Don't like the snow? You can make a bookmark with the following text instead of a url: javascript:snowStorm.toggleSnow(). Clicking it will toggle the snow on and off.
Our new Indie Games subforum is now open for business in G&T. Go and check it out, you might land a code for a free game. If you're developing an indie game and want to post about it, follow these directions. If you don't, he'll break your legs! Hahaha! Seriously though.
Our rules have been updated and given their own forum. Go and look at them! They are nice, and there may be new ones that you didn't know about! Hooray for rules! Hooray for The System! Hooray for Conforming!

LAN Troubleshooting

Does anyone know of any good utilities to help diagnose LAN problems? I have a 30 or so system LAN (with a couple of servers) that functions fine most of the time. Recently, we have had several systems that will intermittently drop off the network. It does not appear tied to any specific system or hardware. (I did once notice that one of our switches was having collisions. A reboot of that switch fixed it). I am seeing nothing unusual on our domain controller to indicate any dhcp, dns, or wins issues. Is there any type of monitoring software anyone is familiar with that could help me track down the problem?

    Switches don't have collisions. If you're network device has a collision indicator, that is a Hub, and you should replace it with a switch.

    Pretty much every utility you need to diagnose network issues is built into Windows and is accessable via the command line:

    ipconfig
    ping
    tracert
    netstat
    nbtstat

    Other than that, the event viewer logs on your DNS/DHCP/WINS server should provide you with any other information you need.

    In addition, if you need more industrial strength tools, there are liveCDs and VMs designed for network administration, that come with tools like Snort.
