Strangely enough, I see this error occasionally when I connect to our corporate Citrix server farm. Googling for the answer, I found Microsoft’s answer, which was less than helpful.
As my (Citrix) server administrators are only two desks away, I asked
“What gives???”
Windows does that, the fix is to delete the
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSLicensing
registry entry.
You can either do that manually, or use the registry file I created here.
