Screen sharing not working Lion Server
I can't connect to my Lion Server from any other Mac. I got it working for a few minutes after the first restart but I can't get it to work now. It's a Mac mini server runnning headless. I've even tried connecting it to a TV for a screen and it looks like everything is still set correctly for screen sharing under remote management. I can connect via the Server Admin app (pretty slim compared to 10.6) and via ssh fine. Services seem to be running OK.
For the life of me I can't see what the problem is. It worked fine under 10.6.8 before upgrading.
