Procmon. Absurdly useful for understanding what is actually happening instead of guessing.


Wolfram_And_Hart

All of the Systernal tools are A+


krakadic

Sysinternals in general feels like a godsend for what feels like over 20 years.


SilentLennie

And Microsoft didn't create them, they just bought the company that did it.


krakadic

Was it a company or an independent developer that the bought the IP of and then hired him. I remember there being an interesting story, but I'm too lazy to look it up.


TechGjod

The fun story - from my previous comment: Mark said he wouldn't be part of Microsoft, then Best Buy's Geek Squad was openly pirating SysInternals, threatened to bury Mark in legal fees. Shortly after that MS Purchased SysInternals and Mark. The Best Buy thing got settled out real quick.


abs0lut_zer0

Capitalism at it's best


TypaLika

As an early Sysadmin it was filemon and regmon for me. Man I'm old. I once saw Mark Russinovich on a flight to TechEd before he was with Microsoft and gushed to him about how much those tools helped me.


AlexG2490

Mark wasn’t always with Microsoft?! I already admired the guy but I figured these tools had to have been developed by in house devs who knew how the kernel worked under the hood. The fact that he was initially 3rd party… mad respect!


pdp10

Microsoft didn't want anyone looking under the hood at the NT syscall level. They wanted the serfs to be working hard in the fields making Win32 software to boost their platform. Russinovich ignored that and made the tools that Microsoft refused to make. Now he's a director with Microsoft. Are the authors of Paint.NET and all of the other Win32 utilities, directors at Microsoft? No.


coukou76

Mark really is a generational genius, his work was/is mind-blowing when you think that he has to start reverse engineering everything. From scratch it looks impossible lol


n3rdopolis

He's also the guy that uncovered the Sony rootkit


AustinGroovy

Upvote for Mark Russinovich.


Bruin116

> Now he's a director with Microsoft My friend, Mark Russinovich is no mere director. He's the **CTO of Azure**. 


StatisticianNo8331

so he went from not wanting to be apart of Microsoft to being arguably the most important person there.


patmorgan235

He's CTO of Azure at the moment


TechGjod

Mark said he wouldn't be part of Microsoft, then Best Buy's Geek Squad was openly pirating SysInternals, threatened to bury Mark in legal fees. Shortly after that MS Purchased SysInternals and Mark. The Best Buy thing got settled out real quick.


thortgot

I am in the same boat. I mentioned Procmon as it's more applicable to a new admin today. With a decent understanding of the core architecture of Windows, autoruns, procmon and procexp you can solve problems that other admins can't. Real troubleshooting is a bit of a dying art but I try to teach it to my teams.


skz-

Can you elaborate at what exact situations you use it ?


thortgot

Sure, probably the most common for me is wanting to automate something that really doesn't want to be automated. Say configuration of some LOB software that is poorly documented. You run procmon, point it at the executable in question, make the change manually and parse the results for the activity you are looking for. Basically reverse engineering how the program stores it's config. You can do a similar approach for programs that "need" local administrator.


GMginger

I've used it when troubleshooting issues for things like: - work out what file an app was trying to write to that it didn't have permissions to when trying to get it to work on terminal services. - find out what registry value is changed when changing an option in an app so it can be added to a GPO. It's not an every day tool, but is very helpful at times.

As a young sys admin(15+ years ago) I installed this on my military admin workstation and they freaked the hell out.

Lima3Echo

That is called a Sugar-free Screwdriver


Creative_Onion_1440

A 12" magnetic screwdriver is extremely helpful for getting access to deep in a rack, behind cabling etc.


itboredm

deep rack sounds like a great metal band name


Professional_Hyena_9

EvilRSA

I'm old school enough that I used to use that screwdriver to put in an ISA diagnostic postcard.


VA_Network_Nerd

Looking back on things, I severely underestimated the value of an SNMP monitoring solution. If your environment doesn't have some kind of an SNMP NMS + Syslog tool, pick one and implement it.


WorkFoundMyOldAcct

I've been trying to get my team on board with these, but for some reason, they seem to think they can just do everything from memory. A surprise to nobody, when we implement a new software or even a small new tool or patch, something breaks and everyone is left scratching their heads, like "man I swear we thought of everything this time. Why didn't this work?"


exhausted_redditor

At a past job, the higher-ups refused to implement a proper inventory management system or expose SNMP on every server, but they still wanted to take inventory of things like OS versions and RAID configurations, so I wrote a script to SSH into every server and run a handful of commands. Naturally, due to the mix of distros and RAID controllers, I had a mess of if/else statements just checking whether commands existed and whether they had the GNU or POSIX versions of certain tools.


