A family of Microsoft relational database management systems designed for ease of use.
I get this problem too. As far as I have noticed, it only appears when running Access 2007 on Windows 7 (not on XP for me, and I have tried to replicate it). I have tried changing network ports, cables etc to no avail. In my set-up, I have the database split, with both parts residing on the same server. I have googled extensively for soloutions but yet to find anything useful (although I did fix other access problems - like crashing when you open tables - by uninstalling the HP protect tools which HP install needlessly on new computers).
