi,
Have today 2 x Windows Server 2008 R2 domain controllers, and domain and functional level 2008 R2.
We now want to replace these DC`s with Windows Server 2012 R2.
My plan is as follow
- Install and promote a Windows Server 2012 R2 as a 3 DC`s with a temporary hostname and IP as DC3
- Install and promote a second Windows Server 2012 R2 as a 4 DC`s with a temporary hostname and IP as DC4
- Decomiss DC1 and remove this host. Change the IP and hostname of the new DC3 to DC1
- Move FSMO roles from DC2 to DC1 and decomiss DC2
- Change the IP and hostname of the new DC4 to DC2
Will this be a ok progress ? I will offcours to have the DC`s replicate information between them before doing each task.
/Regards Andreas

Hi,
Only error i got running dcdiag was the following
Starting test: NCSecDesc
    Error NT AUTHORITY\ENTERPRISE DOMAIN CONTROLLERS doesn't have
       Replicating Directory Changes In Filtered Set
    access rights for the naming context:

    access rights for the naming context:
    DC=DomainDnsZones,DC=domain,DC=local
    ......................... DC1 failed test NCSecDesc
Is this a problem ?
I would guess not since im not implementing a RODC ? Ref:

Unable to edit Default Domain policy on Server 2012 R2 domain controller

Hello,
I recently built a Server 2012 R2 domain controller and added it to my domain. When trying to edit the default domain policy I get the following error:
I can make edits to other GPO objects. All the other domain controllers are Server 2008 and are able to edit that GPO. The issue is on the Server 2012 box only. I've checked the delegated permissions, I'm a domain admin, and have opened
GPMC as administrator. Does anyone know what I'm missing? Thank you for your time.
Tino

Hi Tino,
>>Could that be the problem?
I don't think so, for we can still use FRS to replicate Sysvol. However, it is recommended that we use DFSR to replicate Sysvol if our domain
function level is Windows Server 2008 or above.
Besides, we can follow the suggestions from the following thread to check out which replication mechanism we are using.
DFS-R on 2008 R2 by default?
http://social.technet.microsoft.com/Forums/windowsserver/en-US/8f2042d3-193d-4414-b9da-cbcedc6a4c32/dfsr-on-2008-r2-by-default?forum=winserverDS
If the Sysvol is replicated by FRS mechanism, as I suggested in the last reply, we can do a non-authoritative restore for the Sysvol on the new Windows
Server 2012. This will restore the Sysvol from a healthy DC.
To perform a nonauthoritative restore, stop the FRS service, configure the BurFlags registry key, and then restart the FRS service. To do so:
1. Click Start, and then click Run.
2. In the Open box, type cmd and then press ENTER.
3. In the Command box, type net stop ntfrs.
4. Click Start, and then click Run.
5. In the Open box, type regedit and then press ENTER.
6. Locate the following subkey in the registry:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\NtFrs\Parameters\Backup/Restore\Process at Startup
7. In the right pane, double-click BurFlags.
8. In the Edit DWORD Value dialog box, type D2 and then click OK.
9. Quit Registry Editor, and then switch to the Command box.
10. In the Command box, type net start ntfrs.
11. Quit the Command box.

How to reset Windows 2008 R2 Domain Controller "Administrator" password?

Hello Everyone,
I have lost Administrator password for the following system:
Windows 2008 R2
Domain Controller setup on same machine
Stand alone server - no workstations or other servers invovled
I still have the "Directory Service Restore Password" but I don't think that helps me for lost Administrator password. I beleive I need to boot from an .iso file to gain access. I already tried "Offline NT Password & Registery Editor" and it has set
Administrator password to (blank) but that is not allowing me access as it seems that I have to login to domain controller Administrator. So, how can I reset that password?
Thanks

It wasn't difficult to reset the domain password and I think Microsoft's policy of not providing an easy forward way is to create an
illusion of security which is not there. Linux systems that are much more secure that MSFT software allow easy password reset when physical access is there so why not include the same tools in System Repair tools or using F8?
Anyhow, this guide helped me reset the password in 5 minutes. Read the bottom of it to find the scripted / automatic version of the process:

Hi All,
I have not found any TechNet Article which states about the Windows Server 2012 R2 Active Directory domain controller operating system support with Exchange 2007 RTM, can some one please let me know that does Exchange 2007 RTM supports Windows Server 2012

There are several likely reasons for this. The most significant is that Exchange 2007 RTM is no longer supported (outside ot extended support, which is not going to include adding support for new operating systems):

You'll note from the following -

Windows 7 or Windows Server 2008 R2 domain join displays error "Changing the Primary Domain DNS name of this computer to "" failed...."

