The Case of low Disk Space on Windows Server R2 File Servers – Enable Dedup – #MVPHour

Hey Checkyourlogs Fans, Today, we have a quick post just reminding you that if you have Windows Server 2012 R2 File Servers are not able to migrate them to Server 2019 yet.

Ping Sweep Using PowerShell -Quick and Dirty – #PowerShell #MVPHour

Hey there fans! Today I needed to ping sweep an entire subnet from a Windows Server 2012 box. Simple, right? There are plenty of free and paid tools out there ready to perform this task. My dilemma was, and is, I don’t want to install additional software, no matter how small and tight, on servers. Especially anything requiring additional licensing or support software such as, GASP, JAVA. Nope, nada, not on my watch. Keep server configurations clean and concise is my motto. What to do? My need still existed, and oh, by the way was fairly urgent. PowerShell...
