DNS for Win2K (was: Win2000 "junk" in DNS)

[Don Buchholz]

I'm completely in favor of hearing more about this.  What I'm assuming
from this thread is that MS Active Directory is unable to work without
using underscores (_).

Now, as far as I know, the underscore has always been legal in records
such as HINFO, it just can't be used in hostnames -- i.e. on the LHS of 
an A-record or RHS of a CNAME, MX or NS record.

I guess the real question is:  Has Microsoft "embraced and extended" the
DNS specification so completely that an Active Directory server *must* be
used to supply DNS information to a heterogeneous corporate network?
