Server 2003 Share slow from Server 2008 R2

Hello Experts,

I have a Windows Storage Server 2003 machine sharing a folder. This folder can be accessed from Server 2003 machines and XP machines very quickly. However, accessing this folder from any Server 2008 machines is extremely slow. It takes a quite while to browse through the folders and view it's contents. What could this be? I also ran a IO test to this share from the 2008 servers and it is getting less than 1 IOP which is extremely bad.

Thanks!

Try disabling tcp autotuning. This has to be done from an "Elevated" command prompt.
This is the command to run:
netsh interface tcp set global autotuning=disabled
If no changes, then you can enable it again.
And if the server has Broadcom interfaces, then you can try to disable tcp chimney: http://support.microsoft.com/kb/951037

Thank you. You pointed me in the right direction & after a reboot of the server I am able to browse much quicker.

Cheers!
