During my migration from SBS 2003 to 2 new servers 2008 R2 i encounter the problem that one of the new servers 2008 R2 (X64) hangs on "Please wait for the group policy client"
The problem is when the server is using itself as the primary DNS server (local ip sepcified) in the tcp/ip settings.So when i add as secondary DNS the SBS2003 for example.there is no problem and the server logs on quickly.
on the server 2008 tcp/ip V4 and 6 are both enabled,and configured to registrate itself in DNS.
I specified a static entry in the tcp/ipV6 settings with help of the SixXS tool.
I believe that DNS database was missing some records for the server but after the ipconfig /registerdns i see NS,A and AAA records now.
