I've installed ZCM 10.3.0 on a Windows 2008 R2 server and configured a few bundles.

This worked fine last week, but today I log in on a client which has the adaptive agent installed and no bundles are appearing!

I can click refresh, but nothing happens. Also I can click "login" from the zenworks agent windows, but no login screen appears.

The adaptive agent properties screen show that the Primairy user is unavailable, could that be the problem?

How can I troubleshoot this?
