I have a machine that did not pass WGA validation. Whoever we got them from did not use the proper product key for the install, but the COA shows a valid key, so I have been trying to update the key using Microsoft's product key update tool, but it fails every time with error 3-0x800004005.
Everything I have been able to finds tells me this error is related to antivirus and firewall interference, but I have both disabled while I run the tool.
At least I think I do. I've had some trouble turning off the firewall on the machine. The firewall is enabled through group policy, but even after creating a new OU in AD, creating a new GPO for that OU which disabled firewall and enabled loopback processing, dragging the machine in question into that OU and repeatedly restarting and running gpupdate/force, the firewall would still not turn off. I eventually disabled the service through the service manager. That should have effectively disabled the firewall, correct?
Anything that I am missing?
