LAN tweak guide
Last Updated on December 02, 1999 by Thomas McGuire

I had originally intended to make this an addition to the Modem guide, however given the size of it I decided otherwise. As a result some of the information may be repeated in the Modem guide.

Setting it up

Go to Threshís Firingsquad, it has 2 guides up, How to setup a LAN, & A guide to Windows Networking. I suggest you read them both for information on how to setup a LAN & get it running. I will cover how to get them running better.

Network cards

Begin by downloading & installing the latest driver/update for your card from the manufacturer. This may fix any problem/compatibility issues with the card & generally give better performance.

Open up Network properties in the Control panel, selecting the appropriate adapter. Then go into the adapters Properties.

Select the Driver type tab, selecting Enhanced mode (32bit and 16bit) NDIS driver.

Under the Bindings tab, select only TCP/IP. Select others only if required to do so, this will give you the optimal speed.

Under the Advanced tab select the best choice that the LAN is capable of, e.g. if you (& the LAN) can support Full-duplex operation, then choose so accordingly.


Start by removing any unnecessary Protocols, Adapters, Clients & Services from the Network control panel.

Now, select TCP/IP & hit Properties. For the sake of these guide the LAN will be a static one, i.e. static IP addresses & such rather than dynamically assigned. Iíll go into details for a dynamic one at a later date.

Under the DNS Configuration tab select Enable DNS. Once more, fill in the required host addresses as applicable.

If you have IPX/SPX-compatible protocol installed, then set it up as follows.

If the PC is connected to the Internet & uses Dial-up adapter set it as follows.

Finally, for Use IPX header compression choose No. If you use the PC for browsing & downloading mainly, then set it to Yes instead. Click Ok once all those changes have been made.

If the PC is connected to the Internet & uses Dial-up adapter set it as follows.

Also, set up your network devices MTU,TTL, etc. as described in the Windows registry guide. If you are using the IPX/SPX protocol you can also set the NDI-cache size.

Most LANís connected to the Internet have permanent connections & in Internet options, under the Connections tab, select Never dial a connection. This may help others who are also connect to the Internet via DSL or other such connection, where no dial-up is necessary to connect.

File & printer sharing

Again, up the Network control panel, clicking on the File & Printer sharing button. Enable or disable them as required. For performance & more importantly security reasons it would be best to disable them, particularly if the machine is connected to the Internet.

NOTE - If you have chosen to enable it you must also put a tick in the, I want to enable NetBIOS over TCP/IP option in the other Network protocols.


This guide should help you in optimizing your LAN for better data transfers & such, & of course making LAN games more enjoyable. Feel free to make any suggestions about this guide. Some of this is in testing & may need to be updated for better results. Let me know if it helps.
