Problem with Vista accessing a new Server 2003

I have been having a problem assessing a new 2003 server Enterprise from my
Vista Ultimate workstation. I have no problems assessing any other
computers in the office. Also, I have no problems assessing the new server
from any other computer.

My workstation is the only one running Vista.

I found a blog that recommended running the following "solution" on my
workstation, and it worked:

netsh interface tcp set global autotuninglevel=disabled

The blog had very little additional information with it.

What does this do?

Is there another better fix for this problem?

This seemed to happen after I added SP2 to the new server. Is there a
setting that should be corrected?

Thanks

I'm not sure exactly why you're seeing this problem. But in broad terms,
TCP/IP in Vista tries to autotune the "window size" of the send and recieve
buffers. This works great of the other end understands autotuning. If the
other end of the connection is not happy with window size autotuning, you
can see problems. There is a good description, here:

And a Microsoft KnowledgeBase article, here:

FWIW I have a Windows Server 2003 SP2 file server and I'm not seeing any
performance problems. So, it isn't universal. But it sounds like there are
enough people out there, who do see problems.

Trying a "netsh interface tcp set global autotuninglevel=restricted" might
be a good compromise.

Hope this helps a bit,
