good afternoon. Just set up my first server, using all defaults, and nothing fancy configuration wise. I can connect to the domain with windows machines, (both vista and Win7), but I cannot connect using a mac (OS X lion 10.7.4). On the mac, I get an error of "Authentication server could not be contacted. (5200)". This is a very small environment, and all of the machines are on the same subnet etc. I have little experience with Macs, so I'm hoping someone out there can point me in the right direction.