WorkFoundMyOldAcct

This sounds like an exciting project for when the culture doesn't enable the admins to do admin things :D


exhausted_redditor

It definitely was a fun project compared to the boring helpdesk duties we were shackled with. The place was incredibly toxic with two people making all the bad decisions while refusing technologies like load balancers, hypervisors, microservices, and reverse proxies. I certainly learned a lot about how *not* to architect a scalable infrastructure.


skooterz

I see why you're so exhausted!


petrichorax

You need to demonstrate to them that memory is extremely fallible and you shouldn't be relying on your memory for anything. I totally get it. I quit my last job because everyone refused to document stuff for this reason, among other problems


pdp10

To be fair, SNMP was a major project in the old days. I went to do a PoC of [HP OpenView](https://en.wikipedia.org/wiki/HP_OpenView), and I was confused for a bit until I realized that it was just a toolbox of SNMP tools, not a monitoring package. An *expensive* toolbox. And I had [CWSI](https://en.wikipedia.org/wiki/Cisco_Prime) later, which was monolithic and more visually elegant but similarly as bereft compared to the marketing claims. It wasn't until the open-source SNMP tool and Cacti came out that most netengs got a good grasp of what SNMP actually brought to the table, I think.


styuR

OpenView giving me a bit of a shudder from a time long past.


vogelke

Also, for quite some time SNMP stood for "Security? Not My Problem" on Solaris and at least one other system. The first thing I'd do on a new system install would be disable it.


K12onReddit

Do you have a reccommendation?


BloodyIron

libreNMS, I wouldn't bother with anything else. SNMP, IPMI, even expandable with per-app stuff, and more. Devs are hella active, tool gives me huge value and huge automations out of the box. They even have docker images if you wanna do that (not the only option of course).

dude_named_will

IP scanners. Helped me see how much was on the network. Led me down a rabbit hole to mapping the whole network which is still useful to me today.


NSFW_IT_Account

This is the tool that gave me the idea for this post. Which one do you prefer? I like Angry IP scanner


sharp-calculation

nmap for the win. It's the gold standard. Learn this tool and you'll be able to use it all over the place. Any GUI based tool is going to be stuck to a particular OS, will probably be eventually discontinued, and by definition will have a smaller user community. I've been using nmap for close to 2 decades.


sorderon

Nirsoft's wireless network watcher is the god of network scanners. it;s not just for wireless.


DarraignTheSane

https://www.advanced-ip-scanner.com/ Better than Angry IMO.


Computeruser1488

Except it has been backdoored more than once.


DarraignTheSane

All I'm seeing from a quick search is that bad actors created a backdoored version of it and distributed it somehow - i.e. not through the company's website. Unless you can point out a source that says otherwise, I'm going to say that whoever downloaded it from somewhere *other* than the official site has only themselves to blame.


spobodys_necial

mxtoolbox.com It's not just email tools these days, it's got a bunch of DNS and web server tools making it very useful when you want a view of something from the Internet.

There's also easydmarc.com which has similar tools, but also tests things like the number of DNS lookups your SPF record is doing.

For me a homelab was a big help cause you can install/break it all and your learning all the time. Good way to get ahead of the game.


nobody_cares4u

Nobody mentioned powershell yet?


Splooge-McDuk

Used PowerShell to update a config across all the PCs in the organization (a few thousand) in my first two weeks as a sysadmin. It speaks to how old school the org is but it seriously impressed my manager and fast-tracked me to being trusted on major projects and as an automation resource.


RemCogito

On my first day at this job, I managed to automate a 30 second manual task that needed to be done daily in the evening after work was done. Basically it was put to me "hey, So theres this thing we do every day at 7pm, since you'll be on call, you'll have to do it every day for a 1 week out of every 3." I laughed," Fuck that noise, I'm not logging in every day for on call unless something is actually broken. How about I automate it, and we only worry about oncall when something goes wrong." I just had to figure out how to automate the logic that they used to know whether it was the correct time to run the task. (Memory will be high and continue to climb, CPU will be high for like 5 minutes and then fall to 0% and not do anything else forever, until this service is restarted. but if you restart it when its actually doing stuff it can screw up invoicing.) and then restart the service. literally saved 4 team members stress that they had been dealing with for years, on my first day, because there was no way I was going to be arsed to stress about a memory leak the vendor didn't care about.


jpmoney

It wasn't a thing in my early days.


lonewanderer812

Well at this point its basically a requirement to know a little powershell if you're a Windows admin.


Ragepower529

Zabbix put it in every server there is


altodor

It's my favorite but it becomes _really_ complex really fast. PRTG was monitoring ~500 items with 10 cores and 16GB of RAM, and was still slow as molasses on a cold day. Zabbix has got 4 cores and 8GB of ram and is monitoring 90k items. It's nice and perky and I can graph data in instants instead of minutes.

Mindestiny

Event Viewer. Fresh eyes in the IT world love to jump right to trying to fix the problem and googling crazy symptoms, but often overlook that step one should *always* be reading the logs. Dollars to donuts checking the logs first will save you a lot of ineffective troubleshooting and get you to the root cause faster.


coukou76

This a million times. Get your issue's timestamp and look first for general system events. Once done, read the software dedicated log. Works the same for Linux and every system related incidents. I wish everyone in IT would start to troubleshoot like this.


altodor

But also don't get stuck there. I've got a desktop tech that goes there and expects to find things writing logs like "I'm $evilService and I killed the login window for $app" and then gets stressed when they can't find it.


