can ping DNS servers, still can't resolve hostnames

hello

I'm on a home cable connection using Adelphia, and I have a SonicWall TZ170 wireless firewall. On my laptop (XP) I can connect to the wireless zone (172.16.x.x) and get an IP along with DNS servers (Adelphia). All is well. On my room mates laptop (WIN2K) I can connect to the wireless network,  it gets an IP as well as both Adelphia DNS servers. I can ping both those servers and get a response, but cannot resolve any Internet hostname. When I do an nslookup it can't resolve the Adelphia DNS server and kicks back two timeouts.

I tried manually entering in DNS for the wireless connection on the laptop, same results. I have all filters and security disabled on the firewall. I checked the host file, it has default entries. I flushed the DNS cache as well.

Any ideas?
thanks.

Hi

Your second PC might not be correctly connected to the wireless network, can you ping the default gateway on your network from the second PC. If you can, are you able to ping the DNS servers using thier IP addresses.

Are you using WEP or WPA.

Also try increasing the timeout for NSlookup: from the nslookup command line

set timeout=30

default is 2 seconds

Sorry

Still early in the morning for me, ignore my previous ans, totally misread the question. You still could try the timeout setting and also try a  "set d2" in nslookup.

Have you checked if DNS Client service is running? Or restarting it if it is already running?

have you tried manually setting up your IP and dns servers? Just try the ones that it gives you on your computer that works.
