Exchange cannot deliver mail to servers that do nslookup.
When I try to do a nslookup it fails on finding the domain.
Up til now, i have had the server (Wk3) up front directly connected to the internet with 2 nc inside. One receivning DHCP network address xx.xxx.xxx.20 and the other one as 192.168.3.1. running iis, exchange DC1, DNS, DHCP for lan and internetgateway. Some months ago the servers ARP cache started to mess things up. I think it might have started after installing an update - but I am not sure. After trying to re-install, look for solutions on the internet and so on, I finally decided to put a router between as DHCP and gateway to the internet. I disabled one of the NC on the server and stopped RAS. Now the server is stabile but it will not answer to nslookups from other servers checking for spam. As You can see below, the server is found, but as xxx.local and not the correct xxx.dk. I have tried to put enter a new zone called xxx.dk with the public and the internal ip as hosts creating prt records. The records is created, also the reverse zone for the public domain. Still no answer doing nslookup. Does anyone know how to enter the correct data in DNS and also which services that must be forwarded from the router? And further more do I have to enter another IP (an extra one) on the netcard?
Hope someone can help me.
