A big thanks goes out to the obligatorymoniker and his script for programmatically adding IP restrictions to IIS6. I was looking for a better script to add IP restrictions. My previous script added the restrictions one IP range at a time. This script was adequate for a small number of IP restrictions but recently I was asked to add IP restrictions for every country we do not ship to. We had credit card fraud transaction from one of these countries and the boss was mad. After using Perl and a CIDR to merge the adjacent networks, I still had over 18,000 IP ranges to deny. Using my old script I tried to add these IP ranges to our test system this took over an hour to load. Your script loads the ranges in a couple of seconds.

It has been a long time since I actively worked with Microsoft’s ISA Firewall so it took me some time to fix this problem. Buy.com periodically offers a 3 computer version of McAfee at a very cheap price. Since I am somewhat ambivalent about the merits of one virus checking software over another, I bought [...]

I found myself troubleshooting a Verizon PC5470 wireless broadband issue today. This setup worked a couple of months ago when I last touched it.

I had not looked or touched my “dogfood” server in a long time. It appeared to be happily doing it’s thing. Appearances can be deceiving. I found that my scheduled jobs were not running according to the schedule. I had about a dozen jobs with the “Could not start error” message. What a mess! I [...]

For the self-reliant, a third Windows desktop option emerges: Build your own “Frankenvista” on Windows Server 2008 I guess the transformation is nearly complete. Windows Server 2008 has almost completely embraced the Linux model of one code base for servers and workstations. It is the incompatibilities that drive you nuts.
