The problem seems to be related to the new version of 'System/Library/Core Services/AppleFileServer'.
If you can get hold of the previous version (3.1.4) and replace the new (3.1.5) version (don't forget to fix permission when done replacing) the problem goes away.
This is a lot easier than trying to downgrade the server or do a reinstall.
I've done this to 3 servers with positive results so far. Even our old MM users can connect again!
