Ok I take your advice. :-)

What about my second question regarding caching?

No, that will increase performance.

 

If your ISP is a busy one and has lots of clients making DNS requests,
then "That" will slow down performance.

So should I leave the domain controller only get result from root hint
servers? Is it going to decrease performance?

Hello everyone.

 

Would someone clear this for me? It's a bit off topic.

 

Domain controller (192.168.0.a) <------> (192.168.0.b) ISA (192.168.1.c)
<----> (192.168.1.d) LinkSys Router <----> ISP

1.      If I want to add forwarders to dns tab of domain controller,
should I put the internal side ip address of router or should I put the
one from ISP? 
2.      Does domain controller cache DNS requests too pretty much like
http caching? Or does it go and ask every single time there is query. 

 

Appreciated
