RAS & Gateways

I have two Domain Controllers. DC1 and DC2. DC1 is the Primary DHCP & DNS. DC2 is the 2ndary DNS and acts as the RAS.

Ive emplemented the RAS basically to connect the LAN to the internet.

Problem: The only way any PC (except for the RAS Server) can get online is to manually impute the IP address/Gateways in the TCP/IP settings.

Noticed: WHen I ipconfig /renew the default gateway is allways blank.

Questions: SHouldnt the DHCP server send this info to all the clients? Am I overlooking something?
