I have installed a Windows 2000 Server as the domain controller on a LAN running Windows 95 and 98 Workstations. I have set up DHCP for addressing but from time to time the server assigns workstations its own IP address (192.168.0.1), thus of courseconflicts. My scope of addresses is .2 up to .100. How do I eliminate this duplicate IP addressing?

excluded that ip address 192.168.0.1 from the your ip scope. ( better yet, excluded an range of ip address for future use).
or you can reservation the ip for that you domain only.

I still have a problem with 2 particular workstations which I have decided to give static IPs.
What implications/repercussions will this have on performmance?

Go into the DHCP console and expand the Scope in the left panel. Click on "Reservations", then click "Action" tab, then "add new reservation. Here you will be able to add the static address for the server and also the MAC address from the NIC so that there is no misstake. The best proceedure is to create your scope starting after the static addresses. Example: 192.168.0.1 to 192.168.0.10 are asigned adresses for what-ever reason, then start the scope at 192.168.0.20 to leave room for growth. Additional scopes can be added and additional reservations can be added at any time.
