COM object that has been separated from its underlying RCW c

This happens when you have released the underlying COM object when it
is still referenced by another .NET object.

http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dno2k3ta/html/o
dc_OFComplexComObjectsPIAs.asp
provides a little information on how COM and .NET work together.

The reason this only happens on your server is that something isn`t
working as expected under load with multiple users, which is not
uncommon when using MS Access as a back-end.

You might want to try granting the NETWORK SERVICE user FULL CONTROL
permissions on the folder that holds the database.

You will also want to make sure you have the latest MDAC verision
installed on the server,
