Setup new 10.1 ZCM from scratch on Windows 2003 server. LDAP communication with AD is working fine. ZCM Agent fails to login as any user from workstations, also agent fails to login from the Server!

Get the following Windows security message:

"Unable to log into the ZENworks realm because the system has disconnected from the network and the specified credentials do not match with the credentials cached on the system....etc."

I am getting this same message on the server itself, so it is NOT disconnected from the network.

Any help would be appreciated.
