Wasn't sure which forum to put this in, so sorry if I got it wrong.

Basically, we are running a 11.0 ZCM installation with Windows 7 and since two days ago the clients are randomly disconnecting from the ZCM server and the associated bundles and policies are (obviously) vanishing. If you reboot or right-click and login on the ZCM icon everything works fine. So does anyone have any idea why users are being logged out from the ZCM server ?

I've checked the user source and there are no errors on the workstations affected.

Hope someone can help,
