I have a CMD script I run at each logoff. This is done by going into Group Policy and double clicking the Logoff entry under User Configuration | Windows Settings | Scripts (Logon/Logoff). The actual script I run is C:\WINDOWS\system32\GroupPolicy\User\Scripts\Logoff\logoff.cmd. This setup has worked fine for me for months. However, since installing GSS the other day, I see the following error in Event Viewer whenever I reboot: I assume that something in GSS, probably AppDefend, is blocking whatever process kicks off the CMD script. The problem is that, without a log being saved to disk, I have no idea what's really going on. Before I spend hours figuring out exactly what, can someone point me in the right direction?
