Installing OCS 2007 R2 Group Chat Server on Server 2008 R2

To begin, follow the instructions here for the usual Server 2008 R2 workaround/fixes for Server 2008 R2 and OCS 2007 R2.

1. From an elevated PowerShell prompt: Import-Module ServerManager [Enter]
2. Install the prerequisites for Group Chat Server with: Add-WindowsFeature AS-NET-Framework,Desktop-Experience,FS-FileServer,NET-Framework-Core,MSMQ-Server,MSMQ-Directory,RSAT-ADDS,WAS-Process-Model,WAS-Config-APIs,Web-HTTP-Logging,Web-Mgmt-Compat,Web-Mgmt-Console,Web-Static-Content,Web-Windows-Auth [Enter]
3. Install KB 975858 so certificate based authentication works properly.
4. Install the OCS Group Chat Server as you normally would on any other operating system. Elan's guide is helpful for this (Part 1 / Part 2).
5. Install the OCS Core update from here and the UC API update from here. (If those links are outdated, go to KB 968802 for the latest links or use the ServerUpdateInstaller.exe)
6. Install the OCS 2007 R2 CU6 Group Server update from here. It is also a good idea to grab the Admin tools update from here and updated client from here.
7. At this point, if you try to start the OCS Group Chat Server services, they will stop without anything useful in the Event Logs. I'll save you time debugging this by pointing you to this older KB article here. You need to run %ProgramFiles%\Microsoft Office Communications Server 2007 R2\Group Chat Server\ServerConfigTool.exe so that the tool will update the Group Chat database schema to the QFE1 level.
8. After running the ServerConfigTool.exe, you'll be able to start the update OCS 2007 R2 Group Chat services.

Celebrate, at this point you'll have a working Group Chat install on Server 2008 R2.

Aaron,

Great post. Thanks for the information. Quick question, do you know if MS has fixed the issue with installing Group Chat into a Windows 2008 R2 Domain?

Not sure - does Group Chat break for sure with a domain level of 2008 R2?

I also heard there was an issue with Group Chat working in a 2008 R2 level domain. I have not seen any posts related to that being fixed, but any information you can provide would be great.

This is where I most recently read this:

http://technet.microsoft.com/en-us/library/ee692314(office.13).aspx

Office Communications Server 2007 R2, Group Chat will not function in a Windows 2008 R2 forest or when Group Chat member servers are joined to a Windows 2008 R2 domain. The changes in Windows 2008 R2 that affect the Group Chat client and Group Chat administrative tools are known issues and solutions are being investigated. For more information regarding upgrading a domain controller to Windows Server 2008 R2 operating system, please refer to the following Knowledge Based Article 982020 at http://support.microsoft.com/kb/982020/.

Thanks-
Nick

I'm waiting for a response from the product group about this one. I'm hoping to have some sort of answer soon.

Thanks Aaron!

And that didn't take long - GC is supported with 2008 R2 forest/domain level with CU6.

I guess the TechNet pages are lagging behind on getting updated to show the correct info.

Aaron-
Great news and thanks for that update!

Cheers-
Nick

Sweet, now you know that I am going to ask. Do they have this published anywhere?

#2.1.1.1.1.2 Matt Wade (Homepage) on 2010-08-31 14:25 (Reply)

They are waiting on the TechNet folks to get the references updated. That link above is most likely the one that is going to change/be updated, so keep an eye on that link.

This link comes up too quite a bit: http://technet.microsoft.com/en-us/library/ff621311.aspx

All in all, good news.
