Vista Slow After Windows 2003 SP2 Installation

Problem:  Installed Server 2003 SP2 on my exchange server and all went well.  I, however, had issues accessessing files and my mailbox.  I could access all the other servers fine but not this one.  To top it off, the other users in the office weren’t having any issues so I knew it was a problem with my box.  Tried everything from rebooting, updating vista, removing programs but nothing would work.  Finally, I realized that I’m the only one on the network with Vista and that was the issue.

Solution: Did some searches and found out that the Vista TCP/IP “Receive Window Auto-Tuning ” was the issue.  I executed both commands below, rebooted and all was well.

netsh interface tcp set global rss=disabled
netsh interface tcp set global autotuninglevel=disabled

Thanks to Diva Blog for saving me some time troubleshooting this.
