same ip being returned for everything in nslookup

[jimmyz]

Something happen in our move from new orleans and back that now our
DNSBL. Blacklist everything through DNS. some reason when your nslookup
it always returns 255.255.255.255 except for internal computers. Any
idea what i need to look at.

nslookup google.com

Address: 10.0.0.2

Name: google.com.Vericore.com
Address: 255.255.255.255

Same with me. Reason is apparently they have a wildcard (an * for an "A"
record) under the zone saying that any queries for anything other than what
records have already been created under the zone, it returns a
255.255.255.255 IP.

first using 'dude':

dude.vericore.com

Server: london.nwtraders.msft
Address: 192.168.5.200

Name: dude.vericore.com
Address: 255.255.255.255

and again using 'bob':

dude.vericore.com

Server: london.nwtraders.msft
Address: 192.168.5.200

Name: dude.vericore.com
Address: 255.255.255.255

and once more using 'vericore':

vericore.vericore.com

Server: london.nwtraders.msft
Address: 192.168.5.200

Name: vericore.vericore.com
Address: 255.255.255.255



YOU will need to change your DNS Search Suffix list to be only vericore.com
instead of vericore.vericore.com, hence what is going on

I changed it to "vericore.com" in the registry on the exchange server.
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters]
"SearchList"="vericore.com"

This fixed my problem thanks for your help! been working on this
problem for a month with 2 different vendors.

In the NIC's IP properties, Advanced, DNS Tab. When you change it, confirm
the change with an ipconfig /all.
