New router - DNS problem!

By dagppm ·
I have recently switched from using a straightforward hub to a router/gateway. I have installed a domain controller w2k03 on the same 192.168.x.x subnet as the router no problem. It is configured with its own IP address as preferred DNS server, and connects to the gateway and Internet with no further configuration

The problem i have is joining other computers to the domain. I am not sure what addresses they should be configured with. I point them at my domain controller but they receive error "domain controller could not be contacted". They are configured with the default gateway of the router and i realise that the router has no idea of my dc's ip address, but dont know how to resolve. Does any body else please?

Your router isn't configured with the subnets you have created?

Can the clients pass traffic from there subnet out to the Internet?

You router should be able to see all of the subnets behind it. Otherwise, it would never work.

The other PC's are on the same 192.168.x.x subnet as the DC??

How can the other PC's connect to the DC - how are they all physically connected - via a Hub/Switch, or are all the PC's connected to the router as well.

Can you ping the DC from a PC.
Can you ping the router from a PC.

Have you created the computer account/s in the DC.
Have you created user account/s in the DC.

Hello there and thanks for advice. haven't worked out where to post reply on discussion board so sending pm.

Managed to get my domain environment working. All pcs were connected to adsl router and could ping each other, all on 192.168.1.x subnet

problem was that no adirectory records were being created on DC, can only assume that some DNS configuration was being passed to dc from router and affecting dcpromo

connected dc to simple hub, ran dcpromo successfully so as to create ad records, stub zones.

configured dc with gateway of the router, and pointed pcs to the dc for DNS and the router as gateway. Also configured DNS to forward all non-domain requests to router.

All the best
