Pstools freeware from Sysinternals
One problem with upgrading software remotely is that you often need to stop the software you are upgrading first. Often, there is no service that can be stopped. The process must be killed. This can be a bit nasty with Windows systems because there is no easy way to find all instances of a particular […]
Using Cygwin for Automated File Transfer
Although Windows 2000 can be set up using proprietary (Well… MSified) secure connections via IPSec, there are a variety of problems. Most notable is the difficulty to get secure connections to work across multiple platforms, even between different Windows products. It is quite easy to create keys and pull files securely over the Internet from […]

The Arusha Project
The folks at the Arusha Project are *extremely* caffeinated. The best way to describe this project is that it is a language that defines systems objects. The catch is that it can be specific and useful. You can actually do package management with it. If you are running Open Source software of any ilk for, […]

IT is, true, but define with the Microsoft Operations Framework
“It is.” is the best answer, really, my friend confided in me over a campfire when describing his and a friend’s 24 hours of trying to unravel the mysteries. I was selling CP/M computers at the time, and he was talking bigger than Information Technology. We all know that IT is as we look out […]
Disabling Shutdown Reasoning on Windows Server 2003
When you shut down or restart Windows Server 2003, you are required to explain yourself: The only way to shut down is to enter something in the lower box: Whatever. Makes us want to punch the screen in defiance, like when XP gently asks if you have forgotten your password. Now, you might think this […]
Creating a One Way External Trust Between Windows 2003 and NT (MMC)
To allow users in an NT domain to use resources on a Windows 2003 domain, you need to set up a one way external trust.
