We determined that the problem was actually with the Antivirus software we use. In the settings there was a "Protect Network Drives" option that was enabled by default. Apparently this conflicts with the way Office 2007 handles network shares. Disabling the option resolved the issue for us on both XP and Vista computers, so I would recommend checking the antivirus settings :-). Hope this helps.
