This may be known, but until very recently I have not found the solution anywhere online, and the problem of not being able to connect to my Lion MBA via VNC has been driving me nuts since about DP2 o3 DP3.



I found a workaround the other night and wanted to share it:



On your Mac, log out of your user account. You will now be able to connect via VNC from Windows, and probably any other non-Mac platform.



Apparently being logged out first allows the VNC client to make the connection without having to run into the new multi-user connection functionality of the Lion server. I'm sure that VNC clients will update before long to deal with that, but until then, this works perfectly.



Keep in mind that if you disconnect the remote session without logging out of the Mac account first (remotely, of course) you will not be able to reconnect until you go to the Mac and manually log out again. A small price to pay for the otherwise full VNC functionality.
