dns issues

not necessarily linux, but more of a 'general unix dns' thing:

Im having a problem of sorts with dns at a place where I cannot control 
the dns servers (believed to be winNT or win2000).

I've done alot of research trying to figure out what the problem is and I 
believe I have the answer.  Im pretty much just looking for a "yeah, thats 
the problem (from experience)" or "nope , thats completely wrong" 

scenario:

 an internal dns server doing dns for all internal clients.   an all 
windows shop except for our 2 sco boxen (SCO_SV hostname 3.2 5.0.6 i386).  
using an outside dns server, I can query the given domain name, however, I 
get their outside IP address, not the inside one (which we need).  I can 
do a nslookup on mail.domainname.com no problem, but on domainname.com I 
get non-existent host/domain.

  from 2 sco boxen, I do a nslookup for a domain name:

------------------------------
ads@domain:/u/ads>nslookup
Default Server:  dns.domainname.com
Address:  192.168.1.16

> domainname.com
Server:  dns.domainname.com
Address:  192.168.1.16

*** dns.domainname.com can't find domainname.com: Non-existent host/domain
-------------------------------

however, the admin of the dns servers swears that from all her win boxen 
this works fine.  so I do more research.

-----------------------------------

ads@domain:/u/ads>nslookup
Default Server:  dns.domainname.com
Address:  192.168.1.16

> set querytype=any
> domainname.com
Server:  dns.domainname.com
Address:  192.168.1.16

domainname.com     nameserver = dns.domainname.com
domainname.com
        origin = dns.domainname.com
        mail addr = (root)
        serial = 97
        refresh = 3600 (1H)
        retry   = 600 (10M)
        expire  = 86400 (1D)
        minimum ttl = 3600 (1H)
domainname.com     record type 65281, interpreted as:
?.                      0S IN 65281     \#(     ; unknown RR type
00 00 00 00 00 00 00 01 00 00 02 58 00 00 00 02 ; ...........X....
c0 a8 01 10 c0 a8 01 05 )                       ; ........
dns.domainname.com     internet address = 192.168.1.16

-------------------------------------------------------------
(some whitespace from above was removed to make it lookpretty)

the interesting bit, I think, is the 'unknown RR type' and 'record type 
65281' parts.   more research resulted in:

and
http://support.microsoft.com/default.aspx?scid=kb%3ben-us%3b164176

basic summary being that the dns servers are using wins (proprietary 
record in the MS dns stuff) and suggesting that you turn it off.

Would it be a fair statement to say that the wins dns stuff is causing the 
problems?

Thanks for any insights,
David
