I have a couple of nw65sp8 servers running named (v6.07.09) for my
primary dns zone.

Thought I read somewhere that dns servers should not have an underscore
(_)in their name, of course after I had built these servers.

Anyone know if this is true & I should rename these servers?

Couple weird things *do* happen w/ them. If I do an nslookup of a
local resource & do that lookup from one of these dns servers, I get
the following:

*** Can't find server name for address <dns server IP>: Non-existent
Server: UnKnown
Address: <dns server IP>

Name: <search string entered in nslookup>
Address: <IP address of requested service looked up>
