Super DNS headaches...

[MrDoom]

Greetings!

 

I've got a bit of a strange one, its either related to my router or Server essentials 2012, but i can't find anything wrong on the router yet, so I thought i'd try here. I recently swapped out a basic linksys router for a Cisco RV042G, as part of a future plan to link to sites together. I copied over all firewall and static IP assignments, and bingo! everything is peachy. Except, they can't resolve their own website. Of course, i assume this has to do with the router, since it wasn't an issue before, but i can't see anything wrong. So, i'm assuming i might have done something wrong on the DNS module of SE2012, that was somehow a non-issue until i switched to a "pro-sumer" router. They can visit any website, but their own.

 

other possible relevant info:

 

Website url is www.businessname.com

local domain is businessname.local

 

server has its own IP, as well as 2 ISP and 1 Google DNS entered into the NIC settings, but just 2 ISP and 1 google DNS entered as a forwarders.

computers connected to the network, use the Server's IP, and one ISP DNS address.

 

this is driving me crazy and i think i don't quite know enough, and instead have just made myself dangerous, instead of useful.

 

Thanks in advance,

 

Doomed.

Clearly your problem is locally created and down to your own incorrect DNS config.

 

If your .local server is also a local DNS the only DNS setting should be itself or 127.0.0.1

External DNS entries must be set in the forwarders section of the a Windows DNS service.

 

Do some more homework and google Windows a Split DNS

Better still start again and use your FQDN on the local LAN and create the correct Forward Zone entries for your FQDN external hosts.

 

KISS.. mistakes at this stage will haunt you forever, get your DNS right from the outset.

DNS on a DC should always (very few exceptions) be pointing to itself (or another DC on that domain).

Thanks. Reading up on Split DNS now. I couldn't agree more about kiss and about mistakes haunting me forever.
