Internet problem on my LAN

    I have here at work, one lan with several computers with one Win2k Server, with Active Directory and DNS, and with a Linksys WRT54GS with v23 SP1 DD-WRT firmware to wireless and internet access.
    Well, when I turn off the server, to avoid the hanging in the middle of the night (due to some troubles in the OS implementation), the rest of the workstations (with win2k pro) can't access to the internet.

    Does anyone can give me a tip to allow any workstation to access to the internet with the server off ??
    Is there any option on the firmware to allow this?

    the server is handling dhcp and default gateway probably and when the workstations dont have a gateway/ip address they have no internet.

    EDIT: or the dns server goes down... that is probably it.

    yeah, make sure that the workstations are NOT using the win2k server for dhcp and dns. it would be best to provide these services with the linksys.

    The server is not acting like a DHCP server, all my machines are with static ip. The problem is that I have to put on every machine the dns ip, the ip from the server, because of Active Directory. When the server is off, no internet access.
    I suppose that I need to put in the Dns field (on win2k workstations), the ip from the router instead of the ip from the server. But for that, I need that the linksys can manage also the Dns ip from the server (to grant access to the domain). Is this possible??
    Does DD-WRT (or any other firmware) has an option to do what I'm saying, that will allow my machines to have internet with the server off ? And to allow my machines, when the server is on, to log on into the domain and have internet access??
    I think I saw some options that could reseamble what I'm saying but I'm not sure...

    just put the first dns server as the win2k and the secondary as the linksys there are multiple fields for dns ip
