you are unable to enable the new user for the OCS on ADUC (Active Directory Users and Computers) after introducing the Windows Server 2008

Posted by Mino on October 13, 2008

If you have an existing Windows Server 2003 forest running Office
Communications Server, and upgrade any of its domain controllers to Windows
Server 2008, Office Communications Server will not work correctly; some UI
elements will disappear, and you will be unable to add more Office
Communication Server servers or pools. To resolve this issue, you simply
reissue the command to prep the Active Directory forest for Office
Communications Server.

To do so using the user interface, use the Prep Forest option of the
deployment tool

(for more information, see “Running Prep Forest” in the Microsoft Office
Communications Server 2007 Active Directory Guide).

To prep the forest using the command line, use the following command:

LcsCmd.exe /forest /action:ForestPrep

After doing this, please check if the issue still exists. For more

Then please uninstall and reinstall  the OCS 2007 administrative tools on
the Windows 2008 domain controller. To do so, follow the steps below:

1. Insert the OCS 2007 installation CD media on the Windows Server 2008
domain controller .
2. Lunch the Installation and select to install the Administrative Tools.
3. After the Administrative Tools installation finished. Please check if you
could enable users for OCS 2007 from ADUC.
