+ 0 Votes RE: DNS setup advice Matthew S 5 years ago Someone with more relevant experience may provide better detail.My take based on past experience would be keep it simple, which means using Win2003 server to the max, and leave your routers to route:- Run DHCP on Win2003 Server (optional but cleaner, and enables dynamic mapping of AD objects, DNS entries (for clients) & IP addresses)- If you leave the Linksys DHCP running, you need to override the DNS server settings in the DHCP settings to point to your Win2003 Server (i.e. DNS set to 192.168.1.2) not your ISP's DNS services.- Set up DNS forwarding on Win2003 to your ISP's DNS servers or utlize a service such as OpenDNS (which I use and beleive is provides superior performance & results). Running DNS on Win2003 server will improve general DNS look-up performance because it will cache DNS look-ups, saving the latency of going out to your ISP's servers every time.Hope this helps. + 0 Votes DNS Setup Advice erickson147 5 years ago Thanks for the fast response Matthew. I'm going to be working on this configuration later this afternoon. I'm going to try using your suggestion of setting up DHCP on the Win2003 server, and creating a forward to the ISPs DNS. This should also help me with my faster logon response?If I leave my Linksys DHCP running and point to Win2003 server 192.168.1.2. I would still need to setup forwarding on the Win2003 server to the ISPs DNS? Correct?Since my Win2003 server is my DC and running AD would I be able to run a program such as OpenDNS? + 0 Votes DNS setup Dean Wheatley 5 years ago Just to add to Matthews post, OpenDNS is a web based service which you create a user account on and is extremely good imo. My suggestion would be to setup your DNS domain on your DC, along with DHCP. (Make sure you set you DNS to only use secure updates.) On your DHCP scope set your server IP address as the gateway, and DNS server, that way each client will have the same gateway and DNS settings.Using routing and remote access tell your server the address of the router as it's gateway. Then set your routers DNS to the openDNS or your ISP's DNS server.That should create a more secure and uniform environment. There may be better ways to do it but this ways has worked well for my network for over a year without issue.Hope this helpsDean + 0 Votes Setup DNS from scratch erickson147 5 years ago HELP!

Since your linksys router is running DHCP, you need to create options in DHCP for the default gateway [linksys router]. I believe the option # is 3. With that, clients now have the information for the default gateway. With DNS, queries not resolved by your DNS server should be forwarded to root hint servers on the internet. + 0 Votes DC/DNS server erickson147 5 years ago Currently my clients get DCHP from the Linksys router. So you are saying to add the servers IP to the linksys routers DNS entry?Forward zone: NTI_Domain (Domain Name)What settings do I need for this? I made a primary.Reverse Zone: not configuredForward: 216.x.x.x (ISP DNS) 216.x.x.x (ISP DNS)Root: was never configuredCan I delete these DNS entries and start from scratch?

The board is an Intel DP35DP desktop board and I read that the board doesn't support Windows server 2003 drivers? Sorry to all, but I walked into all of this mess.Thanks for all the help, it is much needed. + 0 Votes Don't think the board is the problem... CG IT 5 years ago here's the deal. workstations on the network must use the W2003 Active Directory domain controller which also has DNS service running on it as their preferred DNS server in TCP/IP settings of their network card. This is for Active Directory login purposes. This is most likely why it takes users a long time to log in. They don't have the correct DNS server listed to find your W2003 domain controller. The problem arises as to how are workstations going to get the information they need to find the AD Domain Controller? [and get to the internet[Since your router is providing DHCP services, you have to create options in DHCP to provide workstations with DNS information. I believe option 6 is for DNS servers. Another problem is configuring the default gateway. Again, you create an option in DHCP specifying the routers address as the default gateway . Now, I'm not sure if your consumer level Linksys router is capable of having DHCP options. If not, you'll have to resort to turning that off, using your Cisco router for DHCP which I know can have options, or using your W2003 Server as your DHCP server and going that route. + 0 Votes clients must use your DC/DNS server CG IT 5 years ago in their DNS TCP/IP settings.What extension did you use for a domain name eg. .com/.net or a non routable .local? your linksys router is probably the real culprit since you are using 2 routers thus have 2 networks.
