Configure Windows Server 2008 router

Experimental environment: a Windows Server 2008 server, configure two network cards, one card belonging to A network (192.168.1.0/24),IP address: 192.168.1.254/24, a network card belonging to B network (192.168.2.0/24) , IP address: 192.168.2.254/24. And change the card name:

A network a Windows XP client, IP address: 192.168.1.1/24, Gateway: 192.168.1.254.
B network a Windows 7 client, IP address: 192.168.2.1/24, Gateway: 192.168.2.254.
Client communications if the Windows Server 2008 server is configured router, and use the ping command to test network client A and B can network. First three computers Windows firewall turned off, because it will block the ping command sends data packets. Since we do not have the routing capabilities of Windows Server 2008 server enabled, so both the client is still unable to communicate.
