Hello,

I'm experiencing slow logins on our Windows 7 clients with Zenworks 11.0. After login the "welcome" screen can take up to about 10 minutes before the desktop appears. After that the Zenworks agent is not logged in.

Can anyone help me find out what the problem is ?

The log file contains the following:
