After unsuccessfully trying to join the domain several times using the win2k gui I consulted the logs. This is what I'm getting using "log level 3". tdbsam: getpwnam_alloc(mytest) return NULL. User does not exist! Is "mytest" there by mistake, or is this the correct variable. I have Samba 2.999+3.0.alpha20-2 Anybody? IRV
