NT 4 Wkstn not using DNS

By nosrednaanit ·
I have an NT Workstation (laptop) that made a trip to Germany for a trade show and when it came back, DNS was no longer working (specifically, I get a "bad IP address" when trying to ping names, and a "server not found or DNS error" message from IE. I've verified via IPCONFIG /all (and the registry) that the correct DNS servers are listed, and this workstation is the only one on our network with this problem. I have put individual listings in a hosts file, and it still gives me a "bad IP address" when trying to ping names (IP addresses work fine). I have used both static and DHCP IP settings. I uninstalled IP, rebooted and then reinstalled IP and re-service packed it (sp6a) - twice. I have even unbound Netbios, just to see what would happen (nothing). My next troubleshooting step was to use Etherpeek to do a packet analysis, and noticed that _no_ DNS packets are being sent from the workstation at all. Not even during start up, pinging, or attempting to access the web. Any ideaof why this workstat

Ask the user what changes were made in Germany (Longshot!)
Check out the TCP/IP properties Tab, has anyone added new rogue WINS or DNS addresses, including Domain names.
Check out the Hosts and LMHosts files for new settings (or missing old settings.)
Try and get a similar laptop, or Workstation, and compare commands, what works, what fails.
Finally does ping ip address, or ping localhost work, if so then its a configuration problem, if not, then its a hardware or reinstall problem.

To tfazer,

Just a little humor, probably the laptop forgot something in Germany. hehehe

First, you may wish to check that the time zone in the laptop had not been changed since it went to a diiferent time zone and back, but only if it had beenchanged.

Secondly, in the DHCP Server, verify that the IP address that you gave to the laptop is in the DHCP's scope, if it has a static address, re-verify that you are using the IP address that correspond to the network.

Third, in the WINS (I assume that your network has one), re-verify that the laptop's computer name is entered correctly (it probably had changed to a German name). (Hey thats only a joke OK, don't get excited), but I still would check it anyway.

Fourth, in the RAS Server, See if the laptop computer name and its correcsponding IP address is still enabled in the RAS Servers clients. If you are using VPN, I suggets that you re-check your protocols.

Fifth, had you tried pinging the laptop IP address from any workstation in the networ
