A client has recently upgraded from Office 97 to Office 2K. The access database that they use works fine on a single computer. As soon as they move it to a network file server, it gets corrupted every few hours (only 1 user is connecting to it in this case as well.)

They have tried connecting from different computers to rule out dropped packets from NICs. They have disabled opportunistic locking on the server. What course of action do you recommend we take next?
