Do you see any unusual slowness if you enter

  $ dir \\servername\sharename

or

  $ dir \\servername

Note that the second should fail, but I'm interested in how fast it fails.

I'm still not so sure about the WebDAV stuff not being an issue
(kb/832161)...

Might be time to fire up wireshark and have a look at the messages
exchanged.

BTW, may I ask you to add your replies underneath the message you are
replying to? (No top-posting).

FWIW, I'm not really a fan of putting repositories on windows shares.
I'm just puzzled that people apparently still keep trying doing it.
