configure DNS to use DSL connection
Posted on 2006-11-03
I need some DNS advice. I have to maintain a small network with one domain server and 8 workstations but am not well trained in domain management. We have migrated from W2000 server to a new server with Small Business Server 2003. We have no web hosting or Exchange service, only the need to access the web for updates and certain business needs. (My protestations that we don’t really need a domain and its headaches have gone up in smoke as WBS2003 seems to install as a domain by default). The office software needs DNS so I have configured a basic DNS and DHCP service. Our internet access is via DSL using a small Cyberguard router assigned a static lan IP outside the DHCP scope. I tried to duplicate our DNS/DHCP settings but since migrating to the new server we cannot access the Internet and at this point, given all the attendant problems of migrating everything, I am so confused I don’t remember quite how I did it before.
When I override the automatic DNS settings on a workstation and assign the Server as primary and list the router IP as the alternate, the workstation can connect to the Internet. Perhaps I listed the router as a secondary DNS server in the W2000 DNS setup but I can’t seem to add another DNS address in the Scope options of the SBS2003. In these scope options, I do list the router as the gateway and it shows up on the workstations when ipconfig is run but it is obviously not enough. I see a place to add a “forwarding” router but I know I didn’t do that in W2000. My basic question is how to set up internet access in my scenario. I am also curious about the DNS entry in the scope options. I listed the Server as the DNS entry. Is this the correct thing to do or is the fact that the server is designated as a DNS server enough? At any rate, it is here that I thought I could add the router IP but the option to add another entry is grayed out.
I also read somewhere that the forward root zone should be deleted if the server was not connected to the Internet directly. This was done on the W2000 server but there is no root zone on SBS2003 except in the cached forward zone folder but I cannot seem do delete any of this stuff (if necessary). Is any of this relevant in my situation? Am I being acceptably coherent?
