Remote Desktop to the Server a crawl after Windows 2003 SP2 Instal

Symptoms:
After installing Windows 2003 SP2 on Windows Server 2003 R2 Enterprise
64-Bit Edition, remote desktop to the server is at a crawl. Once connected
the login screen moves extremely slow. It begins painting the display very
slowly. One you login successfully it ends up locking up or disconnecting.
Once I uninstalled SP2, using Remote Desktop works perfect. We just got 3 new
64 Bit servers and had this issue with all 3 after installing SP2. On one of
the machines I installed a Windows Server 2003 R2 Enterprise 32-Bit Edition
and installed Windows 2003 SP2 and remoted desktop works great. I believe to
have narrowed the issue done to installing SP2 on the 64 bit edition of
Windows Server 2003 R2 Enterprise. I am pretty sure this is a bug after
several days of troubleshooting.

MVPs might want to take a good look at this one.

 

Disabling some of them client-side solves the problem:
Use the right click & runas option command on the command prompt on the
client and server side. Run the following commands:
netsh interface tcp set global rss=disabled
netsh interface tcp set global autotuninglevel=disabled
and reboot
or
Also on another Server that I applied SP2 had Remote Desktop go to a crawl.
The fix is to start the Windows Firewall service on the Windows 2K3 SP2
server. No reboots or logoff logon reaquired. No Firewall Configuration
required