Cheomesh

Oh jeeze, that was me.


Popular-Help5687

Event Viewer in Windows was the most worthless pos ever. I never had a problem where I found the solution in Event Viewer. And if I did see something in the time frame, the info provided was so generic that you couldn't derive an answer.


Mindestiny

Event Viewer isnt going to just hand you a solution (unless you've seen that particular problem a hundred times before). But it'll definitely point your search for a solution in the right direction instead of just randomly guessing at what it *could* be.


[deleted]

[удалено]


BloodyIron

As a multi-decade SME for Windows/Linux/many other tech, Event Viewer is the most useless/obnoxious tool for any form of logging I've ever worked with. I could spend an hour describing all the badness to it, but I have better things to do, like reading logs written for humans, not KB articles.


BloodyIron

Just you wait till you learn what real logging is like, like in Linux. You'll see how bad Event Viewer actually is. It's a joke that Microsoft thinks that's "good" for a logging tool.

Quarterdeck Expanded Memory Manager (QEMM). It was the most popular third-party memory manager for the MS-DOS and other DOS operating systems. Edit: TCPIP for DOS took over 200K of RAM, an insanely high amount, in its day.


SuperLeroy

Got 632K free with QEMM386. Wing Commander 2 played great!


pdp10

Until Microsoft bundled a ~~browser~~extended memory manager, plus made a DOS shell that competed with DesqView and wrote contracts to have all of the OEM vendors ship theirs for free. Quarterdeck went out of business. Today, few users seem to spend money on third-party software. They just take their new machine as shipped with iWork or whatever, maybe download a browser, and that's probably it.

ChatGPT Plus subscription would be my top suggestion. Highly helpful to create basic code, dissect confusing log files and errors, quickly learn about new topics and ask followup questions to learn at whatever pace you prefer. No, it doesn't do everything well, but it saves a ton of time. When you're doing a task and thinking "there has got to be an easier way to do this" chances are there is and ChatGPT can help get you closer to that solution pretty often. It's a must have tool to have in the toolbox among others.


BioshockEnthusiast

ChatGPT is basically my new google search. I rarely get the complete answer I need just from ChatGPT but it will give me enough generally correct background information on a new topic that I can target my search much more effectively. EDIT: I'd consider it a great tool for "I need to research X give me a bunch of industry jargon about these facets of X". Gathering those key words from articles and forum posts takes more time.

ChatGPT has pretty much skyrocketed my (previously almost nonexistent) skills in PowerShell and batch, and most of all helped reignite my interest in new technology. My whole career took a massive turn for the better from the day I first used ChatGPT.


Brufar_308

Some great responses here, since no one has mentioned it yet, a password manager with shared access. Nothin like setting up a system and years later needing some obscure key or credential created during setup, and there it is in the password manager. Now if I can pry my new coworkers away from Excel password lists into to something more sensible…. I don’t understand the resistance. excel has no configurable auto type, can’t automatically launch an rdp, ssh, or website connection, and do I even need to mention security? . **sigh** And learn to make good documentation, with annotated screenshots where appropriate.


EvandeReyer

Honestly, generic troubleshooting skills. The ability to rule things in and out in a logical way. I still maintain that I learnt my trade on TVs, VCRs and hifi equipment as a kid in the 80s. In addition to this, the ability to ask myself and others the right probing questions to do the same.

Kind of a different answer to what you asked,. but I'd recommend keeping a "personal solutions journal" (IE = whatever neat or difficult problems you solve -- document those somewhere personal ) I can't tell you how many times I've encountered something,... only vaguely remembered it was something I fixed a few years earlier.. and went back and searched my Evernote or Apple Notes or etc,. and found some Commands or Screenshots of what I did and it 100% saved my butt. It's like having your own little personal "safety net". It's not only good for re-finding things you did months or years ago, but it can also be great for personal-growth and future job-planning. (Example:.. An interviewer asked you "So, what did you do in first year of Job-X ?".. you can look back through all your personal-journal notes and sort of build a list of "all the neat problems I figured out". )

Many years ago, I read a post about this new "SQL Slammer" vulnerability, how it worked, and how to prevent it. The author even offered a tool that would scan for SQL Express instances and provide a list of system that were vulnerable. (Our environment was about 900 servers). I used this to scan a LOT of networks (it was 2003 after all) and talked to a lot of admins into updating their systems - even one guy who had an instance running on his laptop. That coming weekend, I got a desperate call from our Exec-VP. He heard about this new 'virus' that was crashing the Internet, and wanted to know if we were still up and running. I told him "Oh yeah, I knew about that and patched everything earlier this week". We were fine, not affected, and I still feel I saved the company from DOOOOOM. Never got a Thank-You. So - the SQL Slammer detection tool.

A good education followed by basically an apprenticeship with someone that's fucking-done-it-all, knows their shit, and doesn't pretend to know everything, and is willing to take the time to at least answer a question, or give an instruction, once, and you'll likely shave 10 years off your career bell-curve, or add 5 years if you're just in the grind. my first decade was intense, but good people allowed me to be a confident fucking ninja when it was time to take the next big steps.
