I have a vb.net application which runs fine when
installed locally on a user machine but when the
application is run from a network drive a security
exception error occurs. I've set the intranet zone
through the .Net Configuration wizard to Full Trust and
the app still has a security exception. I've turned on
Just in Time Debugging and noticed the security exception
is happening at that below line of code.

Dim rs As New ADODB.Recordset()

Any help would be greatly appreciated.

Have you tryed to download the latest MDAC from microsoft at
http://www.microsoft.com/data/ and installing that... you will probably
find for some reason the ADO is damaged or possibly you might like to try
ADO 2.8

Thanks for the help about the version of MDAC. If you
don't mind I have another problem that's happening since
the ADO part is fixed. Below is another security issue
I'm have when executing the application from a network
drive

An unhandled exception of
type 'System.Security.SecurityException' occurred in
system.windows.forms.dll

Additional information: Security error.

The line of code where it errors out at follows:

Private Sub frmMain_Load(ByVal sender As Object,
ByVal e As System.EventArgs) Handles MyBase.Load
Dim frmMainMenu As New frmMainMenu()
'Try
gForm = Me
frmMainMenu.MdiParent = Me
frmMainMenu.Show() <----THIS IS WHERE THE ERROR IS
'Catch Ex As Exception
' MessageBox.Show(Ex.Message, "",
MessageBoxButtons.OK, MessageBoxIcon.Error)
'End Try
End Sub
