This is not a QuickBooks data file or it is damaged

We moved a QB file from a NT 4.0 server to a Win2K server. When the Win2K workstations try to use the file while our Win 98 users are using the file we get the message "This is not a QuickBooks data file or it is damaged". If the Win 98 users log out of the QB file, the Win2k boxes can use the file just fine.

Proven facts:

The Win98 boxes use the QB file just fine with no problems on either server and with other Win 98 boxes logged in to QB. The Win2k boxes use it just fine on either server with as long as the Win98 users are out. All of these stations can use the file at the same time on the old server.

I have a similar problem. My office has a network server that contains all of the company files. My boss wants to upgrade all of our old WIN98 local machines to WIN2000 but after I installed QUICKBOOKS 2004 PRO to the WIN2000 machines, I could not open files that were also opened on WIN98 computers at the moment. The QUICKBOOKS files are located on our network server and is available to every computer in our office. The same error alert window showed saying "___.QBW is not a quickbooks data file or it is damaged." When the persons on WIN98 machines logged out of the file, the WIN2000 machines suddenly gain access to it. Does anyone know if everyone can access the quickbook files if all the machines accessing it were upgraded to the same operating system? More specifically, if I upgrade all the machines to WIN2000, will all of them be able to use the .QBW file on our network simultaneously?

The data file can be shared with PCs using Win-98, W-m2000 ans Win-xp. The PC users for 2000 and XM MUST be power users. Also check the domain to verify that it does not limit the file to one user.
