Since I can't find thousands of other users reporting this I'm thinking it's got to be something wrong with my system, but after I updated to Mountain Lion I can't connect to Apple file servers anymore.
Not even a Drobo FS.
The servers still show up in my sidebar but they never successfully connect.
I tried creating a new user and connecting from that one, but still had the same problem.
The OSX servers are running 10.6 & 10.7.
Really? No one else is having this problem?

It seems that obsolete iDisk settings in OSX 10.8 may prevent you to connect to a file server.
You need to run those commands in Terminal
to get rid of those settings.
