How to Stop - Internet Connection Sharing

I have installed DNS on a small workgroup applicaton
server with two NICs. The server is
named "ourorganization.local" and was suppose to have
isolate the Intranet from the Internet.

The Primary NIC IP is 10.10.0.2 and is the DHCP server
for the local Intranet. The Secondary NIC IP is
192.168.1.253, Gateway of 192.168.1.1.

The primary NIC is used to access the server for daily
tasks, the secondary NIC is used for remote access into
PC using RADMIN software for PC management.

I incorrectly turned on DNS forward lookup for the
10.10.0.2 address. (Is this what has caused the Internet
Connection Sharing between the two NICs?)

How do I break the connection between the two NICs
isolating the 10.10.0.x Intranet from the Internet?

Interaction between subnets depends on IP routing. And Internet
connection sharing requires ICS or NAT. Making changes to DNS would not
affect that.

If RRAS is enabled, check the RRAS console to see what is set up. If
RRAS is not configured, check that IP routing is disabled.

HKLM\SYSTEM\CurrentControlSet\Services\Tcpip\Param eters
Set the following registry value:


Value Name: IPEnableRouter
Value type: REG_DWORD

1 = enabled, 0=disabled.
