I have a server with two NICs. NIC 1 is connected to the modem with the following configuration IP: 192.168.1.2 (static) Subnet Mask: 255.255.255.0 Gateway: 192.168.1.1 (IP of the modem) Primary dns: 80.87.78.11 Alternate dns: 80.87.78.4 NIC 2 is connected to the switch, with the switch connected to the client computers. NIC 2 is with the following configuration: IP: 192.168.0.1 (static) Subnet Mask: 255.255.255.0 Gateway: 192.168.1.1 (Ip address of the modem) Primary dns: 192.168.0.1 After that I installed Active directory, DNS and DHCP with an IP range of 192.168.0.4 - 192.168.0.120. I also checked the share network option on the NIC 1. Even though the server leases the IP to the client computers alright, the client computers cannot browse the internet even though the server can browse. What have I not down right. I need help. Thanks

You should not run your DC connected to two networks. SBS will run like this but standard Windows server will give you all sorts of odd problems with name resolution and browsing. Either use two servers (one router and one domain controller) or use a hardware router so that the DC has only one (private) IP. You will also need to modify your DNS if you run AD. AD is not compatible with the dns relay method used by NAT devices. Bill

Hi, Thanks for posting here. I agree with bill that you should not deploy active directory service on a multihomed server. Meanwhile, you may follow the introduction in the link below to configure your server to implement internet connection : Internet Connection Sharing and network address translat http://technet.microsoft.com/en-us/library/cc758507(WS.10).aspx Thanks.
