I've created a workgroup separated from our domain for security reasons. The workstations within the workgroup use 1 server that contains the database, I want that server to act as proxy server and dhcp server at the same time. The server has 2 NICS one connected to the rest of the workstations within the workgroup and the other one to our domain, so in effect the server is not using any public IP and it is the only connection to our domain. Is this setup possible in ISA? If yes, how will I going to configure it? In effect I'll be using a proxy server within a proxy server. The server uses win2k and SP4. Also, allow me to ask you if dhcp server can be used in the said setup? I'm having problem configuring the DHCP server. I couldn't able to start the DHCP server service. Thank you and more power!
