Reddit Sysadmin – Telegram
How do you organize your personal How-To’s, bookmarks, and notes?

I’m curious how you guys keep your own technical notes, how-to’s, and small reminders organized. I don’t mean client documentation or project docs — I mean the stuff that’s only useful for you: those little commands, tips, and references you don’t want to forget.

Right now, my setup is kind of a mess. I’ve got a mix of OneDrive, iCloud, Firefox bookmarks, open tabs, Apple Notes, screenshots, and random files saved “just for later.” There’s a ton of valuable info in there, but it’s all over the place and I can’t find anything when I actually need it.

How do you handle that? Do you use tools like Obsidian, OneNote, Bookstack, or just plain folders and naming conventions? Did you build a system for yourself, or did it just evolve naturally over time?

I’d really like to bring some structure into all of this and make my personal knowledge base something I can actually use.

I am looking for arguments to get good ITSM, CMDB, RMM at my new job because my colleagues has no knowledge about.

I got a new job. The sysadmin managed computers alone for 3 years. He did everything to do
He doesn't give a damn about computer security. He prefers to take an obsolete computer without spare parts and turn it into a critical application server. He doesn't use Ldap or Active Directory. Users are just entered in an Excel file. The only thing he's interested in is making Python noscripts.He managed the computer system alone for 3 years. He did everything and set everything up to do as little as possible. And he manages the Windows computer system as if they were Linux computers using SSH access and raising the execution level to launch PowerShell noscripts. There is DHCP but he assigns fixed IP addresses without registering them in the DHCP.
He tinkers and tells nonsense so that the boss and users believe that he masters the IT infrastructure. He has never done any technology monitoring. He did not know GLPI and did not know how to use it. He is convinced that domain controllers are made to deploy software over the network.
I don't know how to argue for something better.
Honestly I lost all of my motivation. That guy has a really weird to do the job.

Pushing Windows Feature Updates

With the EOL for 23H2 around the corner, what are you doing to push out 24H2? I know this isn't a technical support forum, but I have to believe some of you have a good system for applying feature updates. Maybe Intune alone works for you, maybe you're using a deployment mechanism - whatever works, I want to hear about it because I do not want to manually update. TIA

Some background:

I can't seem to find a way that works. Intune, Powershell, GPO...

I've read that the main problem with feature updates is getting the 'commit' action to occur after installing them via noscript. This is what happens when I try to install it via powershell. Everything looks like it happens correctly, but then it hangs in an 'in progress' state. If I manually update the workstation using the windows updates control panel, it quickly progresses from download to installing to reboot in 30 seconds or less, so it's clear something happened with my noscript- but the final step is just not happening for some reason when I use a simple line like:

Get-WindowsUpdate -Install -AcceptAll -AutoReboot

I'm using group policy and Intune to define the target version. I've tried various PS commands including using PS-WindowsUpdate, the windows11installer, installing just the specific kb, doing all of these as system or as an elevated user...no dice.

Affordable DNS Filtering providers compared to OpenDNS

We are currently using OpenDNS (which was purchased by Cisco a while ago). Our account was the original Free tier Open DNS account which only allows for like 40 exceptions. Lately Open DNS has been flaky for one of the domains in the exceptions list and I have occasionally seen the domain resolve to an opendns block server as opposed to its actual destination and then a few minutes later flip again. I do feel Opendns has provided a reasonable amount of protection over the years however there is almost no flexibility in regard to troubleshooting advanced issues like this. Right now OpenDNS costs us nothing and i'm wondering if anyone here has made the switch to the cisco paid solution and what the cost is or another provider that provides reasonable protection. All of our Computers are pointed to our onsite DNS Servers which are pointed at OpenDNS if that matters.

I feel finally feel like a real sysadmin

I don't really have anyone to share this with but I just finished a migration of all our infrastructure from Hyper V to Proxmox with 0 issues everything is working and tested. Feels pretty surreal I genuinely shit myself when I was tasked with the migration I also done it on my own, I need to credit my boss for just leaving me to it, as previous bosses didn't show as much faith in my abilities.

I've been in IT for a decade and the last 5 years is when I started really coming away from the churn of tickets and making a forward path in my career, I get it though it's hard and company dynamics can really fuck up your career path especially the bullshit politics. I have had to make the leap to a new job a few times and urge anyone that isn't getting what they want if that's pay or equally the type work you are tasked with isn't giving you fulfilment PLEASE don't do a disservice to yourself go get what you DESERVE!

