We have a small non-domain network with 5 XP boxes, 2 Windows 7 boxes, and a pair of linux servers. No DHCP, just static IPs. I added the first Windows 7 machine about 6 months ago and it works fine. I added the second windows 7 machine and it can display the other members of the network - the XP boxes, the other Windows 7 box, and the linux servers. I can ping the other boxes by IP address. The network icon in the system tray shows a caution (yellow triangle with "!"). The self diagnosis says that the DNS server is not responding. I can't ping the gateway - 192.168.1.1 - timed out. I can't ping addresses outside our network. (timed out) I can ping all the other computers in our network by IP address and navigate them, map drives, etc. in windows explorer. The ipconfig is identical to the other windows 7 machine, except the IP address is 192.168.1.115 on the new machine and .126 on the older, working machine. In the NIC setup I have unchecked the IPV6 and etc. leaving only the Client for Microsoft Networks, File and Print sharing for Microsoft, and IPv4 checked. It really is set up identically to the other machine that works - both have static IP addresses, subnet mask of 255.255.255.0, gateway = 192.168.1.1, DNS servers 204.130.255.3 and 209.63.0.6. Any ideas? Your help is appreciated. (why does microsoft insist on stupid interfaces like "home network, work network, or public network" to insulate users from the actual registry settings?!?!? - can we get an option to run in "show me the actual settings mode"?)

1. Response to ping should be allowed 2. What is output from a. ipconfig /all & b. route print ? 3. If analysis does not help, use network monitor to catch network traffic (NM either from Microsoft or Wireshark) 4. Check if there is No alternative NIC settings Rgds Milos

Thanks for the suggestion Michele! Unfortunately it did not make a difference to force 100Mbps. The other Win7 machine didn't need to so I am really stumped here. The self diagnosis says "Windows can't communicate with the device (Primary DNS server)" or something close to that. When I set the DNS server IP address on the local IPConfig to the gateway, it says it can't connect to the DNS server. Baffling.

No one from Microsoft reading these support forums can help?
