SYMPTOMS
You cannot join a Microsoft Office Live Meeting 2007 session as a domain user. Additionally, the following response is logged in the ConfAPI-uccp- .log file on the Windows-based Microsoft Office Live Meeting 2007 client:

Significant time skew detected during authentication.

This problem occurs if the following conditions are true:
 * The time on the Windows-based Live Meeting 2007 client differs by more than five minutes from the time on the domain.
 * The domain hosts Microsoft Office Communications Server 2007.
 * Communications Server 2007 uses Kerberos authentication.



CAUSE
This problem occurs because the time on the Windows-based Live Meeting 2007 client is not synchronized with the time on the domain.



RESOLUTION
To resolve this problem, make sure that the time on the Windows-based Live Meeting 2007 client differs by fewer than five minutes from the time on the domain. Typically, Kerberos authentication requires this condition.



STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the &quot;Applies to&quot; section.
