Hi, We've got Samba acting as our WINS server. All appears to be operating correctly except for a single NT 4 server which the WINS server won't resolve. - The server is NT4 Server with Exchange. - It does have the address specified in the network settings and is using the WINS server for its own resolutions. - There are wins.dat entries for this server. So why do I get: $nmblookup -U 10.0.0.1 -R server1 querying server1 on 10.0.0.1 name_query failed to find name server1 Thanks in advance, Leon... Fedora Core 2 2.6.5-1.358/Samba 3.0.4
