Yesterday i had it working, today it breaks.. :( But at least i've turned on logging and can pass you the relevant section of the log ;) When i try to connect to the share 'web', NT throws an error 'The specified group does not exist' and refuses to connect. I'm using virtually the same smb.conf file; I've tried it without the first 3 lines in [global], same results.
