Microsoft Jet Database Engine error

[enigmaos]

Has anybody seen the error below?

I'm working on a login screen with VB.NET Web Application. I need to get data from Test.mdb (an Access97 database located on the network) and check the login/password. Test.mdb is being used by another application also.

Everytime, when the Web Form tries to fill a dataset (i.e. myDataAdapter.Fill(myDataSet, "tblLogin")), it just errors out with the error below.

The Test.mdb is shared and "Everyone" has FULL CONTROL permission.

What do I need to do to get rid of that error?

 Server Error in '/Project1' Application.
The Microsoft Jet database engine cannot open the file '\\Server1\C\Program Files\Test1\Test.mdb'. It is already opened exclusively by another user, or you need permission to view its data. 
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. 

Exception Details: System.Data.OleDb.OleDbException: The Microsoft Jet database engine cannot open the file '\\Server1\C\Program Files\Test1\Test.mdb'. It is already opened exclusively by another user, or you need permission to view its data.

NOTE: I tried to link just the login/password table on the local machine (where the Web Application is), and it still returned the same error message.
