Access database over 2X server

[abbers_01]

I am having some issues opening my Access database over the 2x server. The front-end of the database does open, however when it queries the usernames for the login page I get the follwoing error:
Could not use 'E:\db\mydb.accdb'; file already in use.

The file is in use by others using the database but should it not be able available for mulitiple users?

Any insights on this issue would be appreciated.

Frontends should be a COPY on your LOCAL machine, not on the server. The backend should be the only part on the server.
