I've seen this problem when I prepare Dell PowerEdge 2950 servers using the Dell OpenManage Server Assistant 5.3 to install Windows Server 2003 R2 x64 with Service Pack 2.
Once the OS installation is complete, if you enable Remote Desktop and connect from a Windows Vista machine using RDP, the RDP session/screen refresh is kind of slow. This only happens with x64 edition of Windows Server 2003.
The problem seems to disappear when I install all the latest updates from Microsoft Update/Windows Update so I guess the issue is addressed in one of the fixes.

If you experience a very slow remote connection to Window 2003 servers from Vista here is what you need to do:
Run a command prompt (cmd.exe) as an Administrator
Type: netsh interface tcp set global autotuninglevel=disabled
If you want to to re-enable it:
Type: netsh interface tcp set global autotuninglevel=normal
Vista introduces a new feature called “Receive Window Auto-Tuning”.
There is an incompatibility between Microsoft Windows Vista and some network equipment and older Windows OS. Equipment possibly affected includes: Routers, VPN Endpoints, and Firewalls that use Stateful Packet Inspection (SPI).
Among most commercial firewalls that utilize Stateful Packet Inspection, the OSU Fire Marshall is one that is affected by this issue.
The problem has to do with the TCP window resizing feature in Vista and Stateful Packet Inspection.
