When the database is closed (probably will be since you can't open it;^) check to see it a file called xxfile.ldb exists in C:\Program Files\MBRMS\.  If it does, delete it.  You may need to reboot to delete it.

If you still cannot open the file check the security settings and share seltings.  

For databases on network computers, go to the level that is shared.  Usually that is an entire drive.  Right click on it and select "Sharing and Security". Make sure "Share this folder" is selected and there is a  share name that does not have a dollar sign ($) behind it in the drop down box. (The dollar sign share is a default share for administrator only.) IL there is not one, add it. Select a share without a dollar sign. Select permissions.  Make sure the users that will be using the DB have change and read permissions.  

Then right click on the folder(s) that contain the database(s) and select "Sharing and Security". Select security. Make sure the users have read, write, modify, and read & execute permissions. Select advanced. Edit the users that will access the databases. Make sure they have create files and delete permissions.

Corrupt Microsoft Access MDBs FAQ
Chris BRetiredCommented:
Often when a second user can't open a single db, it can be solved by - going to the pc who can open it. Open Access and navigate to the db in question. click once to select, then click the drop arrow next to Open, and select Open from the list. This will remove the exclusive, at least temporarily. Best solution is to create a front for each user, and a backend to share. Generally this solves all such issues.

Price Your IT Services for Profit

Managed service contracts are great - when they're making you money. Yes, you’re getting paid monthly, but is it actually profitable? Learn to calculate your hourly overhead burden so you can master your IT services pricing strategy.

Chris makes a good point.  When you get that message, is someone else using the DB?  Nico & I assumed no, Chis Assumed yes.
I vote for a three way split.  They are all good answers for the problem.
