Hi everyone, I am trying to setup a domain-based home server. My situation is as follow: 1. Windows Server 2003 machine (with 2 network adapter) 2. Windows 7 machine (1 network adapter) On the server machine, 1 network port is connected to Internet (directly) (named eth0), another one is connected to the 7 machine (named eth1). I have add Domain Controller/DNS/DHCP/Remote access/Application- roles to my server. As for the eth0 adapter, I only changed DNS server to 127.0.0.1 and leave IP to automatic assigned by my ISP. As for the eth1 adapter, I manually config IP 192.168.0.1 (255.255.255.0), DNS server is set to 192.168.0.1 I have configed the server's DNS Server to forward DNS queries. (using the ISP's DNS as forwarder). I chose the Internet IP of eth0 and the server's local IP (192.168.0.1) as Interface IP. At first, it was working and the client computer can connect to internet and file sharing ... However today it just suddenly stopped working. The client's browser kept sending requests but no reply ... And as I tried to ping, only the client can ping the server but the server cannot ping the client (eventhough it can resolve the IP of the client)... Can anyone help me on this !!! Is this a correct configuration? Does it have anything to do with gateway's IP (since I left it empty)?