Hi,
Windows 7 or Windows Server 2008 R2 domain join displays error "Changing the Primary Domain DNS name of this computer to "" failed...."
DC:windows Server 2008 R2
Domain functional level:Windows Server 2003
When Winxp join domain, have no this error message.
I checked http://support.microsoft.com/kb/2018583?wa=wsignin1.0 does't work.
There have 3 suggestion in this article:
1.The "Disable NetBIOS over TCP/IP" checkbox has been disabled in the IPv4 properties of the computer being joined.
Doesnt's work.
2.Connectivity over UDP port 137 is blocked between client and the helper DC servicing the join operation in the target domain.
On my DC, I run netstat -an, reslut as below:
UDP 192.168.20.3:137 *:*
3.The TCP/IPv4 protocol has been disabled so that the client being joined or the DC in the destination domain targeted by the LDAP BIND is running TCP/IPv6 only.
We are not using IPV6.
This server recently updated from Windows Server 2003 to Windows Server 2008 R2. Before upgrade, when Win7 and Win2008 join this domain, also have the same error message.
Please help to check this issue.
Thank you very much.

Hi Guo Ying,
I have faced this critical error which makes over-writes the host names in the domain when you join.
For example: Already you had a host name called as PC.domain.com in the domain.com Domain.
When you try to add the another host name called as PC in the domain.com Domain, it doesn't give you the duplicate name error on the network it does over-write the existing host name called as PC.domain.com & it will add the new host name into the domain.
Host name which got over-written will get removed from the domain. I faced this issue in my project. My DPM host name got removed from the Domain & new host name got joined into the domain which halted my backups for one day.
Final Resolution is as follows:
You need to start the dns console on the DC & drop down the domain name.
Select the _msdcs when you click on _msdcs it will show the Name Server's list on the right hand side.
You need to add the Domain Naming Master under the _msdcs or add all the domain controllers which you had.
After you add the Name server's try joining the PC OR Laptop to the domain which is successfully joins it.

Group Chat feature in Office Communications Server 2007 R2 does not work in Windows Server 2008 R2 domains

   Hello to all, there are two confliting articles about this topic:
   1-
http://technet.microsoft.com/en-us/library/upgrade-domain-controllers-to-windows-server-2008-r2(v=ws.10).aspx#BKMK_Whatsnew : this one says that it does not work "The Group Chat feature in Office Communications Server 2007 R2 does not work in Windows
Server 2008 R2 domains". This article was updated in 2013.
   2-
http://technet.microsoft.com/en-us/library/ee692314(office.13).aspx: this other article says that it will function "Office Communications Server 2007 R2 Group Chat will function in a Windows Server 2008 R2 forest". This article was updated in
2010 and was refered by the first one.
   What is the correct support position for Group Chat feature in Office Communications Server 2007 R2 and Windows Server 2008 R2 domains?
   Regards, EEOC.

Hi,
I notice the following sentence in the link below “Office Communications Server 2007 R2, Group Chat will not function in a Windows Server 2008 R2 forest or when Group Chat member servers are joined to a Windows Server 2008 R2 domain.
We know of an issue with changes in Windows 2008 R2 that requires a Group Chat Client and Group Chat Admin Tools hotfix. The Group Chat Client and Group Chat Admin Tools hotfixes are currently scheduled for mid-April 2010.”
http://blogs.technet.com/b/nexthop/archive/2010/11/06/supportability-for-office-communications-server-2007-r2-and-windows-server-2008-r2.aspx
So in my opinion, if you update to the latest version of Windows Server 2008 R2, OCS Server 2007 R2 and Group Chat Client, Group Chat Admin Tools to the latest version, it should work.
However, the best method for you is make a lab to test the problem firstly.
Best Regards,

10.5.7 server as primary domain controller

Setting up a 10.5.7 server -
Server is setup as a open directory master, I want it also to be a primary domain controller (smb).
But when I try to change it from Standalone Server to primary domain controller, using my directory admin user id and password, it just reverts back to standalone server. tried it with smb running and not running.
Any ideas ?

Having the same issue with Leopard Server 10.5.8.
SMB was previously set up as a "Domain Member" and now I want to make it a "Primary Domain Controller".
After reboot, the Role always reverts back to "Domain Member".
Any ideas?

Biztalk 2013 R2 with Windows Server 2003 R2 Domain Controller

Hello, I have a client right who has a Windows Server 2003 R2 domain controller with active directory installed. Is there any reason why I can't install Biztalk 2013 on a Windows Server 2012 R2 box and add it to that farm to use active directory?
Thanks in advance,
-Adam

BizTalk Server is only going to use the User Groups created in Domain Controller so ideally i don't think there will be any compatibility issue. Also there isn't any microsoft article which talks about BizTalk compatibility with respect to domain controller.
You will have to create all the Windows Groups and User Accounts in AD, before BizTalk Server configuration.

Exchange Server 2013 and Domain Controller

Hello,
I am planning to install domain controller and exchange server 2013 in same server hardware. Is that not recommended? If not, why is it no recommended?
Thank you in advance,

thanks for such a quick response.
Just a small question about the link that you put. Does member server mean other server other than domain controller?
Regards,
Yes, Also the server on which you are installing Exchange should have exchange installed.
