I have installed the RSAT for windows 7. When I try to open the Active Directory administrative center I cannot see my domain. When the program opens I can see the netbios name of my domain(local)--with a down arrow on it-- and when I try to change domain controllers I get error Cannot find available server for domain I can browse domain, can rdp to DC, DNS seems to be working on this box. this is Win & x64 RC. on a 2003 AD domain.
