Backup (TWO) ISPs/ Backup (TWO) Routers/ Backup (Four) DNS Servers on 2 diffrent networks j.lichtenberger[ at ]gmail.com 4/16/2007 4:12:35 PM Hello All- We have a Windows 2000 domain that is connected to the internet. I have the DNS servers of our ISP listed as forwarders. I'll refer to this as ISP-1 We recently purchased new internet service as a backup in the event of an emergency we can just have someone switch cables and get us back on line. I'll refer to this as ISP-2 My problem is, when I switch us to the ISP-2 connection we can not access the internet unless the DNS servers from ISP-2 are set as forwarders. I want to configure the DNS servers from both ISP as forwarders and leave them set up all the time so that in the event of an emergency we can just switch cables and do not need to modify the DNS settings during the emergency. I tried to do this but I keep getting the following errors in my event log (source: DNS event: 7063). Can these messages be ignored? Is there a better way to set this up? Any help would be greatly appreciated. Thanks, J

Maybe they will allow recursion (to be used as a forwarder) because apparently ISP-1's DNS don't allow that. -- Ace Innovative IT Concepts, Inc (IITCI) Willow Grove, PA This posting is provided "AS-IS" with no warranties or guarantees and confers no rights.
