The workgroup information file is missing or opened exclusively by another user.



I have a C# application that's been deployed to dozens of users over
the past couple years. It utilizes a password-protected MS Access
database with no workgroup file via the following connection string:

Provider=Microsoft.Jet.OLEDB.4.0;
Data Source=(path to my db);
Jet OLEDB:Database Password=(my password);

Recently, one installation of my application that has had no problems
for months started randomly throwing the "The workgroup information
file is missing or opened exclusively by another user" error message.
The user has successfully repaired the database using my app (which
uses JRO via interop), but the error eventually returns within hours.

Because this is only happening on one customer's computer, and it
appears to be happening randomly, I'm not sure where to go from here.
Any suggestions would be greatly appreciated. Thanks in advance!
