Welcome to Nervous Admin!

Hey everyone! My name is Jay Weier and I am the creator of Nervous Admin. Over the last 9 years I’ve been working as a Systems Administrator in NH. All Systems Administrators rely heavily on blogs and articles available via Google to do our jobs. So this blog is me trying to give back to that community by creating tutorials and publishing information on what I encounter in my day to day life.

I picked the name Nervous Admin with the hope that this site will help a nervous Systems Administrator become more confident in what they are about to do. It’s always nice to know that someone has done this before you and lived to talk about it 🙂
