User.IsInRole("Domain\Administrators") Error

[Glowworm27]

Arrrrgggggg......
ASP.NET --
Hi all, I got a bug in the VS.net IDE that is troubling me.

I am trying to determine if the user is in a group in the domain. I am using the User.IsInRole("Domain\Administrators&quot method to check if the user is a member of the Domain administrators group.

The problem I keep getting is, when I run the code in design mode, I receive an error ->

A first chance exception of type 'System.ArgumentException' occurred in mscorlib.dll

Additional information: Item has already been added. Key in dictionary:"Domain\Administrators" Key being added: "Domain\Administrators"

<- if I continue the code execution it will return true becasue I am a member of the administraors and works as I had hoped. My question is how do I get rid of the design time error? or am I doing something wrong?

I will include some code for you to see....

-------------------CODE-----------------------------

Imports System.DirectoryServices
Imports System.Web.HttpContext

Public Class multipage

Inherits System.Web.UI.Page


Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

lblStatus.Text = System.Web.HttpContext.Current.User.Identity.Name


Try
If (HttpContext.Current.User.IsInRole(&quot;TIRESPLUS\ISGRP&quot) Then
lblStatus.Text &= &quot; user is in ISGroup&quot;
End If
Catch ex As Exception
lblStatus.Text = ex.Message
End Try

------------------- Code stopped for brevity ----------
The designer throw the error when tring to execute the IF statement, however no execption is ever thrown...???

oh , running windows 2000 pro, Visual Studio.net 2003 professional not sure of any service patches installed.


Please help
Thanks
