Solved! For anybody having this issue when connecting to windows 2000 / 2003 servers, I've found the solution! Upgrade your Windows 7 build to 7232 (can be found on many torrent and p2p sites...I got mine off of pirate bay). It's the "expected" build to be in the retail version, and I can happily say I don't have any more connection issues when connecting to multiple win2000 servers. Hooray!
