For some reason, our departmental server has stopped allowing me to connect to it via Screen Sharing. I get ‘Authentication failed to “SERVER”‘. I’ve tried creating a new admin account and connecting with that, but I get the same error. Everything else on the server is fine and I can connect to it OK with my account for file sharing, iChat, etc. I recently upgraded to 10.5.4 and rebooted but that made no difference.
Why might this have started happening for Screen Sharing? It’s extremely problematic as it means I can’t get a remote GUI on the machine any more.
