If you are using Server 2008′s built-in “Windows Backup” tool to backup your server, you may run into a problem where the “auto-delete” function does not delete your older VSS copies if your backup destination is not large enough for the disk(s) that you are backing up. Then you will run into failed backups because there is not enough disk space to create the backup copies.
This post should help those struggling to realize the concept of having multiple external IP addresses registered to a single modem.
I’m currently in the process (after a year or so of waiting for my employer’s to get ready for this) of setting something like this up to have two web servers behind one Comcast modem.
We will be hosting an Exchange Server and a Moodle site from two separate servers using just one modem.
You may or may not have the same setup as this guy, but the poster’s give the basics of what you need and how to go about this type of setup.
Have fun!

*Edit*
I have completed my setup at my employer’s location. I replaced their sonicwall as the router and put in an Untangle box as the replacement. That made it easy to setup the additional IP’s as aliases, and create forwarders for the additional Internet IPs > Internal IP’s.
Now, they have two fully functioning websites running on a single cable modem using SNAT or 1:1 NAT. It was quite easy once I had the IP’s actually configured on the modem.
Check out this site if you’re interested in placing some home automation tools, such as light switches, water valves, window / door sensors, or maybe things like home servers or home security cameras.
Most things can be accessed from anywhere in the world, plus the added bonus of sharing certain devices out to friends and family. So, if you’re a photographer (or a wannabe), you can easily share out your photos to friends and family from your own home server.
Water valve busts in your hose while you’re away? The Z-Wave valve can automatically shutoff water to your home, and send you an email and SMS message of what happened, and tell you that it shut off the water to prevent costly repairs (all while you’re not even home!)
Pretty slick stuff!
Think again.

“And you think Apple is taking it seriously too now?
Maiffret: Oh yeah. It’s even a little scarier with them because they try to market themselves as more secure than the PC, that you don’t have to worry about viruses, etc. Anytime there’s been a hacking contest, within a few hours someone’s found a new Apple vulnerability. If they were taking it seriously, they wouldn’t claim to be more secure than Microsoft because they are very much not. And the Apple community is pretty ignorant to the risks that are out there as it relates to Apple. The reason we don’t see more attacks out there compared to Microsoft is because their market share isn’t near what Microsoft’s is.Are they on par as far as code?
Maiffret: I think Microsoft does a better job with their code auditing than folks like Apple do. We’ve only seen a scratching of the surface as far as Apple vulnerabilities because nobody cares to find them. There’s nothing inherent with Apple themselves and their development. The only reason Apple gets little increase in security is because they’re running on top of a Unix-based operating system and they can take advantage of some of the things that have been done for them.”
Very handy, also interesting to see the difference between today’s “hi-def” and the future’s 4k standard. Take a look at the pixel differences! That’ll make you hate yourself for spending all that money on a 1080P monitor when 4k starts coming out!

I was working on a computer with a bunch of viruses / malware on it (it had no A/V previously) and a bunch of things were messed up. No firewall, no windows updates, network stack wouldn’t start, etc. etc.
One of the things on my list was to get windows updates to work again, and apparently one of the viruses enabled a proxy server for windows update and it changed it to some weird port (obviously a tactic of the virus to disable / re-route windows update traffic).
This is how you reset the windows update connection settings back to the default (no proxy server).

If you have a windows XP installation CD / DVD, and you’d like to know if it’s OEM, Retail, or Volume Licensed, take a look here to find out:

I’ll try to hunt down the same info for Windows Vista, and 7 as well.
