Sometimes when connecting to a screen sharing machine in Finder, the authentication dialogue hangs indefinitely. The only way I've been able to get rid of it is log out.

So far I've tried killing a number of processes including:

  • Screen Sharing
  • Finder
  • Dock
  • SystemUIServer

To no avail. Any idea what process this UI is attached to?

Yes, it's called NetAuthAgent.

You can tell I've had this problem before! :(

+1 Yep, Me too! Mine seemed to be related with not being able to contact a remote machine via its name, e.g. mac-mini.local, only using its IP address. – binarybob Mar 24 '12 at 22:45
Those stuck Screen Sharing auth windows have been driving me crazy forever. Thank you so much! Now if I could only get Screen sharing to actually connect reliably... – ziggurism Jun 2 '12 at 3:48
