I have recently started working with a customer that has multiple POS systems. We migrated from a Windows SBS 2003 server to a 2011 SBS machine. They had implemented group policy some years back for the purpose of preventing employees from accessing the internet and only allowing them access to the POS application.
All POS computers are in a container called POS. All are XP machines.
So here is the problem. Because these are all 32-bit computers, the 32-bit print drivers wouldn't work on the server. This was fine; installed them locally. However, one of the workstations 'XP6' isn't acting like the others.
I deleted the old printers, reinstalled the new ones. Rebooted the computer and they all came up fine...or so it appeared. I uninstalled an outdated AVG, which went fine. Again, so it appeared. When I rebooted the machine all my changes made were reversed. The printers were still mapped to the old 32-bit server which is no longer on the network, and AVG acted like it never was uninstalled.
I used Your Uninstaller, reran the uninstall of AVG. Same results. There is no reinstallation of software as would happen; it's almost like a roaming profile or something is keeping not only all the settings but applications as well. I'm at a loss and hoping for some direction here.
Oh; the person that put this system together has moved on and documented nothing. I am shooting in the dark here.
Thanks everyone for the help!