#DON'T GIVE UP ON YOURSELF

For anyone out there if you don't feel nervous you simply aren't going out of your comfort zone, remember to grow you 100% will feel out of place and yes it is normal to doubt yourself and feel like a total imposter I still regularly do!

If I could only go back and speak to myself when I was doing my first ever IT ticket ( was an AD Unlock haha! was absolutely terrified haha) and show myself what I would be tasked with and achieved I wouldn't have believed it.

Also please share your biggest wins/ achievements below I want to read them while I am enjoying a cigar and whisky tonight!

One Love!

Directive to move away from Microsoft

Hey everyone,

I’m currently planning to move away from Microsoft’s ecosystem and I’m looking for advice on the best way to replace Microsoft Entra (Azure AD).

Here’s my setup:

On-prem Active Directory (hybrid setup)

Entra ID is currently used for user provisioning, SSO, and app integrations (around 300+ apps).

Microsoft 365 (email, Teams, SharePoint, etc.) is being replaced with Lark/Feishu — that transition has already started.


Now I’m trying to figure out what’s the best way to replace Entra ID and other related Microsoft services — ideally something that can:

Integrate with my existing on-prem AD

Handle SSO and provisioning for SaaS apps

Provide conditional access or similar access control features

Offer an overall smooth migration path


Reason for the change:
The company is moving away from US-based products and prefers using China-owned or non-US solutions where possible.

Would really appreciate recommendations from anyone who’s done something similar — what solutions are you using for identity, security, and endpoint management after moving away from Microsoft?

Thanks in advance!

Full time offshore consultants

Hello,

My small (500 ppl) company is hiring a handfull of full time offshore consultants. Their agency will be providing the PCs. The company’s goal is for them to look like any other employee and they will need access to our network (probably just VPN client) and want them to be easily able to use teams chat, legacy file shares and other office collaboration with us. They mostly sit in the same office at their offshore company’s location, remote work may be occasional as well. I am not sure if the IT support from the consulting company is local or remote.

I am thinking that if at all possible I should push to have my orgs AV/XDR solution installed onto their machines, although I’m not yet sure if that is on the table (meeting next week). If I can then I am thinking we’ll be ok to join the PCs to our domain. And that I will provide them our office 365 licensing. I also could see us installing our MDM/remote access tool in addition to theirs (assuming they have one) as long as we are both not patching the endpoints.

Anyone with this experience can offer their advice? Has the consulting company ever outright refused your security stack? Technically they could work without joining the domain but it would make things more annoying/complicted. Without our security stack I would really have to lock down their VPN access a lot, yes I know something that should be done anyway, but not where we currently are. They can also technically chat and share between companies in office 365 but it’s far from perfect.

We are a very small IT team and I have the final say on everything IT and security. Thanks.

Next Steps after Endpoint Engineer

Hey everyone!

I’m looking for some advice from those who are or were Endpoint Engineers — where did you go from here?

A bit about me: I’ve been working as an Endpoint Engineer for about 4 years, with 10 total years in IT (starting at helpdesk and working my way up). I specialize in Microsoft Intune and SCCM, and we recently adopted the NinjaOne platform, which I’ve been exploring. I’m also the final escalation point for help desk and desktop support issues.

In my downtime, I create PowerShell automation noscripts to improve processes and remediate recurring issues. I’ve automated a lot of my day-to-day tasks already. With AI becoming more prominent, I’m trying to figure out the best next step in my career.

Any advice or insight would be greatly appreciated!

Thanks!

Looking for advice on sourcing affordable or donated networking equipment for students

Hey everyone,

I’m a new networking instructor at a small school, and I’m trying to build up our lab so students can get hands-on experience. Unfortunately, our budget for hardware is pretty limited, and I want to give them more than just virtual labs.

I’m looking for suggestions on where to find used, surplus, or donated networking gear like old switches, routers, cables, or rack equipment that still has some life left in it. I’ve checked eBay and a few government surplus sites, but I figured this community might know of better options or organizations that help schools get equipment.

If anyone here has been in a similar situation or knows of companies or programs that support educational setups, I’d really appreciate any pointers.

