netbios names and dns
RW 7/2/2007 8:54:02 PM
if I need to comunicate by mean on netbios names across networks with
firewall between them is there a way to do this without involving WINS?
I simple cannot resolve netbios names by doing nslookup going from stand
alone client or server that is not part of domain and not appending prmary
dns suffix...
i.e. nslookup server_name.domain does return IP
nslookup server_name does not

Yes, there is "a way" but if you wish to use NetBIOS across multiple
subnets then you have a PRACTICAL need for WINS Server* and
for every machine to be a WINS Client.

* Or replicated "set of WINS Servers".

NSLookup does NOT use NetBIOS methods at all -- it has its own
resolver.

For general resolution NetBIOS resolution MAY use DNS methods after
NetBIOS (broadcast, WINS, LMHosts) fails, but this is not efficient.

You must check the box in the WINS tab of the IP settings to get this
behavior.

This will NOT however cause things like browsing to work -- browsing
depends on NetBIOS (and WINS across subnets) as a "locator" or
"rendezvous" service for Master Browsers with the Domain Master
Browser and among differen Domain Master Browsers.

Nslookup appends the DNS Suffix search list it picks up from the DNS client
service, and will append only those suffixes.
If you need a different DNS suffix appended, you must configure a custom DNS
suffix search list that appends all suffixes you need.
