Does anyone know if file sharing to/from 10.8 from/to a Windows 7 system works?
Edit: I turned up a command that apparently "fixes" the issue in 10.7:
sudo sysctl -w net.smb.fs.kern_deprecatePreXPServers=0
So assuming that 10.8 still doesn't support SMB1 I can hopefully at least stick this command into an init filesomewhere so that Linux\Windows systems will talk to the mac again without much hackery.
I actually couldn't even get file sharing working between Mac's without using SMB, I've never managed to get AFS to work reliably but SMB\CIFS used to be pretty bulletproof.
