SOA needed in subdomains?

I have domain set up, site.com, I wanted to add a subdomain to it. So I
added a new domain to the site.com domain. The only records I can add
to that new domain which appear to be any good to me are the <a> records.

So, I added my <a> record and gave it a IP address which is internal to
my network.

When I type the new address in a browser, etc it can't find it.

If I add the <a> record under the site.com domain with the internal IP,
it works every time.

What's going on?

Thanks,
Steve

For a sub domain to resolve, you have to create a host record leaving the
name field blank and giving it the IP you want it to resolve to.
 
No, not if you mean a 'subdomain' as defined by the MS MMC
where it is PART of the parent domain zone -- there is only one
zone so there is only one SOA in the file/record set.

If you mean a subdomain with it's own child DNS zone then, Yes,
there will be an SOA in each separately delegated child zone file.

You cannot add a CNAME? MX? Or TXT record? etc.?

Something is wrong. What happens specifically when you right click on
the zone, subdomain and choose New "xxx"? Are they all greyed out?

Go to the command line and use NSLookup to specifically query the
nameserver.

Are you typing: recordname.subdomain.site.com?

You might have left the host name blank so that it would be just
"subdomain.site.com" but then there would be little reason for
a subdomain IF you only wanted to add records with this same
name (and not more records within the subdomain.)

nslookup FULL_NAME_YOU_ADDED IP_OF_DNS_SERVER

(copy and paste the output to your reply here so we can see it.)

Gives us all the names involved -- and make sure you are adding
or leaving out names you actually used in the MMC.
