I've had a copy of WHS running quite happily for a few months now but a few days ago the server seemed to have gotten a bit sluggish so I connected in with remote desktop and did a reboot. All my clients then reconnected and my media players all work etc but when I try and use RDC I now get met with "a problem is preventing windows from accurately checking the license for this computer" and I get into the all too common loop of 'already activated', 'not activated' and I can't actually log into the server at all. I've tried numerous fixes such as replacing wpa.dbl and re-registering dlls etc but to no avail. Is there any way I can get out of this loop without having to do a re-install? Also, would it be possible to turn my current install into an OEM version or can this only be done at install time? I don't know why it should have chosen to lock me out at this point but it seems it's fairly commonplace for it to happen for both legit and illegit installs so is there any benefit to an OEM install with bios mod over the OOBETimer hack (the method I'm currently using)?
