I have spoken with some folks from Microsoft who swear up and down that
DNS-GlobalNames-Zones is not a replacement for WINS (In 2008) it sure
seems to me though that someone had some idea of a way to remove some of
the reasons to have WINS.

I will have to go read that, but I still don't see why they couldn't
create a
new NetBIOS name resolution Node-type, DNS, analogous (precisely)
to what they did when WINS (NBNS) was first released and nodes were
enhanced to eliminate the complete dependence on broadcasts.

SRV records now exist and there is no reason this couldn't even be
site specific (as an additional optimization, not the primary method) for
a cheap way to get DFS resolution too.

I'm using the AD Installation Wizard in Win2K3. The part of the DNS
name
before ".com" is longer than 14 characters. Is there any way to
override
what appears to be a 14-character limit to the NetBIOS name or must I
choose
a name that is different from the level two part of the DNS name?

No, because that limit (15 character's actually) is hard coded into
all NetBIOS
names which are at most 16 characters and which use the final
character to
represent different services (much as ports do in basic TCP or UDP).

[All NetBIOS names are padded out to 15 characters with spaces when
put
onto the network, then the 16th character is used to distinguish the
service.]

Just make up a name that is sensible for the NetBIOS name. The only
real
disadvantage is that people might become confused or be unable to
"guess"
the names from nothing the other one.

---------------------
Richard, Paul, Herb,

THanks to you all for your help. I've often wondered why Microsoft
cannot just dump the whole NetBIOS concept and use DNS like the rest of
the Internet and operating systems.

Because certain Legacy Applications and Operating Systems are still
based on
NetBIOS.

Most important for most people is Browsing which is a Legacy NetBIOS
application.


I can't see that the NetBIOS paradigm provides much that is valuable
other than, when combined with WINS, it gives users the ability to
browse based on broadcasting (or is it multicasting?)

Broadcasting for NetBIOS alone -- WINS helps to eliminate that since it
works similarly to DNS, using datagrams for registration and resolution
requrests.

which cannot be transmitted past certain boundaries such as VPN tunnels
anyway.

It is not the VPN per se that is the problem, but the ROUTERS which
typically are at either endpoint of the VPN.

By default, Routers don't transmit broadcasts.

Moreover, I'm not convinced that NetBIOS and WINS are the only services
which can enable "browsing" in Windows Explorer.

NetBIOS is since Browsing is a NetBIOS applciation.

WINS makes it work across routers.

Windows networking would be somewhat simpler certainly if WINS were
gone and I also would have no hesitation seeing the NetBIOS concept
gone.

Not particularly -- WINS is no big deal; mostly is SOLVES problems
although
the naive among admins seem to get this relationship backwards pretty
often.

I'd much rather log on to Windows domains specifying that I'm loggin on
to abc.com rather than to ABC.

That's is irrelevant to the Browsing and NetBIOS issue as the (modern)
systems
can now use DNS to logon (DC) discovery and to authenticate in general.

Feedback? Am I being naive here?

A bit. And you are placing the blame off-center from where it belongs.

The easy way to fix this stuff would be to create a new registration and
resolution
MODE for NetBIOS: DNS.

Resolution already works (partially) through FAIL OVER to DNS methods,
but
NetBIOS clients and servers have no concept of using SRV (or some other)
records for rendezvous and location service.

Thanks much,

David
