It will go to the second entry ONLY if a query to the first entry returns a NULL (doesn't) respond.If the first entry returns an NXDOMAIN (record doesn't exist), it will I disabled all the profiles (Domain, Public and Private), the symptoms are still there. The indicated port process was either not running or was swapped out. Is the port in the router configured with the correct address mask value?

Basically it's a workaround to help DNS. Traceroute seems to be the only program affected right now and there was no point dedicating resource to resolve this issue, at least for our entreprise point of view. Replies: 4 Views: 3,074 Thread Status: Not open for further replies. Furthermore, the intended destination host was on-line and willing to accept the frame into its communications buffer.
Not the answer you're looking for? additional hints It's provided some insight but I am not that familiar with low-level TCP/IP stuff so I don't know what to make of it all. Domain Auctions .CO Auction: Paramour.co + Others. Good idea though!

So the question is, what do I need to do? Years ago prior to EDNS0 support, ifthe UDP response is greated than 512 bytes, it would revert to TCP to get the whole answer.

Since the DNS issue was fixed and the cause was found, we did not investigate further into the problem since I did not noticed any other problem on the networking side.
It's not based on pingability.

After activating ipv6 additional processing, the 106 error also was gone and anything is working fine now.
This was noticed right after the migration from Win2k3 to Wind2k8. Yeah, I know that linking DNS performance with traceroute was a stretch... If you configure it right the hosting provider's DNS should answer queries independently of whether it's already the "primary" nameserver (pointed by 123-reg) or not. This could cause a delay as well until it switches to the secondary IP on the DNS server list.

Remember, a Port Unreachable message says that the process that is using a Port in the Layer 4 protocol is missing, but the protocol itself is working. The idea is to check for anomalies or errors reported directly by the hosting provider.
By default nslookup, justt like the client side resolver service, uses UDP. If, however, the router ARP's and receives no answer then it sends a Destination Unreachable - Host Unreachable message back to the originator.
