The Master will only pass to DNS exactly what you type, in the order

 - does it look like an IP address => use it
 - can I find it listed in my static hosts list => use it
 - does the DNS server (if there is one) know about it => use it
 - otherwise error

See above.

Right, we're getting confused here between protocols.
Ping (ICMP) just needs an IP address so if you give me something I can
resolve to an address you can ping it.

Lanman (SMB over NetBIOS) needs an IP address, and a NetBIOS name to set up
a session. To get this some more messing about is needed

 - try asking everyone if the thing after '\\' is their name => use it
 - does it look like an IP address => try doing a reverse lookup then
                                      go back to step 1
 - can I find it listed in my static hosts list => try reverse lookup
 - does the DNS server know about it => try reverse lookup
 - otherwise error

now I have a NetBIOS name and IP address and can try to connect.

In (a) and (b) nothing is responding by any means listed above. In (c) the
server name you have given is longer than 15+1 long so is faulted. The 'Bad
name' is not referring to hitting a limit on the command length, but hitting
the limit of NetBIOS workstation name.

It should work, but I only have access to one Win2k machine and it's not on
a domain so we may need to do some off-list packet sniffing to get to the
bottom of this,
