Linksys router & Win2K Domain Controller

The short answer to your question is yes you can, but NOT as you are currently configured.

Issues:

DNS: Your server hopefully has a static IP address. Otherwise AD will not operate properly. You also need to have a local DNS server in orderfor AD to work properly. AD requires a DNS server that is capable of dynamic updates. This is because AD creates many extra entries in DNS as part of AD configuration. MOST ISP DNS servers either don't have, or won't allow this capability. You mayhave AD installed, but it is not working properly (try setting up another DC - I guarentee it won't work). Install and configure DNS locally! Your DNS server needs to point to itself for DNS. You need to add your ISP's DNS server in the Forwarders section of DNS configuration. All clients need to point to your local DNS server (either hard-coded or through DHCP - see below).

DHCP: If your clients are receiving DHCP leases from your router instead of an internal DHCP server, they are receiving DNS information relating to your ISP instead of DNS information that relates to your domain. You need to install, configure, and authorize DHCP on your DC and turn off the DHCP capability on the router.

WINS: If any of your clients are running any operating system prior to Win2K, you really need to have WINS installed and running in order for your clients to be be able to browse the network consistantly.

Let me know if you need clarification on anything.

As Tim said yes you can, but not as you are configured.

Time has outlined everthing that the server needs to be configured as. I run a test W2K PDC server test bed running AD, Exchange 2000, SQL, ISA server with a couple of clients and a seperate computer off the domain [use it as a remote access computer] all behind a Linksys router. Works just great. Configure your system as Tim pointed out disabling DHCP from the router and setup a static scheme. Let the PDC with DHCP running service domain clients via a switch. The PDC can act a proxy for the clients internet access.

Active Directory needs DNS running. Have your Win 2k Domain server run the DNS service but have it foward to the DNS address of your ISP for public names. Do not use the Linksys as your DHCP server as in Win2k Domain, all DHCP servers must be authorized. Instead have the same win 2k server be the DHCP, and DNS server for your domain. These services actually consume very little resources. See your Linksys documentation on how to turn off the DHCP server. Also see Win2k help on how to creat a DNS server and have it forard. You can give your network the following type of name somecompany.local Notice the domain qualifier local as opposed to com, net org etc. Hope I helped

you need DNS with windows 2000 AD. as long as all systems are in the same subnet you should be cool
