I deployed Windows Updates to our domain last night and our communicator clients will not connect. The Update i applied was KB 2028888. The error that i am seeing is:

Cannot sign in to Communicator. You may have entered your sign-in address, user name, or password incorrectly, or the authentication service may be incompatible with this version of hte program. If your sign-in information is correct and hte problem persists, please contact your system administrator.

Is there something i would need to do on the OCS serve side of things to enable this new update?

Should i try and decline the updates (only on 10% of computers right now). ?

Thanks
