title: Problem using AddIPAddress when impersonating an Admin User
body: <p>I am attempting to add a temporary IP address to a NIC using AddIPAddress when logged in as a non-admin user. The MSDN documentation for AddIPAddress states that ERROR_INVALID_HANDLE is returned as as error if the function is called by a non-admin user.</p>
  
  <p>Given that I have preceeded the call to AddIPAddress with API calls to LogonUser() and ImpersonateLoggedOnUser(). Now my application thinks it's logged in as an Admin, but AddIPAddress still fails with ERROR_INVALID_HANDLE.</p>
  
  <p>MSDN also states that..</p>
  
  <p>"Note  Group policies, enterprise policies, and other restrictions on the network may prevent these functions from completing successfully. Ensure that the application has the necessary network permissions before attempting to use these functions."</p>
  
  <p>Is it possible to call AddIPAddress using impersonation? if so how? I'm guessing I need to change the permissions mentioned above but I am at a loss as to what to chnage in this area.</p>
  
  <p>Any help would be appreciated!</p>
  
  <p>Additonal: I've also drawn a blank while attempting to call out to netsh (again logged in as a normal user) using CreateProcessAsUser using a handle to an impersonated admin user to launch the process. Always returns errors indicating insufficent priviledges.</p>
