Hi there, I have two Samba servers running within an NT domain. One Samba (F-Samba) server runs samba-1.9.18.10 on top of FreeBSD-2.2.8 and the other (L-Samba) runs samba-1.9.18p2-C6 on a RedHat Linux variant. All of our NT machines run NT4,SP4. One is workstation and the rest run server. The PDC is an NT Server (NT1). F-Samba and L-Samba only show up in the browsers of about half of the NT machines, not including NT1, the PDC. Running "smbclient -L F-Samba" on L-Samba or "smbclient -L L-Samba" on F-Samba produces accurate results in both share information and interface information. Running "nmblookup '*'" returns only those NT machines that can see the Samba servers. Running "nmblookup -M" gives a name query error. Running "nmblookup -S -B NT1 '*'" i get a name query error even though the query was sent to correct IP address. However, running "nmblookup -S -B NT2 '*'" another NT Server it returns with 10 names including "..__MSBROWSE__." This might be due to our NT administrator playing around with the Master Browser settings. I'm not clear on what he did exactly. He's studying for his MCSE so he not around for me to ask. I looked around on the website and noticed BROSWER-config.txt recommends using only one protocol since NetBIOS can run over both IPX and IP. Interestingly enough, the PDC NT1 runs only NetBUI and TCP/IP. NT2 runs NetBUI, TCP/IP and IPX. I was hoping there would be a hard and fast correlation here but it isn't the case. Some NT machines that run IPX don't see the Samba Servers and some that don't run IPX see the Samba Servers. Here are some excerpts from testparms of both Samba Servers. F-Samba ======name resolve order = lmhosts host wins bcast os level = 0 preferred master = No local master = No domain master = No guest account = nobody guest only = No guest ok = No L-Samba ======os level = 0 preferred master = No local master = Yes domain master = No guest account = nobody guest only = No guest ok = No So, does anyone have any ideas on this one? Thanks. john
