Automating a Backup DHCP Server in Windows Server 2003 and Windows Server 2008

Something that many companies take for granted is their DHCP server. You set one up, and away you go. Even if you really utilize it with reservations, static blocks, extended DNS options, etc... what happens if it crashes? Do you have a backup? Is there an up to date backup with all those reservations and such?

Windows domain computers can still login a few times if your domain controller is unavailable - but they'll still need an IP to get online and perform most of their duties while you deal with why the primary DHCP server is down.

The following discusses creating backups of your Windows Server DHCP server, transferring them to a second server and even automatically enabling the backup if the primary goes down.

Stream multiple computer screens online

The BIG technological hurdle that had to be accomplished for the Headshots from the Heart Marathon was the part that actually turns this into a gaming marathon - we don't want you just watching a webcam feed that shows a bunch of people sitting around playing video games, even with all the extra exciting entertainment and auctions we're going to have going on... we want to bring the action to YOU. We want you to be able to watch us gaming and see every frag we make. In addition to having a webcam that'll show you the hosts and what's going on around us while we play, we're going to be feeding the in-game action DIRECTLY to the stream.

There are a few ways to handle this, and really, it all depends on what exactly you need to setup, and how much money you want to spend.

Just a notice... While I go in-depth in my tutorials, there is a fair amount of stuff here that may be overly technical for some.

Modifying a Borderlands save (to reset the critical kill achievement)

For the Headshots from the Heart Marathon, one of the technical hurdles that we needed to overcome was "What happens if someone hits 2500 kills?"


See, we're taking pledges determined by the number of critical kills we make. Borderlands keeps track of this for us because there's an achievement to reach 2,500 crit-kills. This presents a few problems:

  1. At 2,500 kills, it no longer displays the current count.
  2. Does it keep counting in the background?
    I had a save with well beyond this number, but that was lost last year when a flood blew up my old computer.
  3. Even if it keeps counting and there was a way to access that from the save file, does it max out at some point?
In the following, I'll cover how we plan to deal with this...

Removing a Twitter Virus

During your travels on Internet, it's very possible that you'll come across a website or two that ask to connect to your Twitter profile. Some of these are so you can use your Twitter identity on social platforms, others so that you can manage your Twitter account through another app, website or mobile device.

Not all these platforms are reputable though, so what happens if you suddenly find yourself spamming viagara ads to all your followers?
