You mean the "multiple A" record pb?  yes, several DLers have reported back 
to me on this.

>could you please tell me which "buggy" zones you found?

3 or 4 people had serious pb with a BIND8/NT doing an A query for 
adsdl.conducent.com, but there DNS was a lot more screwed a couple of 
months ago, and they have cleaned it up quite a bit.  The last time I 
helped a n ISP get around the pb, about 2 weeks ago, adsdl.conducent.com 
was returning about 60 A records, and we fixed him with a combo of my 
bka.bat and dummy conducent zone tactics. He runs just fine now.

Then last week, a guy contacted me about running 8.2.2 p5 on W2K.  I said 
it wasn't a tested platform (although there have been reports of BIND 8.2.2 
p5 for NT4 working fine on W2K).  It worked fine for him, so I asked him 
if, while he stood buy, could I try to hang his BIND with the 
adsdl.conducent.com query. I tried many times, but conducent.com's 
delegation was so screwed up that I couldn't get their "SCA" ns's to answer 
the A query, and it's only the SCA NS's that have the 60 A  records, the 
other 3 NS's only return 2 records, and BIND won't hang with just 1 or 2 A 
records.   So I couldn't see if 8.2.2 p5's bugs on NT4 port were 
accientally insecticided on W2K.

afaik, there is no list of zones that return dozens of A records.  You'll 
have to develop your own, solving your most frequent pb's with dummy zone, 
and the catching the rest with bka.bat.

If you have this pb, follow the instructions on my bugs.cfm page, combining 
the BKA.bat + dummy zone tactics, and you'll be ok.  Select the dummy zone 
file domain by turning on named logging and then, when named halts, see the 
last one or two queries in the named.run file as candidates for being 
dummied.  Use dig to verify that those zones are returing multiple A records

I still have no esteimated time of arrival for the NT port being fixed BIND 
8.2.3 or of the availability of BIND9 on NT4 or W2K.
