How realiable is file recovery in microsoft365 in real use?

Hey folks,

been digging into how orgs handle file recovery in m365 (onedrive, sharepoint, teams...).

from what ive seen, most admins just rely on version history and the recycle bin, but i keep hearing about people losing stuff after the 93-day window, or overwriting important files with no rollback.

for those of you managing m365:

how often do you actually run into file loss that you cant fix with microsoft's built-in tools?

do you use any third-party backups, or just trust microsoft’s recovery options?

just curious how people deal with this in real life, any lessons learned or horror stories welcome.

Roadmap to Windows Server for a tech support at a school district

Our school district has about 30ish servers, one for each school. Using hyper-v a lot, about 180ish vms to run as file servers, papercut servers and etc. Now we are beginning to fully adopt Intune to manage our pcs, laptops and macbooks & ipads.

As a tech support, school visits and ticketing are not challenging, would like to grow into sysadmin role, especially hands-on experience. Would much appreciate a detailed roadmap for a windows sysadmin in a school district.

Besides pursing MD-102 and MS-102 certs, I really want to b11th Gen Intel(R) Core(TM) i5-11600K @ 3.90GHzuild a homelab that can help me to get familiar with the skills required.

I have a gaming pc (11th Gen Intel(R) Core(TM) i5-11600K @ 3.90GHz, 12 cores, 64gram, 4 T ssd, gpu 3060 12G vram), is this enough to build a virtual homelab for practice? Or I have to purchase the used Dell server, switches to build a physical one? Or is there a cloud playground for Junior windows sysadmin?

How are you actually tracking assets across 200+ remote employees?

We've gone from 50 to 200+ remote employees in 3 years, and our asset management has become a nightmare.

The main issues we're facing:
Employees moving between states/countries with company equipment Devices falling off our radar when people use personal networks No clear chain of custody when hardware gets refreshed or people leave Shadow IT purchases that bypass procurement entirely Recovery logistics when someone quits (especially international)
For those managing distributed teams:
How are you handling this?
What tools or processes are you using to maintain asset visibility at scale?

Anyone managed to get Cisco SmartNet for gear bought from the gray market?

Hey everyone,

Curious if anyone here has gone through this before.

We’re a small IT team running a few Catalyst 9300s and ISR 4Ks. Our local Cisco partner keeps telling us to buy everything new through them — otherwise “no SmartNet, no support.” The thing is, the quotes we’re getting are painful, and our budget isn’t keeping up with Cisco’s licensing changes.

I found a supplier outside our region offering brand-new, sealed Cisco gear. They claim everything’s legit — registered serials, no refurb, no grey tags — and they even offered to share serials for verification before purchase.



So here’s the question:

Has anyone actually been able to register SmartNet for gear that wasn’t bought through a local authorized Cisco partner? Does Cisco really reject SmartNet for gray market hardware, or is it up to the partner handling the request?



Not looking to do anything shady - just trying to keep the network healthy without breaking the bank.

Would love to hear from anyone who’s dealt with this recently.

Just now bombed my HPE6-A86

Hello,

I just now failed my Aruba Exam, I learned with the study guide from the previous exam and had a Course 2 months ago to prepare for the Certification.
How would you recommend to me to learn for it, I failed with 50 percent.
There were questions that I had never seen before and didn't really understand. It was my first real Exam besides ITIL that I did.

Microsoft Issues - Teams/Outlook/Sharepoint?

I know there was an outage around 4 5 days back, looks like we are still getting some weird issues.

In particular.

\- When trying to get into sharepoint files across different locations it states invalid, will randomly start working again after a certain amount of time

\- Teams messages/photos not sending and just stuck on spinning?


Anyone else experiencing any of the issues, I am based in europe.

AI Rant

Ok, it's not like I didn't know it was happening, but this is the first time it's impacted me directly.

This morning, before coffee of course, I over hear one of my coworkers starting OneDrive troubleshooting for a user who does not have OneDrive. While they can work with OnrDrive in a quazi-broken state, it will not fix the actual problem (server cannot be reached), and will get annoying as OneDrive is left in a mostly broken state. Fortunately I stopped her, verified that I was right and then set her on the correct path. But her first response was "But AI said..."

God help me, This woman was 50+ years old, been my coworker for 8 years and in the industry for a few more. Yet her brain turned off *snaps finger* just like that… She knew this user, and that whole department, does not even have OneDrive and she blindly followed what the AI said.

Now I sit here trying to find a way to gracefully bring this up with my boss.

