Windows Update failed with the error code 8024402C

I have a very strict policy that servers must not access the Net. If a server needs to be accessible from the Net, it will be placed in the DMZ zone with very rigid firewall rules. To update all servers, I need to implement the WSUS server in the local network.

I never let servers update automatically. Rather, I let them notify me about available updates and then I will manually run an installation process.

Reading system parameters using WMIC

A few months ago, I had a need to find the serial numbers on a few servers. This number is printed in small size letters either on a tag or sticker placed on the computer case. In most cases, that sticker isn’t visible without extracting the server from the rack. Too much hassle!

Luckily, virtually every brand name machine has its serial number inside the system’s BIOS. We just need access to that information. So, the information is there, but we can’t read it easily. The answer is to use WMI.

Installation of IE11 failed with code 9C47

Recently, I found that one of the servers doesn’t have IE11. I was surprised by that, but OK. I never use IE (or any other browser) on any server. Additionally, most of the servers don’t even have the default gateway address.

I ran Windows update, it started to work….

Weird Task Scheduler error 0x1

If you’re a “poor soul” administering an Exchange server, then you probably know that it lacks some of the security features. I use the smart host solution at the front of the server to increase email security. However, I will explain the concept of smart host in another article.

Part of this solution is the Spam Assassin anti-spam engine. The key problem here was the scheduled task that is used to update the Spam Assassin’s definition files; it failed with error 0x1 and the reason was weird.

Building the “Windows To Go” flash drive

Many Linux installations have an option to boot from removable media, like a CD or USB flash drive. This solution is known as the live CD. Windows users did not have such an easy solution for years. There were some solutions, but they were either complicated to build or suspiciously legal.

Eventually, Microsoft introduced this option with Windows 8. This was the first time that even less experienced administrators (or advanced users) could build their own live Windows environment. Unfortunately, this solution natively supports only this short list of USB drives. But don’t give up!

If you are ready to get your hands dirty, here is a recipe how to build your own “Windows To Go” flash drive.

Increase memory for a stable WSUS work

In my recent posts, I described the problems with the inaccessible WSUS server. The first problem was related to the stopped WSUS database and I quickly solved it.

The second problem was more complex and I spent an hour narrowing it down to the stopped WSUS application pool in IIS. I found a temporary solution – to manually start the application pool every time the service crashes.

The WSUS database stopped

In the past few weeks, I had a series of problems with the WSUS server. It just stops. So, I need to check the server and fix the problem.

In most cases, I spotted the problem when I tried to update my laptop. While trying to check for new updates, I am getting one of the many update related errors. In this case, the error 80072EE2.
