I have a win nT server and win 2000 prof nodes on a network. I have a set of fixed static IPS for T1 connectoin with me for my lab in the school. I have CISCO catalyst 2900 series switch in the lab. Currently I have set the IPS manually an all th machines and have made a domain in the server to which the clients logon successfully.
Now I want to use DHCP on the NT box to distribure the fixed IPs. I actually managed that. But people outside my lab(from other departments) are also able to take my set of DHCP IPs. So I turned DHCP off. How can I use DHCP and still avoid the outsiders to take IPs from my server. Is there a way in which I can allow a certain set of computers (based on comp name) to take IPs from the server?
I tried doing "reservations" but I read somewhere that they wont forcefully take the IP if its taken by someone else (this case - an outsider). If its not true then do I have to take the MAC addresses of all the machines and put them in "unique identifier" field while making reservations?? Can I do something to the CISCO switch to stop broadcasting??
