Right now I have seven separate windows 2003 servers at each building that handout DHCP, DNS, Filesharing, Active Directory. Each of these buildings have a T1 connection with cisco routers. In the near future I will have a fiber optic backbone at two building or depending on the cost have this at all seven buildings leased from AT&T. I would like to know if its possible just to have one DHCP server at the main office and have it hand it out over the T1 or fiber optic backbone to each building. each building has 10.23.x.x something for IP Range. Is it possible to have seven different scopes on one server then have the cisco router help at in sending the DHCP renew request back to the server at the office so the computers can get DHCP?
