We have a number of Windows 7 computers on our domain that get stuck on a "Please wait" screen for hours, and I have isolated it to a hung up GPO that has already been disabled, then deleted. The GPO previously installed, then removed, the Barracuda WSA client.
On one PC I tested this morning, the client was already gone as well as the GPO when I ran "gpresult" but in the System Error Log it still showed it as failed. I have to use Dameware to manually kill msiexec and then the Please Wait goes away, but this keeps happening. Any ideas?
