Yesterday I was trying to install a network printer on Windows Server 2008 system. After typing printer’s IP address, I received an “Access denied” error.

The problem was that I tried to install the printer while I was logged on with a user that had domain admin privileges, but not the default domain Administrator account.
When I logged in with domain admin user – Administrator – I was able to install the printer successfully.

Searching the internet, I saw that some people are saying that this error appears only when having UAC turned on.
