DNS and NDNS issues

First, check the hosts file for curious entries. Also, what does a tracert to an internet ip address show? The original poster should always write the last response !!! Let us know, if the problem is solved !!!

tracert cannot resolve the name, but it will trace and IP address. I can ping the IP but not the name. Hosts and Lmhosts have no unusual entries. Both IE and Firefox have had all proxies disabled. wireshark shows that any attempt to use a DNS is being sent out as a local subnet broadcast (192.168.0.1/24) and is an NBNS query. Thanks for the questions.

So at the command prompt try: arp -d and ipconfig /flushdns Then give tracert another try. Btw: What was the first hop on tracert <ip address>? The original poster should always write the last response !!! Let us know, if the problem is solved !!!

Did the f;ushdns same problem. I can't get the first hop when I use the domain name, tracert needs to resolve the dns before doing the pings. When I use an IP address the first hop is my local gateway 192.168.0.1

So you simply have a DNS problem. What DNS server is shown on: ipconfig /all Best is, you'll post the output of ipconfig /all. The original poster should always write the last response !!! Let us know, if the problem is solved !!!

Not so simple. I'll get the ipconfig /all output later. When I see the packet monitor output, any action that would normally produce a dns request, actually produces a netbios name service request. I will get that output also.

ipconfig /all > ipconfig.txt Open the text file and use copy and past for posting it here. The original poster should always write the last response !!! Let us know, if the problem is solved !!!
