When the application is executed with run as administrator it fails to find files on a mapped network drive using FindFirstFile. If the executable is run without run as administrator is works. The user is a local administrator on the PC. When FindFirstFile fails the error is 3, ERROR_PATH_NOT_FOUND. Is running as an administrator changing access rights or my access to the mapped drive?
I'm testing on a Windows 10 PC with a domain user that is a local administrator. Application was built using VS 2010 on the Windows 10 PC. Application is a native c++ app. I've turned off the firewall, still fails. Turned off Windows Defender, still fails. Recreated share and mapping, still fails. Ideas?
Network drives are mapped per-user. If you map a drive as your user, but run your application as Administrator, the network drive won't be mapped from the application's perspective. To get around this, you can map the drive as Administrator by opening an admin command prompt (right-click cmd -> run as Administrator) and run net use F: \\path\to\my\share.
