Name resolution problem
I have just installed Windows Vista Ultimate (clean install), and is having
a strange name resolution problem, as shown in the following command sequence: 1. ping amachine.adomain.com Returns "host unknown" 2. ping ip asdress Works. 3. nslookup amachine.adomain.com Returns the correct IP address 4. ipconfig /flushdns Returns ok. 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! Regards; /jb

Name resolution problem
If you do "nslookup" only, do you receive any error? Also check the DNS suffix.

Name resolution problem
NSLOOKUP works fine:
C:\Users\jonny.censurednslookup Standardserver: censured Address: censured:53 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 NSLOOKUP). 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.
