Question

I use advapi32.dll’s logonuser method to access data over our network.
I know it change the thread’s user to the information i give it, but i was wondering if there’s a way to reverse it.
I want to access the data and then return to the local user credentials.

Answer 1

Some time ago I created a small impersonator class.

Basically you wrap your code to execute under another user simply inside a using block:

using ( new Impersonator( "myUsername", "myDomainname", "myPassword" ) )
{
   ...

   <code that executes under the new context>

   ...
}

Worked very well for my projects.
