I am having a variety of problems. For some reason, my dhcp server deauthorized. I tried to reauthorize it, and even tried to bring up another dhcp server, but they couldn't authorize with Active Directory. As a work around, we put dchp on our switch.
However, since the problem, when I try to remote to any of my 2003 or 2008 servers using RDP I get an error that says access is denied, contact my administrator. However, I can go in Vsphere and console in using the same network credentials with no problems. Has anyone ever run into this?
