Consequently the Network Unreachable message could be the result of a misconfigured mask value in the router. That was the only difference I saw on the networking side between 2k3 and 2k8: how they answered differently with *nix traceroutes.

It's not based on pingability. Configure both same as the configurations you have on the working wifi interface. Summary: Port Unreachable The host and the communications infrastructure are working properly. That's a good question, but I don't really think so, just thinking on what the traceroute is doing, since it's really not using any *nix or posix service.

The nice thing about a Port Unreachable message is that it confirms proper operation of the intervening communications infrastructure and the presence of the destination host processor. https://social.technet.microsoft.com/Forums/windowsserver/en-US/ab0614f9-1c39-4646-aa8a-b1eb1257baa3/weird-dns-udp-time-out-issue-with-windows-2008-r2?forum=winserverNIS The console has been configured with a list of IP addresses to poll for the acquisition of network management data. This could be the result of a router in the communications path that discarded the frame or, perhaps, the ultimate destination host computer did not have the resources to process the The protocol handler then reports Destination Unreachable - Port Unreachable.

I know this is a very old post, but I just ran into this problem and solved it. When troubleshooting a Port Unreachable error it is necessary to know what is supposed to be at the indicated (unreachable) port. When the DNS Server service receives a response that has two kinds of records, it ignores the CNAME record. Many thanks, Sir PClick to expand...

The point of failure identifies itself by sending the ICMP Destination Unreachable message. Frank...

The actual 0x0000007e error messages are formatted usually gives detailed error 904 port unreachable dns information. This is the Destination Unreachable message.
