Actually, "..only 5 or 6 people.." is untrue.
Every CSS engineer has the tools available to them to write KBs.
Additionally, every product team member has access to these as well and
all of them are strongly encouraged to make their knowledge public
through KBs, whitepapers, TechNet, etc., etc.
It's the same argument.
Name collisions cannot occur if:
1. WINS doesn't exist or is built properly (replication, etc.)
2. DNS structure is built properly
BTW; I'm "from Microsoft"...

-------------------------------------------------------Hi Jim,
I agree with you and I do find technet article's that are unclear and
are
missing steps, however much of it is, that Microsoft has only 5 or 6
people
creating that content and probably do not always test ( Or have very
limited testing ) what they are listing.
However, this section below makes a lot a sense. If you have a very
flat
domain, you probably would not have an issue. But if you have a large
World
Wide enterprise such as Microsoft, Cisco, Intel, Ford Motor Comany, GM,
etc,
with a very complex network and many DNS sub domains and childs, this
may
be an issue.
( Please read this sections )
" Name collisions cannot occur when you use WINS. In a WINS environment,
only one computer can be named SERVERA. In DNS, multiple computers can
be
named SERVERA. For example, one computer may be named
SERVERA.EUROPE.DOMAIN.COM and another computer may be named
SERVERA.AMERICA.DOMAIN.COM. If a user who is located in the AMERICA
domain
types \\SERVERA, they connect to SERVERA in the AMERICA domain. If a
user
who is located in the AMERICA domain wants to connect to SERVERA in the
EUROPE domain, that user must specify the fully qualified domain name
(FQDN)
SERVERA.EUROPE.DOMAIN.COM. Some programs may only permit entries with a
maximum of 15 characters for NetBIOS names. These programs may still
work if
a mechanism exists to avoid duplicate host names and if the DNS suffix
list
of domains is provided to all clients."
Any one from Microsoft care to comment on this?
Jose :-)
