I have an existing SCCM 2012 installation that I'm trying to get upgraded to SP1. When I hit the pre-requisite check stage it complains about admin rights on the site server.
The server has admin rights to itself, I'm running the install from an account with domain admin rights, but I still get the error.
One thing I do see is the system it references is the public DNS name of the server not the internal DNS name.
Can someone please help point me in the right direction?
