Windows 2003 Server with SP2 and Vista problems

If you are running with Windows 2003 x64 and have recently installed  SP2, you might be in for a mystery problem.  For Windows XP clients, everything is normal.  For Windows Vista clients, performance connecting to the servers is horrible.  If you run into that, check out this news group post:

I'll be checking this tomorrow at the office.  Our performance has been horrible since installing the service pack.

Update: I have been working on the two changes listed as solutions and they both seem to have solved the problem.

  1. With the Windows Vista client, I logged in as admin, set the following values, and rebooted the system.
    netsh interface tcp set global rss=disabled
    netsh interface tcp set global autotuninglevel=disabled  
  2. With the Windows 2003 R2 SP2 server, I turned on the firewall and then turned it off.
Performance now seems to be improved.  If things change, I'll let you know.
