Very strage problem... I can ping anything on our local network by IP address, but not by name.  Interestingly,  I can ping by name foreign websites (such as google.com) without a problem.  Web browsing works fine.  Other computers on our network have exactly the same DNS settings and can ping a local computer just fine.  ipconfig /all on my computer shows the same settings (aside from my IP address) as other computers which work fine.  Because of this inability to resolve names, I can't login to my domain and my login scripts don't get executed.

I have never seen a problem like this before.  Normally, it's a simple DNS issue, but my DNS entries are correct. I can ping our domain controller at 192.168.1.10 but not by name even though IT is a DNS server and its address is in my DNS list.

All my firewalls are off, and no anti-virus is loaded.  The DNS client service is running.

This all started happening after installing IE7, visio pro 2003, and getting the latest XP updates--which were only a few since I update regularly  I have tried rolling back to IE6 and undoing all updates to no avail.

try talking to your local dns server by opening up the command line and typing 'nslookup'. This will connect you to your primary dns server, now type in the name of your local server that is not resolving. What error do you get if any?

Is the Primary DNS Suffix on your PC correctly set?

If you try and ping an internal machine by it's FQDN does it work?

Well, I must correct myself.  My ipconfig /all settings were not the same.  I just noticed my node type was set to "Peer-Peer".  I have no idea how this happened.  I did not join any p-2-p networks recently, and everything was working fine yesterday.

I ran regedit, and went to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\NetBT\Parameters then deleted the DhcpNodeType key and rebooted.

All working fine now.  Perhaps nstand's advice would have led me to the same answer, but I'm not about to go back to peer-peer mode to find out!

Sorry for the mis-info.

Thanks for the tip Chris!  I wish I could split my points between you two.  I have unlimited points so I could care less, but don't want to mislead any users looking for solutions.

Take care guys.
