Slow Browsing of Network Drives in Vista

I've been noticing lately that when open my network folder connections, there is about a 5-6 second delay when browsing as it seems Windows Vista is searching the entire computer to "find" the already present network drive data. Attempting to click on folders or files that show up while its seaching seem to be delayed as well. Eventually, you may even get the "Windows is not responding" message. Our network domain is made up of mostly Windows 2003 servers so this may have something to do with it but I am not sure and I do not have access permissions to be able to troubleshoot this myself. So, is there a workaround for this slowness?

Of course there is......and yes I found it by using Google. Here is the answer, compliments of

Type in the following commands from the command prompt:

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

RSS stands for Receive side Scaling, not the other RSS.

Make sure you are logged on as an administrator when you do this. You will need to restart your PC for the changes to take affect and you will definitely notice the speed difference.

If for some reason you need to reverse the changes, type the following:
netsh int tcp set global autotuninglevel=normal
netsh int tcp set global rss=enabled

So if your browsing of network drives are slow, try the above solution to see if this helps. If not, get with your administrator to see if they have any other ideas.
