# 4.2. Configuring Windows NT

1. If you haven't installed your network card and adapter driver, do so now. Descriptions to perform this task is beyond the scope of this document.

2. Go to 'Control Panel' --> 'Network' --> Protocols

3. Add the TCP/IP Protocol and related Components from the 'Add Software' menu if you don't have TCP/IP service installed already.

4. Under 'Network Software and Adapter Cards' section, highlight the 'TCP/IP Protocol' in the 'Installed Network Software' selection box.

5. In 'TCP/IP Configuration', select the appropriate adapter, e.g. `[1]Intel EtherExpress Pro/100+`. Then set the IP Address to 192.168.0.x (1 < x < 255), then set the Subnet Mask to 255.255.255.0 and Default Gateway to 192.168.0.1.

6. Do not enable any of the following options (unless you know what you are doing):

   - 'Automatic DHCP Configuration' : Unless you have a DHCP server running on your network.

   - Put anything in the 'WINS Server' input areas : Unless you have setup one or more WINS servers.

   - Enable IP Forwardings : Unless you are routing on your NT machine and really -REALLY- know EXACTLY what you're doing.

7. Click 'DNS', fill in the appropriate information that your Linux host uses (usually found in /etc/resolv.conf) and then click 'OK' when you're done.

8. Click 'Advanced', be sure to DISABLE 'DNS for Windows Name Resolution' and 'Enable LMHOSTS lookup' unless you known what these options do. If you want to use a LMHOSTS file, it is stored in C:\winnt\system32\drivers\etc.

9. Click 'OK' on all dialog boxes and restart the system.

10. `As an initial test, ping` the Linux MASQ server to test the network connection: 'File/Run', type: `ping 192.168.0.1`(This is only an INTERNAL LAN connection test, you you might not be able to `ping` the outside world yet.) If you don't see any "replies" to your PINGs, please verify your network configuration.
