I am having dificulty reaching Tahoo.com from my office network. I have
verified DNS is resolving and I can get to ANY other web site. I have my
W2003 DNS server set up with my ISPs DNS as a forwarder. I cannot even get
there by typing the IP into the browser. If I pu my ISPs DNS in my
workstations DNS setting I have no problems. Any Ideas
 
from a command line

dnscmd /Info /EnableEDNSProbes 0

If you don't have dnscmd (and are not afraid of the registry), you can go
directly to the registry and create this key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\DNS\Parameters
EnableEDNSProbes (DWORD)
set the value to 0

Restart DNS service

Absolutely the fix. I actually found the resolution in a Microsoft KB
article. The problem is not so much in the EDNS on the server as it is in
the PIX firewall. The PIX prevents large UDP request and the best fix is to
alter the PIX but your way is actually the fastest ( i know you know this but
for anyone else for this problem i will state it any way). Thank you for
your help.

I did this because our PIX won't pass the large UDP packets, and it worked.

Now I can't resolve ftp.nai.com

Could the 2 be related?? When I do a simple nslookup on ftp.nai.com, I get:
ftp.nai.com
Click to expand...
Server: dogwood.longwood.edu
Address: 159.230.4.130

*** dogwood.longwood.edu can't find ftp.nai.com: Server failed


When I try other DNS servers, I get something unusual:
ftp.nai.com
Click to expand...
Server: dns1.nai.com
Address: 205.227.136.210

Name: ftp.nai.com
Served by:
- dal3dns.nai.com
205.227.136.200
ftp.nai.com
- snc3dns.nai.com
67.97.80.200
ftp.nai.com


I have never seen this kind of return - any ideas?
 
In my cached zone, there is an FTP zone beneath the NAI zone.

The FTP zone has no A records, just 2 NS records. Anybody seen this
behavior??

Blake,

I have not seen this particular problem but I have seen similar incorrect
entries in the cache. I would try clearing the cache on all DNS servers and
restarting the service.
 
I have tried clearing the cache, to no avail

This is not your "personal problem". There is nothing for YOU to fix at your
end.

to confirm this, try:
nslookup
server dns1.nai.com
set q=a
ftp.nai.com

you will see that you only get nameserver entries. This is nai's problem,
not yours.
