I have a client where most of their XP machines just came up with the "Counterfiet" notice, and the computers said that a non-valid volume key was used to install. This client has the OEM XP versions sitting shrinkwrapped on the shelf. Original vendor is out of business. So I have re-installed and most went well. Except for one machine.
What I usually do in a repair install from the CD, boot into safe mode, install XP SP3 and IE 8. Then re-boot into regular mode and the machine comes up, states it needs to activate and then activates.
This machine however just boots to a blank blue screen, not the BSOD, just a blank blue desktop.
Another thing that seems weird is I get an "Access Denied" error when running msconfig.
