HI all I have two DNS servers behind my Integrated ISA server that must be pingable(if such a word exists) The DNS is working fine, but i need to add more domains. The Domain Registration server ping the specified DNS servers to check if they exist, but don't succeed. I have turned on IP routing as mentioned in the learning zone, but there is still something missing. I'm only getting time-outs. If you'd like to test, ping dns1.bwi.co.za or dns2.bwi.co.za. Thank you for your intrest Tinus
