I see a couple of items:
Server NIC to clients:
IP Address 192.168.201.2
Subnet Mask 255.255.255.192 <- you have address space for 63 clients
Default Gateway <- Set this default gateway to the other NIC provided you have routing enabled on this server.
DHCP Server 192.168.201.2 <- not needed on this NIC as it should be a static address; unless you have a reservation in DHCP
Primary Wins Server 220.127.116.11 <- this is not the WINS server for your network, it should be this server providing WINS services if needed
Secondary Wins Server 18.104.22.168 <- see note above
Enabling IP Routing
By default, IP routing is disabled. To enable IP routing, you must allow the computer to
forward IP packets it receives. This requires a change to the Windows 2000 system registry.
When you enable the Routing and Remote Access service for IP routing,
this registry entry is made automatically.
To enable IP routing
1. From the Start menu, click Run.
2. Type regedt32.exe or regedit.exe, and then click OK.
3.In a registry editor, navigate to
HKEY_LOCAL_MACHINE \SYSTEM\CurrentControlSet\Services\Tcpip \Parameters
4. Select the “IPEnableRouter” entry (by defining as value : 1 )
5. To enable IP routing for all network connections installed and used by this computer, assign a value of 1.
To do this in regedit.exe, right-click the entry, and then click Modify.
In regedt32.exe, click on the wanted entry, click on Edit, and then click on the appropriate menu choice.
6.Close the registry editor.
It is required to reboot Windows 2000 for this change to take effect.
Another method is:
Open “Routing and Remote Access” on the server. In the console tree, right-click the server you want to enable, and then click Configure and Enable Routing and Remote Access. Follow the instructions in the Routing and Remote Access wizard.
