More fun today, some help would be greatly appreciated.
Added a Windows 7 machine into one of the workstation groups, which has various GPOs attached to it. When I log into the machine as administrator and run gpresult /z I can see the software installations streaming down the page, registering as assigned, but none of them have actually been installed.
I've had a look on the net and haven't found any documentation regarding problems with software deployment on Vista/7 so I've got no idea why it isn't installing. Any thoughts?
