What are three things you must know to move from help desk to sysadmin?

My name's Jake.

I've been working in IT at an MSP for about a year now,

and this is how I was able to break out of tier one and move up to system administrator.

For those of you who don't know, an MSP is a managed service provider, so we give IT services to other companies.

So the first thing

you're going to have to learn in order to move up is how to read logs like a bloodhound.

I don't care if it's event viewer, syslogs, show commands, GP result,

You have to be able to read logs like your life depends on it because it does.

Logs are where the real answer lives.

You can look for things like security event logs 4625 failed logons.

Don't just look at the username look at these sub status codes and use GPT to make sense of them.

This is gonna give you a ton of information.

Group policy using things like GP result slash H is super clutch

because you can push that HTML file out to a place on the computer

and then analyze exactly what policies it's getting and what policies it's not getting.

You might see access denied, missing scripts, a GPO not being applied because of some security group.

You might use logs to look for DNS issues, bad forwarders, or stale A records.

Oftentimes you're going to find these things faster in logs than just pinging around aimlessly.

Now why does this matter?

Because at level one, you reboot and if it doesn't work, you escalate.

You do some basic troubleshooting and you escalate.

At the sysadmin level, you're responsible for finding the answer to the problem.

Not only do you investigate, you bring receipts.

You don't guess, you have to prove it.

Now, one of my first wins at sysadmin level was

when one of our company's core apps was not performing the way it was supposed to be performing.

It was dropping connections and running slow,

and I got into one of those very common situations where the vendor and seemingly everybody is blaming the network.

I was able to use tools like

Continuous Ping and WinMTR to prove that there was no packet loss or any real substantial latency.

We pulled performance data, got on multiple vendor calls,

rebuilt tunnels, and ultimately was able to work with them to show that it was a CPU bottleneck on their end.

This is when people start trusting you with the bigger stuff,

when you're able to find data and prove that it is or isn't what you think it is or isn't.

The second thing I think

you've got to know in order to go up to level

two to assist admin is you have to understand DHCP and DNS.

I know it sounds boring, but honestly, 90 % of weird IT issues trace back to one of these two things.

DNS, how your device actually resolves URLs.

So when a user types in portal .office .com, the device doesn't just automatically know where to go.

It's going to start by checking its local DNS cache.

Then it's going to hit its configured DNS server, usually your domain controller.

That's either going to help resolve the name internally or forward it externally to somewhere else.

So you need to know the difference between things like forwarders and root hints.

When your DNS server doesn't know the answer, where does it ask?

You need to know the difference between internal and external zones.

Is the name hosted inside your network or outside your network?

And then aging

and scavenging are going to be super important to things like cleaning up old stale DNS entries

because these are going to cause conflicts and issues.

And then DHCP is how IPs actually get handed out on a network.

Most devices, most of the time are not going to have a static IP set.

They're going to have one automatically handed to them by this protocol.

Your DHCP server is going to hand them out like a parking lot manager.

But if two cars get in the same spot, that's an IP conflict.

So you need to know how leases work and when they expire

and how they expire because they don't actually expire at the end of the lease.

They expire first at the middle of their lease, how to make reservations like for critical devices like printers or servers,

and then what causes conflicts like overlapping scopes or someone setting a static IP within a DHCP range.

Super duper important, something that we do all the time.

Let me give you a couple real world examples.

We used to have clients with the DNS server set to the loopback address, which is 127 .0 .0 .1,

because the old Cisco umbrella roaming client used this to resolve DNX or really to proxy DNS.

This causes all kinds of issues

because the umbrella roaming client is no longer a thing and a lot of devices still have that loopback address set statically.

So DNS just doesn't work and people say my internet doesn't work and then you have to go in and fix it.

I've also time and time again seen printers go offline because they have static IPs within the DHCP range.

Random drops and things will print and then they won't print and all these weird behaviors trace back to DHCP.

Again this stuff happens all the time.

So why does this matter?

