Are there problems running Microsoft.Office.Interop.Access on Windows Server 2003?

[Jason Hamilton]

Hey all,

I have written a Windows Forms application in VB.NET that creates a WCF Server. This server uses the Microsoft.Offic e.Interop.Acces s library to get a list of all of the MS Access Reports in a *.mdb file and returns that list as a List(Of String) to a client that is implemented in an ASPX page hosted on IIS on the same machine.
I built the project on my WinXP development workstation and am now trying to deploy it onto a Windows Server 2003 server. I can access most of the Interop library correctly, and the PIA is installed correctly. I get a problem on:

Public Function GetReports() As List(Of String) Implements IHarpWCF.GetReports
        Dim reports As New List(Of String)
        Try
            Dim accessReports As Microsoft.Office.Interop.Access.AllObjects
            accessReports = m_Access.CurrentProject.AllReports
            If accessReports.Count < 1 Then
                reports.Add("There are no reports in the database at " + m_targetDatabase)
            End If

            Dim iter As System.Collections.IEnumerator
            iter = accessReports.GetEnumerator()
            While iter.MoveNext()
                reports.Add(iter.Current.Name())
            End While
        Catch ex As Exception
            RaiseEvent ServerError(Me, ex.ToString())

        End Try
        Return reports
    End Function

The exception reads:
System.Runtime. InteropServices .COMException (0x800A09A3): The expression you entered refers to an object that is closed or doesn't exist. at Microsoft.Offic e.Interop.Acces s._CurrentProje ct.get_AllRepor ts() at Harp_WCF.HARP_W CF.GetReports() .

I expect that, perhaps, the issue is that the application is being run in a different user context on the IIS machine perhaps? Could there be a security issue with using the Interop libraries on Windows Server 2003? I'm kind of out of ideas since it runs fine on my XP machine, but I have to believe that there is just some hoop I can jump through to get it working on the server.

TIA,
Jason
