Three suggestions:<br />
<br />
- Can you restore the PCs before the update?<br />
<br />
- Or totally uninstall/reinstall client.<br />
<br />
- Or, do not install and wait for newest Communicator. &nbsp;I'm beta testing it now and should be out shortly. &nbsp;It will have a new name, but offer increased functionality and stability.

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:<br />
<br />
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.<br />
<br />
Is there something i would need to do on the OCS serve side of things to enable this new update? <br />
<br />
Should i try and decline the updates (only on 10% of computers right now). ?<br />
<br />
Thanks
