Ok here is the problem (not even our programmer is much help) I have a access program (database) that worked fine with access 97, I converted the database friday to 2000 and now everything that is linked to a .dbf file gives me this error "The Microsoft Jet database engine cannot open the file 'G:\DBASE\OWNEROP.DBF'. It is already opened exclusively by another user, or you need permission to view its data." Ok again I stress nothing changed on the network, and it still works fine with the 97 version. Any help with this issue is greatly appriciated, (the database resides on an NT 4 server)
