You name it, we got it.  Win 7, XP and 2008 R2 RDS.  SP 1 on 7 and 2008 R2. 3 
on XP. And I would say mostly Win 7.  Oh, and we got Ipad 2 but deep down I 
hope they break.

"  Because a CNAME must be the only Resource Record defined for a given domain 
name."

So SOA and NS are considered resource records? Because that is all that is in 
that zone.

nosslsearch.google.com<http://nosslsearch.google.com/>.

No www.google.com<http://www.google.com> in my record, that is the zone name.

  You can't have a Resource Record without a domain name.  It's simply not 
possible in the protocol.  When the GUI shows you the "zone", the domain name 
is implicit.  :)

  At the protocol level, zones don't exist explicitly.  They're a higher level 
construct, implied by the the existence of certain records.

Where you have your example record below change the left column to read 'same 
as parent folder' all the way down including the DNAME.

  Same thing.  :)  I was using the standard notation for DNS records, which is 
defined in RFC-1035 Section 5<http://tools.ietf.org/html/rfc1035#section-5>.  
It's sometimes called "zone file" or "master file".  In that format, if the LHS 
(left-hand-side) is blank, the LHS of the previous record is implied.

In addition to what you show I also have all my name servers in that record of 
course.

  Right, right.  I did leave that out.  :)

Actually, if you want to ask a question the one that is on my mind is why 
wouldn't it take the CNAME record when I wanted to add it. It seems to me it 
should have and that was the suggested solution. Over on another list some of 
the people are still scratching their head as to why it errored on me when I 
tried to add the CNAME...leaving the alias blank (same as parent folder) and 
adding nosslsearch.google.com<http://nosslsearch.google.com> for the target 
FQDN.

  Because a CNAME must be the only Resource Record defined for a given domain 
name.

  I explained 
this<http://www.mail-archive.com/[email protected]/msg109449.html>
 earlier in this thread.  :-)

2008 R2 integrated DNS.

  What Service Pack?

  What about the clients?  For example, are they mostly Win 7/Vista?  Or is it 
a typical school where anything can happen and often does?  :)

My problem was that other than the SOA and NS records I had no other records to 
remove. The behavior on this seemed to have changed starting with 2003 and up.

  See what I mean about depending on undefined (or invalid) behavior?  Then 
someones goes and fixes their code, and the thing you were depending on doesn't 
work anymore.  :-)

  Get me the story on the clients and I'll ask over on dns-ops.  I'm curious 
myself, now.
