Not sure if anyone else will see this, but we downloaded the windows xp security updates on a few test machines today and after applying the patches and rebooting everyone of them cannot authenticate to the ZCM server. It prompts for a password and when I type in my user id and password it says "Unable to log into network because the login credentials or the server certificate are incorrect."

The updates from Microsoft applied to these machines were kb980182, kb890830,kb977165,kb979306

Uninstalling zenworks agent and removing CASA does not fix this problem.
