Setting up Installed Components Continued...

Tweaking out your Internet (TCP/IP) settings however, is a little bit more complicated. There are two routes you can go with this – you can either go for one of the standard IP address ranges (I would recommend the 192.168.0.x range personally) or go for the 125.125.125.x range. I received a lot of ‘flame’ messages over my recommendation of that range in my Win9x LAN tweak guide – so I’m disclaiming now – if you don’t like it, send me some proof as to why. I’ll be honest; I haven’t tested the 125.125.125.x range for speed on Win2k as of yet (even though I’m using it and it runs just fine – just haven’t done a comparison yet). My current theory on the range is that because of the way that the Microsoft programmers choose to code their TCP/IP stacks. Using the recommended range will NOT cause a security issue on your computer as long as you follow my instructions, so don’t worry about your LAN being accessible from the Internet.

TCP/IP Tweaks

Okay, now that I’ve gone into the whole IP address range issue, let's set up your network for optimal performance over TCP/IP. Go into the properties section of the Internet Protocol and put in your chosen IP address (either 192.168.0.x or 125.125.125.x where x is between 1 and 254) and your subnet mask to You probably don’t need to set up a DNS server because you are working with static IP addresses. Then go ahead and click on the advanced button. Assuming you are on a basic network with no special requirements (DHCP, etc), you shouldn’t need any gateways, DNS servers, or WINS addresses. Disable LMHOSTS lookup in the WINS section and disable NetBIOS over TCP/IP. Under Options you are going to want to have IPSEC disabled (under IP Security) and also disable TCP/IP filtering unless you are using a firewall or proxy server (and, unlike what some ‘people’ might think, they are two very different things).

Sharing Folders and File Caching

Sharing folders is done much in the manner that it is done in Win9x. Just go into My Computer, right click on the drive icon and go into its properties. You can set up sharing using the Sharing tab (how…ironic!). There is something of note that you should take a look at though – file caching. It is unlikely that you are going to want or need to have access to your files ‘offline’ (or for that matter, want anyone else to have access to them). There are four possible settings for this – disabled, manual caching for documents, automatic caching for documents, and automatic caching for programs. I recommend setting it to disabled as the other three settings require quite a bit of system overhead on your system and the other systems on your network.
