Microsoft Access produces error message when trying to open 2 dbases

[lancergsr]

If user has an access database open and tried to open another one, the second database tries to open, the access shell opens up but give the error "not a valid file name"

any ideas what could be causing this??

It is probably from UNC, I believe this is how we fixed a similar problem.

Open up regedt32 and set up a registry key as follows:
HKeyCurrentUser\Software\microsoft\Office\Access\Options
Add the key "DontUseUNC" as a DWORD value and give it a value of 1.

This should fix your problem.
