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).
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.
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.
Any help would be greatly appreciated!
The issue was that the process was running as Administrator. Impersonation will not work because WNetAddConnection2 evaluates on processes user. You must start a separate process to accomplish this.
