Downloading to a Vista Network Share

[rezen]

Hi!

My download folder is on a network share hosted by a Vista Ultimate (32x) machine.

I have utorrent running on both XP and a Server 2003 machines downloading to a mapped drive of the network share(hosted by Vista).

This setup was working fine when the shared folder hosted by an XP machine, now when it's shared by Vista, the torrents periodically fail and cause the network share to become inaccessible.

I already tried the following with no success:

1) Disabled Vista Network Auto-Tuning on the vista box

2) Disabled all protocols except IPv4 on the vista box

Any ideas what's wrong?
