[Daniel Tan]

The difference is that the DNS doesn't resolve the NetBIOS names and the
WINS does. Back in NT system it was possible to integrate DNS into WINS and
non-NetBIOS hosts could query Windows NT DNS server for names in the zones
that use WINS lookups. W2k network can be configured without NetBIOS
utilization, hence without the WINS.

DNS uses Fully Qualified Domain Names (FQDN) with "dot notation". DNS is
routed and directed (not broadcast-based).

WINS uses a flat namespace with single-word names and no dots. It is based
on Netbios non-routable, broadcast-based technology. WINS is just a server
that holds a Netbios Name listing to help hosts overcome the non-routable
issue so they can resolve names from across subnets

DNS compares to the old "Host" files, while WINS compares to the old LMHosts
files.

Phillip, do you mean that dns is routed in terms of resolving names ?
do you mean like resolving name using caching and zones ? i was
referring to netbios name resolution. btw dns should be more efficient
then wins, right ?

No. I mean it is "directed". The client makes a request to a "specific" DNS
Server,...it is a directed request made directly to a certain DNS. This is
totally different than Netbios Naming where is is all done by "broadcasts",
because it is broadcast based it cannot cross routers and Netbios isn't a
"routable" protocol.

WINS overcomes the weakness of Netbios by creating a centraized location for
Netbios Names information and the client can access the WINS Server in the
same directed way that they would for DNS and therfore this allow Netbios
Name to work across Router when otherwies it couldn't.

I think that it would probably be one of those things that ends up just
being opinion as to which is more effiecient, I'm really not sure myself.
