“Failure [0xC3EC7814] Pool is not ready” while adding OCS Server to Pool

I was trying to get Office Communications Server 2007 (OCS) to work on our environment for the past few days and ran into some challenging issues.

OCS 2007 is being installed on Windows Server 2003 x64 R2 with SP2, and the SQL 2005 back end is on a separate machine. Co-existing the two on the same box is not supported.

Our environment used to have an LCS 2005 Pool, which had been decommissioned while setting out on the OCS adventure. The schema preparation, creating an enterprise pool, and configuring the pool – all went through successfully. The show-stopper was the ‘adding server to pool’ part.

During the ‘Add Server to Pool‘ wizard operation, the installation of the program files and some additional configuration succeeded. However, when it was time to activate the server, all hell broke loose and the operation failed.

When I opened the logs, The ‘add server to pool’ log file showed:

Failure
[0xC3EC796C] One or more errors occurred during execution of the wizard; the wizard was unable to complete successfully. Please check the log file for more information.

Drilling further down into the log, I found that the problem was while activating the server. I clicked on the link to open the Activation logs, and found the following generic error:

Failure
[0xC3EC7814] Pool is not ready.

After ironing out every logical possibility, days of searching the net, and after asking in the MVP Private newsgroups with no luck, I decided to contact Product Support.

A few hours later, the problem turned out to be remnants of the past LCS pools that were still lurking in the Active Directory. We opened up ADSIEDIT, navigated to the Domain partition –> System container –> Policies container. Over here, we found the GUID of the LCS 2005 pools and deleted them manually. Since we didn’t have any more LCS 2005 servers, we didn’t need them anyway.

Due to this, OCS 2007 Pools were not actually being created in AD, even though the wizard ran successfully. After a successful pool creation, OCS 2007 Pools should be seen in Domain partition –> System container –>  Microsoft –> Rtc Service –> Pools. However, the Pools container was apparently empty even after I created OCS 2007 pools.

Once we got rid of the LCS 2005 pool GUIDs mentioned earlier:

1. We removed the pool we created using the command lcscmd.exe /forest /action:RemovePool /poolname:<poolname> /force

2. Deleted the SQL 2005 database and log files for this pool

3. Re-created the pool from scratch starting with the ‘Create Enterprise Pool‘ wizard.

Server activation was successful and we are back in business!
