I have a couple of Access adps which users are accessing through Citrix (sits on top of terminal server).

One of the adps gives an error everytime there are more than 1 users trying to access it:
The Database 'DB Name' will be opened read only because one of the following occurred:
the file is locked for editing by another user, or the file (or the folder in which it is located) is marked read only, or you specified that you wanted to open this file read only.

The other adp doesn't.

The permissions on the file/directory are the same between the 2 different adps.

The problem is not that the database is being opened read only, as the data in the SQL backend can still be updated, but rather that the error keeps popping up everytime someone uses it.

Does anyone know how I can stop this error from coming up? Users are finding it very off-putting.

Thanks in advance for any help.

Forgot to mention - am using Access 2k