Company is increasing employee count four fold- what are some 'musts' for evolving IT practices / implementing new policies and/or platforms?

Basically just the topic noscript- what are some innovating approaches to new systems, policies, employee/customer engagement that a small IT team can think about when a company is expanding like this? What sort of things have you guys implemented that made a big impact to the work force, got you pats on the back, etc.?

Thanks for your time!

Production manager says MFA is causing production personnel to get distracted on their phones—he wants alternatives or MFA disabled

Production manager says when employees pull out their phones to accept MFA requests, they get distracted by notifications and spend more time on their phones that what he sees as acceptable. When employees are called out, they blame MFA for having their phones out. He's gone straight to the CEO, who is overreactive to productivity complaints.

They are asking IT if we can disable MFA for these employees, or make it so a phone is not required. Why are management issues always turned into tech issues? It sounds to me like there is a lack of discipline in that department.

CEO luckily understands the ramifications of disabling MFA, so he is not urging us to do so, but the production manager is still insisting something must be done.

How are you transferring PC files from old to new PCs in 2025?

Is OneDrive sync the easiest way to do this, or is there another tool that moves things over without too much hassle?

Randomly SSD not found - users get PXE boot prompt, reboot "solves" this

I seem to be seeing a rash of these across laptop models, more on ThinkPads than anywhere else over the past 6 months or so. The issue seems to be the SSD is not seen at boot causing the laptop to attempt to PXE boot. Power cycling the laptop seems to resolve this, but it eventually comes back. Laptops seem to have no other issues. Once running, they run fine.

I had been hoping it was a firmware issue that would be resolved, but it's still happening several months after we first started seeing it. Laptops are all new, ie within a year to 18 months old. Vendors (Lenovo, Dell) want to swap the SSD and start fresh. Users are hesitant because of downtime and needing to use spares that are 3-4 years old, so painfully slow by comparison.

Before we start replacing SSDs, has anyone else run into this and have you found a fix?

USA-based Admins: How do you negotiate a wage?

I am moving to the USA. I have a job offer that's median-low for "IT Engineer" (Win+Linux+AWS). What I don't know about is benefits. Do you negotiate that too?



i.e.
They might offer good Vision+Dental but poor medical (drugs?).

So do you counter-offer to improve those things too?

How does the average non-dev negotiate your salary?

Need office hoteling software recommendations (desk booking conflicts)

Our company went "hybrid" a couple of months ago (downsized our office space by 40% but they still expect everyone to come in most of the time) but desk booking conflicts are proving to be a bit of a problem.

I've been tasked with finding some kind of ‘office hoteling’ software (which I think is just a fancy term for desk booking? Please correct me if I’m wrong!)

I've been Googling but frankly getting a little overwhelmed, so wanted to ask what are you all using? 

Ideally we’d like something that either integrates with Slack or has a mobile app to make this more convenient for folks.

How do I permanently fix "trust relationship failed" errors on domain-joined laptops connecting via VPN?

Looking for some help with a recurring issue that's been driving us nuts. We're an MSP and have a client with a relatively simple setup, but we keep hitting the same problem.

The client has a single office with a Windows Server 2019 Domain Controller. They've got 4 desktop PCs and 4 laptops. Two of the laptops are for hybrid workers, and the other two are for fully remote employees who never come into the office. Remote users connect back via SoftEther VPN.

Here's the issue: only the laptops are getting the "The trust relationship between this workstation and the primary domain failed" error. The desktops? Never have this problem.

What's really strange is that it happens both when laptops are connected via VPN and sometimes even when they're on the same WiFi network as the DC in the office.

When it happens, sometimes a reboot fixes it. Other times users just wait and hope it sorts itself out. If a user brings their laptop back to the office, plugging into ethernet sometimes helps. When none of that works, we end up unjoining and rejoining the domain, which obviously isn't a real solution.

I'm looking for what we should actually be checking to solve this permanently. What causes the trust relationship to break specifically on laptops? Is there something about the VPN connection or laptops going to sleep that breaks the secure channel?

Any diagnostic steps or configuration changes we should be looking at?

Windows 10 LTSC 2021 End of life? What the hell, Microsoft?

Just got into the office, and immediately saw that some of our LTSC 2021 Machines show the ESU Message in Windows Update, telling me we are out of support and should update asap or buy ESU. This is a sick joke, right? Last time i looked, we have got a few years still - also it didn't report any updates for last patchday.

Thanks Microsoft, this is fun.

Anybody else having issues?

EDIT: Guys, this is about LTSC, which is supported for quite some years still. Not about Enterprise, Pro or Home.