Thanks in advance for taking the time to read this. I’m just trying to give my students the best chance to learn the practical side of networking.

Windows 10 to 11 Upgrade via GPO

TLDR: Is it possible to upgrade from Windows 10 to 11 directly via GPO?


Hey all,

I'm currently working on getting our last few Windows 10 laptops in-place upgraded to 11 for some fully remote users.

Currently, we are asking users to perform the upgrade themselves, and with the exception of a few devices not being compatible, it's worked out alright.

To clarify, while we have a kinda sorta MDM, it doesn't perform OS upgrades. Neither do we have Intune or similar infrastructure/tools to automatically provide the updates. Additionally, we don't have a domain or any sort on on-prem resources that are traditionally found in a typical business environment.

While thinking about this further, especially since the deadline is fast approaching, I tried updating to 11 via GPO on a test machine and it seemed to work fine. Next I'll try remotely pushing the GPO via our ITAM system.

Has anyone else upgraded to 11 this way? Are there any gotchas that could prevent this from working?

a ticketing system that isn’t a pain to use daily

hi everyone, so every help desk tool I’ve tried feels like it was designed in 2005 and i am currently stuck between Jira Service Management and Freshservice, but both feel so bloated for what my team mates actually need. half my team just ends up DM’ing issues on slack anyway, and im over here trying to keep track of random tickets, half-filled forms, and email threads from 3 weeks ago haha💀

we are a mid-size team (around 300 ppl), so something super enterprisey is overkill, but I still need proper automation + integrations with our stack (Slack, Google Workspace, etc).

does anyone here actually likes their ITSM / internal help desk setup? also would love to hear what’s working for everyone who has one or if there’s a more modern tool I should check out thanks in advance peeps

How does IT typically handle a mass layoff?

Few months ago we had a round of mass layoff that pretty much caught everyone by surprise. One random morning all of us got pulled into a pre-recorded “meeting” with the CEO, who announced the layoff. Immediately after the meeting everyone received an email which either says you’re fired or you’re not affected, and by the end of the day those laid off were already removed from all our systems.

According to some of my sources there’s gonna be another round of layoff coming very soon, and it kinda got me curious: From a sysadmin standpoint, how are mass layoffs (and subsequent mass offboarding) typically done and how much time is needed for the planning and coordination? Also are there any places where I can find “clues” about who’s affected (e.g., Active Directory, distribution groups, etc)?

Is KodeKloud platform worth it for the Cloud Engineer path, and If not, what are better alternatives and why?

Hey everyone, hope yall doing great.

I’m currently learning Cloud Engineering and have been considering KodeKloud to strengthen my hands-on skills, especially for AWS, Linux, Docker, and Terraform.

I’ve seen mixed opinions online — some say it’s amazing for labs and practical DevOps/cloud experience, while others suggest there are better (or cheaper) options out there.

So I wanted to ask those of you already working in cloud or DevOps roles:

* Is **KodeKloud** actually worth the subnoscription for someone on the **Cloud Engineer track**?
* If you’ve used it, what did you like or dislike about it?
* And if not KodeKloud, what other platforms would you recommend instead (like A Cloud Guru, Coursera, Skill Builder, or others) — and why?

I’m mainly focused on getting real hands-on experience and eventually landing a Cloud Engineer role, so any advice or personal experiences would be really helpful

Thanks in advance!

Roll call - Windows 10 EOL

I run IT for a small (<100 person) org. With a week and change to go, here’s where we are:

- 50% of our machines are on Windows 11
- 20% of our machines are on Windows 10 but will (hopefully) be upgraded to 11 by Oct 14
- 20% can’t make the jump and will be replaced in the next week or so
- 10% can’t make the jump and will get ESU because they either (a) run well as is and this is a cost effective way to extend their life, or (b) are hooked up to ancient but critical hardware and it’s just easier to let those sleeping dogs lie

How are you doing?

PSA for non-profits: Windows 10 extended support is $2 for the first year on Tech Soup

This was discussed in the comments of another thread, but thought it deserved its own post.

Microsoft is not offering discounts on extended support for Windows 10, just a $61 fee through their volume licensing program that goes up in the second and third year. I just found, though, that Tech Soup has the licenses for $2/machine/year (going up to $3 and $5 in the second and third years). Not bad!
