So should I leave the domain controller only get result from root hint servers? Is it going to decrease performance? ________________________________ From: isalist-bounce@xxxxxxxxxxxxx [mailto:isalist-bounce@xxxxxxxxxxxxx] On Behalf Of Steve Moffat Sent: Thursday, April 06, 2006 11:33 AM To: ISA Mailing List Subject: [isalist] Re: dns forwarders Do not use forwarders......at all S ________________________________ From: isalist-bounce@xxxxxxxxxxxxx [mailto:isalist-bounce@xxxxxxxxxxxxx] On Behalf Of Ara Avvali Sent: Thursday, April 06, 2006 3:28 PM To: ISA Mailing List Subject: [isalist] dns forwarders 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
