Ransomware such as Crypto Locker or Locky and other names are becoming more and more of a plague. Only in a few cases is it possible to restore the encrypted data. Without a backup, the damage can quickly become very extensive. Since the Trojans usually start encrypting data from a client and in doing so ... Read more

But as is the case with "just quickly": Here is the text of the error message: Error: The following error was generated when "$error.Clear(); Install-MsiPackage ` -PackagePath ([System.IO.Path]::Combine($RoleLanguagePacksPath, ...

Here is another small script from the Quick and Dirty series. The script was actually created to monitor an AntiSPAM gateway, which was often overloaded and no longer processed any mails. Unfortunately, "text-only" mails without hyperlinks or other content turned out not to be very meaningful, because they were practically always ... Read more
I stumbled across an interesting problem with an Exchange 2016 server. This ASP.NET event 1310 kept appearing as a warning in the event display in the application log: Here is the abbreviated error message: Event code: 3008 Event message: A configuration error has occurred.
