C# webbrowser control and impersonation

Hi friends

Background of my question is a monitoring solution (SCOM) that I have to provide for others in the department.

I like to have the possibility that I can see the same what the other employes of each usergroup can see. As I'm working with more rights as the others I always have extra work that I can see what they with the limited rights can see.

I'm like to create now a small application (winform) that allows me to observe the webpage for all of the different groups in a single application with all the different point of views. All the resultsets are on the same webpage but are different for the users.

What I like to do is:
- creating an application with a tab for each usergroup.
- configure for each usergroup a "dummy" account that has the same rights as the users of the group (in fact is a member of the same windows group)
- now create a webbrowser control and using the credentials of the dummy account

Solution that I have in mind:
- creating an usercontrol that will take in the constructor the URL, the usernamen and the password
- on runtime read the configurations and create for each of the items a tab with the usercontrol

Problem:
How can I create the usercontrol in a different security context?
I was trying to use the UriBuilder with username and password but the result was not working at all.

Has anyone an idea?

best regards
Dirk

Combine code from 2 links:
Accessing Password Protected Network Drives in Windows in C#?
A complete Impersonation Demo in C#.NET
And do folowing steps

C#

//1. Logining
IntPtr token;
IntPtr tokenD;
if (!NativeMethods.LogonUser(login.User, login.Domain, login.Password, LogonType.Interactive, LogonProvider.Default, out token))
    throw new Win32Exception();
if (!NativeMethods.DuplicateToken(token, SecurityImpersonationLevel.Impersonation, out tokenD))
    throw new Win32Exception();

//2. Profiling. You nead administranor or local account to run LoadUserProfile
ProfileInfo profileInfo = new ProfileInfo();
profileInfo.dwSize = Marshal.SizeOf(profileInfo);
profileInfo.lpUserName = login.User;
profileInfo.dwFlags = 1;
if(!NativeMethods.LoadUserProfile(tokenD, ref profileInfo))
    throw new Win32Exception();

//3. Impersonating
var identity = new WindowsIdentity(tokenD);
var context = identity.Impersonate();

//5. Create Browser
var browser = new WebBrowser();
browser.Tag = context;
browser.Navigate(new Uri("http://www.codeproject.com"));

//6. Dispose after user, can bee on WebBrowser.Disposing or try it on tabs Selection event
NativeMethods.CloseHandle(tokenD);
NativeMethods.CloseHandle(token);
NativeMethods.UnloadUserProfile(tokenD, profile.hProfile);
context.Undo();

Its old question. Maybe you have another solution? If so, please post it.
