Problems with ADO.NET and Access Database

I have an ASP.NET intranet site that needs to read the usernames and passwords from an Access Data base. The code is

<%@ Page Language="VB" %>
<%@ Import Namespace="System.Data.OleDb" %>
<%@ Import Namespace="System.Data" %>
Sub login_avotus(Source As Object, E As EventArgs)
dim rs,cn, dbpath, entity,rs2,temp_string
dbpath = Server.MapPath("\Avotus_Data\PMD003.mdb")
Dim myconn As New OleDBConnection("Data Source=dbpath;Provider=Microsoft.Jet.OLEDB.4.0;User ID=Admin;")
myconn.open
Dim myAdapter as new OleDBDataAdapter("SELECT * FROM Attributes WHERE pCode='LGIN' AND Value = '" & User_Name.Text & "';", myConn)
Dim myDataSet as DataSet = new DataSet()
myAdapter.Fill(myDataSet,"Attributes")
if myDataSet.Tables("Attributes").Rows.Count <=0 then
lbl_status.Text="Username is invalid"
User_Name.Text=""
Password.Text=""
exit sub
end if
entity = mydataset.Tables("Attributes").Rows(0).Item("pEntityID").toString()

Dim myAdapter2 as new OleDBDataAdapter("SELECT * FROM Attributes WHERE (pEntityID=" & entity & " AND pCode='WPWD') AND Value='" & Password.Text & "';",myconn)
Dim myDataSet2 as new DataSet()
myAdapter2.Fill(myDataSet2,"Attributes")
if myDataSet2.Tables("Attributes").Rows.Count <=0 then
lbl_status.Text="Username and Password do not match"
User_Name.Text=""
Password.Text=""
exit sub
end if
end sub

When I supply a username and password in my webfrom I get the following error message when I try to open the database


Line 15: dbpath = Server.MapPath("\Avotus_Data\PMD003.mdb")
Line 16: Dim myconn As New OleDBConnection("Data Source=dbpath;Provider=Microsoft.Jet.OLEDB.4.0;User ID=Admin;")
Line 17: myconn.open
Line 18: Dim myAdapter as new OleDBDataAdapter("SELECT * FROM Attributes WHERE pCode='LGIN' AND Value = '" & User_Name.Text & "';", myConn)
Line 19: Dim myDataSet as DataSet = new DataSet()

Any thoughts, I have given the Everyone group and ASP.NET account full control to the directory on the server. It works on my test machine(I have a copy of the Database file on my test machine) but, not on my server. Using ASP.NET v1.1.4322

Thanks,

This sounds similar to a problem I'm having. Did you ever get it figured out?

Have you checked the web.config file? On the server it is setup much differently than it is locally.