If a user can't access his shared drive or Outlook keeps going offline

when they hop on the VPN or hop off the VPN

or a printer won't work sometimes or it only works after a reboot.

Probably DNS or DHCP.

So again, the help desk resets the nick and hopes for the best.

The sysadmin opens the DHCP console, checks the lease, reviews DNS records, and finds the source of the issue.

That's the difference.

And then finally, something you have to know to go up to sysadmin is scripting and automation.

If you're doing something more than twice a day, script it, period.

You can start with using PowerShell to create users.

And then we can automate report generation, exporting things to CSV.

We can use scheduled tasks to loop or batch process changes.

And when you're doing all this, absolutely use GPT and VS Code as your personal helpers.

We live in an amazing time where you don't have to read a book and actually learn PowerShell.

You can ask ChatGPT and it will give you a phenomenal answer most of the time.

So I wasn't some coding genius, but I learned early on that I have to use PowerShell to save myself time.

And scripting will do this for you.

It'll open up an absolute whole new world of productivity.

For me, the first time that I really saw this was

when I had to remove 20 contractors who were all fired at once from all of these distribution lists,

all of these groups, all these entra groups.

I could have spent hours clicking through AD and clicking through entra,

but instead I just wrote a few scripts using ChatGPT in probably 10 to 15 minutes

and got it all done at once.

I also use scripts all the time for log filtering now.

Again, I used to go to event viewer and click and filter for the logs there.

Now you can just write a PowerShell script and it'll find you the exact logs, when they happened, what you need,

and you can move on with your life.

100

And that kind of efficiency gets you noticed.

101

You get stuff done.

102

And a bonus thing you've got to learn is understand basic networking.

103

You don't need to be a CCNA or CCNP networking beast, but if you can learn to trace

104

and troubleshoot a basic networking issue to gather information before you send it off to the network engineers, it's going to level you up.

105

So you definitely got to know ping.

106

You got to know trace route you got to use ipconfig

107

and you got to use these tools to actually reconcile against the documentation you have.

108

So if you run a trace route and the trace stops at some certain place, you need to find what is that IP?

109

Is that one of our devices?

110

Is that a different device?

111

Like where is this traffic stopping?

112

That information alone is crucial.

113

You got to understand what a default gateway is

114

and you got to understand what VLANs and subnets are and how these things work,

115

especially if you're working in a place that's going to have segmented networks, which you probably should be.

116

And then also just understanding when to hone in on the switch versus the endpoint versus the firewall.

117

Always start with the endpoint or the switch.

118

All right, so if you're serious about becoming a sysadmin, it starts with these three, four skills.

119

Read logs, understand infrastructure basics, DHCP, DNS, and then automate the boring stuff.

120

And learn a little bit of networking.

121

If you nail those things, you're not just on your way to sysadmin work, you're already doing it.

122

And if you wanna actually build these skills, start labbing, make a test tenant at home,

123

mess with DNS, and use your buddy ChatGPT to write some baby PowerShell scripts.

124

It doesn't matter if it's perfect what matters is that you're not waiting for permission from someone to start leveling up.

125

This is stuff you can do on your own.

126

And in IT in general, doing the work before someone actually gives it to you is the biggest factor for leveling up fast,

127

speed running the tiers, and going from zero to IT hero.

128

If this helps you guys, drop a like and a sub if that's your thing.

129

Really appreciate you guys.

130

Have a good day. Be safe. Be smart.

131

Make some good decisions.

132

Start leveling up.

O que é a Técnica de Shadowing?

Shadowing é uma técnica de aprendizado de idiomas com base científica, originalmente desenvolvida para o treinamento de intérpretes profissionais. O método é simples, mas poderoso: você ouve áudio em inglês nativo e repete imediatamente em voz alta — como uma sombra seguindo o falante com 1-2 segundos de atraso. Pesquisas mostram melhora significativa na precisão da pronúncia, entonação, ritmo, sons conectados, compreensão auditiva e fluência na fala.
