I have split Microsoft access database that is being used by multiple users at a multiple locations. I have a login screen that comes on when a user first opens the database. We are all using the same version of Access. For every user but one it is working perfectly. For that one user if they click on the combo box to select their location or click the login button, they get an error that says "Not a Valid File Name". I have more than 30 users of the database but it is only this one user that is experiencing this issue. I am utterly lost to know what is causing this error or what makes this user unique.
We checked to make sure she had read/write permissions on the folder where the backend of the database is located, by having her open and save a text file in the folder and that worked fine. I even moved a copy of the front end into that folder and had her try to access it from there and she received the same "Not a Valid File Name" error. Then I attempted to login to that same copy there and did not receive that error it worked fine. Is there anything in the database that could be causing this error or is it a permissions error or maybe a firewall error?
