fusi0n Posted January 7, 2015 Share Posted January 7, 2015 Right now, we are having major issues with our DNS servers being down in the main office. It's due to a fiber cut.. The DNS servers on the local DNS server that is connected to the domain (although, won't reach out to anyone because of the main VPN tunnel is down), right now, the forwarder DNS servers are two DNS servers in the other office. Can I add 8.8.8.8 as a fowarder? Thanks! Link to comment Share on other sites More sharing options...
fusi0n Posted January 7, 2015 Author Share Posted January 7, 2015 I think it's working fine.. I just need to make this DNS server a forwarder in the long run so this doesn't happen again Link to comment Share on other sites More sharing options...
DeadEndAccount Posted January 7, 2015 Share Posted January 7, 2015 Depending where you are it might end up causing problems when it comes to caching services which use the DNS that you're using to decide what is the closet server to serve content from - particularly important if you're in New Zealand and normally the caching will occur in Australia or New Zealand which avoids having to pull data from overseas resulting in a low throughput.

sc302 Veteran Posted January 7, 2015 Veteran Share Posted January 7, 2015 the forwarders should always point to external dns servers....there is no reason to point to other dns servers as your AD dns servers replicate to each other, unless there is another domain on the network...then the questions becomes why do you have two domains on the same network, not really common place fusi0n 1 Share Link to comment Share on other sites More sharing options...

When replication fails the netlogon share and the sysvol share no longer function/are no longer shared. Thanks.. I don't have two domains on the same network. Sorry. I must of not said it correctly. The previous vendor set this up,and I'm still going through all of it fixing a lot of mistakes. The local site DNS server was forwarding to another DNS that is on our domain. The issue is there is no connection to that DNS server because of the massive AT&T outage. I have put in the external forwarders and everything has started working again, internet wise.
