I've got a Samba 3 box running RHEL 3 that has been added to a Windows 2000 domain as a member server, however it cannot be browsed via the network (it appears within the domain, but does not open the machine). Its IP address is 10.30.4.1/255.255.252.0, nbtstat.exe on one of the windows boxes returns as below P:\>nbtstat -A 10.30.4.1 Local Area Connection 3: Node IpAddress: [10.30.5.1] Scope Id: [] Host not found. DNS is used for name resolution and Ping can resolve a name to an IP address. Smbclient can connect to another host however nmblookup cannot. Smbclient when directed at itself does not detect the master browser. [root@testlab-route samba]# smbclient -L router -N Anonymous login successful Sharename Type Comment --------- ---- ------- delta Disk Delta Testing IPC$ IPC IPC Service (Samba Server router) ADMIN$ IPC IPC Service (Samba Server router) Anonymous login successful Server Comment --------- ------- ROUTER Samba Server router Workgroup Master --------- ------- DEETTEST Broadcast pings only return a response from the machines own IP address. Additionally, while 'net ads join' completes without issue, 'net ads info' reports as follows: [root@testlab-route samba]# net ads info Didn't find the ldap server! Thanks in advance.
