Active Directory Enterprise Resource Pool Synchronization-ERROR

[Jonathan]

1. I configured Project Server 2007 to synchronize an Active Directory Group
with the Enterprise Resource Pool.
2. I scheduled this sync to occur daily at 1 am and to automatically
reactivate currently inactive users if found in the Active Directory sync.
3. This sync was successful without errors a few times, but now I get the
following error when I 'Saved and Synchronize now":
"Some user data was not updated because synchronization of the Enterprise
Resource Pool PARTIALLY FAILED on 2/11/2009 at 10:02 AM. To identify where
the errors occurred, see the Windows event log on the server."

The Application event log on the Project server shows a whole bunch of Event
7715 errors - an example shown below.

Any suggestions how to resolve this?
Thanks
Jonathan
