Linked tables in MS access used by IIS problem

Situation:
Got a Web-server running IIS. On the local disk got an mdb-file with 2 linked tables to two other mdb-files (tables) located on another server (file-server).
In an ASPscript I'm connecting to a query; this query has information of a table in the local mdb and the 2 linked tables.
Problem: the webbrowser (on a client machine)errors saying the specified drive of the linked tables is not correct.
Tried to fix this by setting up the to remote mdb-files as ODBC's; but the local access won't let me link via ODBC to it.

Anyone a good idea how to solve this?
Thanks,
Toto.

If you are using drive letters for your linking (D:\, E:\, etc.) that could be the problem.  Use server names, if possible.

PHL,
Thought about that too but getting a permissions problem on the page now:
 Microsoft JET Database Engine error '80004005'
The Microsoft Jet database engine cannot open the file '\\server\directory\datafile.mdb'. It is already opened exclusively by another user, or you need permission to view its data.

The datafile.mdb file is the original table; so basically the link works but now getting permission problems.

Any ideas how to work-around or solve this?
Toto.

Datafile.mdb is on the webserver and now your ASP page connects to it with a connection path that uses server names instead of file letters.  That is good.  Datafile.mdb has two linked tables that refer to a database on another server (file server).  These links should also use server names instead of file letters.

You should also check to make sure you can access the database on the file server directly.  Also, is there any chance it is actually opened exclusively by another user?  This also occurs if any object in that database is in design view.  Is there any possibility of moving that database to the web server?  If the linked tables are read only and updated infrequently, could local copies be imported?

Phl,

Sorry for the late reply.
No - moving the applications/database to the web-server is not an option.
But I made a small program that is importing the needed tables.

Other and related issue with this is the size of the mdb-file. When importing these tables; the size of the mdb-file is (of course) getting bigger and bigger.
Is there a way I can compact the mdb-file automatically (via code or macro)?

Cheers,
Toto.

The Access Web has some code to compact a database:
http://www.mvps.org/access/modules/mdl0020.htm

It should be done when no one is using it.
