title: WNetAddConnection2 in Windows 7 with Impersonation and no Error Code
body: <p>I'm doing some crazy impersonation stuff to get around UAC dialogs in Windows 7 so the user does not have to interact with the UI (I have the admin creds of course). </p>
  
  <p>I have a process running as the Administrator and elevated past UAC. The issue that I'm facing is that when I make a call to WNetAddConnection2, within this process, I am not getting a new mapped net drive. The function returns ERROR_SUCCESS but no net drive is visible. We have another method of adding network drives using 'subst' but this, again, returns successful does does not add a net drive. I have tried to use the default user (which is the Administrator because of process's security context) and I have tried using specific user credentials. I can map the drive just fine through Explorer. </p>
  
  <p>Of course the same functionality works fine in XP/2003.  I haven't got around to testing on Vista because of issues with impersonation that are limiting my ability to spin up the process.  Are there unique Windows 7 limits on this function? MSDN does not glean any that I can find. </p>
  
  <p>Any help would be greatly appreciated! </p>
