Hi Wayne,
To resolve this problem, you may perform the following steps.
1. Create "Secured.mdw" using "Wrkgadm.exe" for the access database. This
"Wrkgadm.exe" can be found at the following location: "C:\Program
Files\Microsoft Office\Office\1033". The following KB article described how
to create "Secured.mdw" using "Wrkgadm.exe".
305541 ACC2000: Understanding the Role of Workgroup Information Files in
Access
http://support.microsoft.com/?id=305541
2. Use MSDataShape Provider to grant privilege to Admin. The following is a
code snippet for demonstration, you can modify it to meet your reference.
oleDbConnection1=new OleDbConnection(@"Provider=MSDataShape;Data
Provider=Microsoft.Jet.OLEDB.4.0;Data Source=db1.mdb;User
Id=admin;Password=;Jet OLEDB:System Database=Secured.mdw");
oleDbConnection1.Open ();
oleDbCommand1=new OleDbCommand ("GRANT SELECT ON TABLE MSysObjects TO
Admin",oleDbConnection1);
oleDbCommand1.ExecuteNonQuery();
oleDbDataAdapter1=new OleDbDataAdapter("SELECT * FROM
MSysObjects",oleDbConnection1);
DataSet ds=new DataSet();
oleDbDataAdapter1.Fill(ds);
For more information, you may check the KB article:

Lewis
