Windows 7 + Sharepoint UNC = SLOW
Upgraded to Windows 7 and almost everything is great. One problem that I've been unable to resolve though is that accessing Sharepoint via UNC path from this OS is EXTREMELY slow.
This isn't a network problem, and it's not a server-side performance problem. How do I know? Well ponder these facts:
1. The XPMode guest running inside the Win7 host can access exactly the same UNC paths very quickly by comparison, at the same times.
2. The server is fast via UNC for all XP clients and very slow for the same operation for all Win7 clients.
3. Caching on the server side isn't affecting these results -- it doesn't matter which guests go first, XP is always much faster than win7 when accessing sharepoint via unc path.
How big is the problem? Well it can literally take 30 seconds to open a folder on win7 that takes less than 1 second on xp. It doesn't *always* take 30 seconds -- sometimes it's only 5 or 10 seconds -- but it almost always takes much longer on win7 than on xp.
This problem does NOT extend to accessing sharepoint via web browser -- that works fine from both XP and Windows 7.
It doesn't seem to be a difference between 32-bit and 64-bit win7. I'm on x64, but I've tested several 32-bit clients with the same results.
Any ideas? Can anyone replicate this?
Note that I'm only talking about SHAREPOINT unc paths, NOT "normal" file shares. Accessing c$ on the server from either client is fine.

someone also suggested this
After wasting so much time installing Vista SP1 and hotfixes, which totally have no help at all to the problem, I finally found the right solution.
To those who had the same problem, try changing your network adapter from 100mbps full duplex (mine is default originally) to Auto instead. That solved the slow access problem right the way.
This setting should be changed under the device properties via Device manager.
1) Right click on "Computer" under the start menu and select "Properties".
2) Under the "Hardware" tab, Select and open "Device manager"
3) Click the plus sign next to "Network Adapters"
4) Right click on your NIC and goto Properties
5) Click on the "Configure" button. Choose the Advanced tab, and look for an item that mentions "Duplex & Link speed". Change it to "Auto".

Thanks, guys, but neither of those actually helps.
The duplex is already set to auto (and as I said, this isn't a physical network problem), and there are no speed/duplex-related errors on the clients or switch ports.
I did try all the other suggestions in the threads linked, but none of them had any impact either.
Does anyone else out there have a sharepoint site they can access via unc from win7 in order to confirm what I'm seeing?

I'll add these additional symptoms that I have noticed:
If I use the cmd shell to access the same sharepoint UNC paths from Windows 7, it's as fast as it is in the XP client. In other words, if I do this (where "teamworks" is the sharepoint server name):
Start > Run > cmd
net use z: \\teamworks\share
z:
dir
...then the directory listing comes back quickly (1 second).
If I then do "start .", Windows Explorer pops up and again takes a very long time just to complete the directory view (20 seconds or so).
Thus this problem so far seems to be specific to windows explorer. :-(
