You should check your Samba logs to figure out what is went wrong. If there are no issues then you should try updating your client to the latest and stable version.
got a 10. 1 (5G64) update CD, co I wiped my OS X partion,reinstalled 10. 0 and immediantly updated it to 10. 1. To get my smb/cifs shares back up, I reinstalled samba 2. 2. 1a from http://xamba. sourceforge. net. it installed find,but I am unable to connect. When running "top" from a terminal windows,i see that smbd is running, but nmbd is not.
