How to look at two DNS servers at once?

I have two domains in my work environment, and I'd like to be able to RDP/VNC to clients/servers on both domains. I have both DNS servers listed for primary and secondary on my network connection settings, but it only works for the current primary server.

I have flushed and registered DNS, any ideas how to make them both work at the same time, or at least for specific requests?

Thanks!
 
Both servers should be able to resolve both domains if you want to do this. You could setup conditional forwarding on both.

So if dns1 gets a request ment for domain2 it will forward the request to dns2. And the other way around.

Do the dns servers also resolve internet adresses?
 
Yes they do. Would this require work on the firewall as well? One domain is on our DMZ, and we typically have to add exceptions if we want to use new features like SMTP or anything going between the domains.

Thanks for the help :)
 
Just add an exception in the firewall that allows dns between the 2 servers and you should be good.

However if you've got a DMZ in your network it might be better to do it another way. Point your internal workstation to the dns servers in the internal lan. And just let him forward it to the dns servers in the DMZ if he can't resolve it. Then that server can forward it to your isp's dns server if he can't resolve it.
This way you can block dns traffic going directly outside. And you only have to open up dns traffic between the 2 specific dns server. And of course dns traffic from the dmz dns server and your isp.
