SOLUTION FOUND :================

We finally found the solution on an obscure post.

The problem its seems is that there is supposed to be 2 registry keys that relate to dns settings in windows 2000 but for some reason they were missing on our server and thus we got an error saying that the router dns resolver could not initialze.

The solution is really simple. Add a line to your notes.ini

dnsserver=xxxxxxxxxxxxxx,xxxxxxxxxxxxxxx

replacing x with your dns servers and restart your lotus server and all should be well .

USE nslookup to find DNS SERVER .
