Hope yopu can help with my problem.
I have a server running SBS 2003 R2. I have it configured with a static IP address.
When a client connects we have our server acting as the DHCP server on the network. The DNS server for each client is the IP address of the server, which I understand is how it should be. The problem is that each day BT (our ADSL provider) change the 2 DNS server addresses (I think there can be up to 8 differnet ones).
As the server is acting as the DNS server for the network there have been some 'forwarders' set up to forward DNS requests to the BT DNS servers, however when the 'valid' DNS servers of the day are not at the top of the list we get problems connecting to the internet. We fix this at the moment by moving the two valid DNS servers to the top of the forwarders list.
The question I have is can I set the server up so that it gets the DNS servers automatically from the router. The option to 'Obtain DNS server addresses automatically' is greyed out (I guess it is only enabled if 'Obtain IP address automatically' is enabled).
I realise I can use external DNS servers such as openDNS...but is there a way to get my server to update its forwarders automatically, or should I set the server up in some other way to route DNS requests the the correct DNS servers.
Many thanks for reading this question.
