Hi! I just want to seek advise if it is good to install the ISA server 2006 on a domain controller with dhcp,active directory and dns installed. Actually I have installed it and after installing it I found out that the the client in my network can no longer connect to my domain controller and cannot get an ip address to my domain server (Windows Server 2003). How can I solve this problem. I am using Vista business for client computers. I do this setup because we have limited budget and no intention of buying a computer for ISA server. Can someone give me advise.
