Feeling Like a Fraud

Posted by ItsColeman12@reddit | sysadmin | View on Reddit | 174 comments

I am an IT Systems Administrator at a company of ~500 employees. I am the sole IT worker. I started there as an IT Technician, but after my coworker left, they promoted me to IT Systems Administrator, no interview or anything. They then closed my old position, leaving myself as the only IT staff.

I graduated college less than 2 years ago and am now tasked with maintaining and updating this 24/7 infrastructure. I feel that there is too much for me to do and I cannot learn fast enough (I understand that this is a pretty common mentality in IT). Even as a Systems Administrator, I feel I have a very rudementary knowledge of Networking and Active Directory.

Can anyone give me any advice on how to work on these skills? Unfortunately, as I work on my own, I do not really have the opportunity to learn from someone senior to me.

I understand homelabbing is how most people learn, I just don't really know where to start at this point.
