NSLOOKUP works fine:
The domain I am trying to reach is not the same that my machine belongs to.
It is a customer domain, and my local LAN DNS is setup to connect to the
customer's DNS to get the IP addresses for that domain. I don't have a
problem with that, all machines in the net can properly resolve the
addresses belonging to that domain, including the Vista machine (using
The problem seems to be that explorer (and PING) don't seem to use the name
resolution handling as NSLOOKUP uses?
I CAN get the IP address using NSLOOKUP on the address. I CAN'T get the IP
address doing a PING on the same address. In my experience this is
impossible (it is certainly impossible under UNIX), so something must have
been changed in the name resolution functions in Vista.

If you do "nslookup" only, do you receive any error? Also check the DNS

I have just installed Windows Vista Ultimate (clean install), and is having
a strange name resolution problem, as shown in the following command
1. ping amachine.adomain.com
Returns "host unknown"
2. ping <ip asdress>
3. nslookup amachine.adomain.com
Returns the correct IP address
4. ipconfig /flushdns
5. ping amachine.adomain.com
STILL returns "host unknown"
Name resolution works on all the other machines in the LAN (running Windows
2000, XP and 2003).
What is going on? Please advice! Any help is appreciated!
