What would you do if your boss was fired, and your new boss was not handling the workload of the old boss? Specifically in a small team (3) situation, where the manager typically is willing to stand up and work tickets as needed, but the new manager who promised to be hands-on is simply not?

It's a very difficult situation as we are understaffed, which they acknowledge, but still refuse to even look at the ticket system. They want us to screen share it, or give verbal assessments of what our weekly focus was, as though they are above doing the work their predecessor did. In this small team, typically the breakdown has been helpdesk (little or no IT experience), sysadmin (mid-level), and manager (senior admin who now also manages IT staff). This new leader is acting like they're in a huge company with a department of 10+ people, like we can afford to have someone who doesn't cover, even when IT members are out on vacation or sick. What's the solution for us?

Also if there's any way to auto connect on a Set up Wi-Fi too, i don't know if any of this is possible, but i thought i might just ask anyway

Exchange SE install ends prematurely Event Logs: "Installation Completed Successfully" after cancelling first install.

Was trying to install Exchange SE tools only so I could shut down my last exchange server. During the install I was missing a prerequisite (.NET 4.8). So I installed that which asked for a restart. I closed out of the Exchange installer and restarted.

After restart, updates applied, etc...

Started the Exchange SE installer again. It went through the standard MSI installer "Gathering required information" then the installer just goes away.

Checking the Event log, I see these entries all within a second of each other.

>1040 Beginning a Windows Installer transaction: E:\\Exchangeserver.msi
1042 Ending a Windows Installer transaction: E:\\Exchangeserver.msi
11707 Product: Microsoft Exchange Server -- Installation completed successfully.
1033 Windows Installer installed the product. Product Name: Microsoft Exchange Server. Product Version: 15.0.2562.17. Product Language: 1033. Manufacturer: Microsoft Corporation. Installation success or error status: 0.

The logs in C:\\ExchangeSetupLogs are from the original installation attempt. I have checked the (suggested) registry for HKLM\\Software\\Microsoft\\ExchangeServer, there are no entries there. Control Panel does not show Exchange Server is installed. I also tried renaming the Program Files\\Microsoft\\Exchange Server folder. And of course, restart.

Guess I should have double checked the Prerequisites were installed before proceeding.

Any suggestions?

Can't seem to get the installer to come back up.

Office environment question

Going to lead off this post with a "Sorry I am not really a Sysadmin" but I do frequent (lurk) this subreddit and it has been helpful in the past.

I am a really informal tech leader at a mid-sized architecture firm. Before I arrived, much of the contents of our server were stored in the cloud, and for the past few years, and in the time I have been here, we have worked primarily with a server that is stored physically in our office, monitored by our IT service providers.

Do you think it would be worth returning to the cloud? We have been somewhat frustrated with our IT company as of late and have a previously good relationship with a company that does phone services that otherwise also could provide IT services, just via a cloud environment, that would virtualize a lot of our system. We could also tap into their broader cloud infrastructure, but I lack the technical know how to that extent to really get a sense of what is better - and most importantly if it is worth the money

Tl:dr 50-75 employees distributed in two office, should we have a physical server or work more in the cloud? I am leaning the later.

Company running VMware 5.5 in 2025

Found an enterprise running VMware vSphere 5.5 (from 2013!) with 500+ Windows Server 2008/2012 boxes. They're planning to upgrade to... VMware 6.x, which is.. yeah.

Someone should tell them about Broadcom pricing before they get destroyed. Yikes.

I keep finding companies like this, maybe 20-30 per week with seriously outdated infrastructure.

How do you even approach companies that are this far behind?

Hyper-V Issue – Weird but seems to be true

TL;DR: Could removing a DVD drive (not just ISO removal, actual drive removal) from a running Gen 2 VM cause a cluster host to briefly lose all its connections to everything?

So, I was doing some routine maintenance on our Hyper-V cluster (6 hosts, Nimble SAN) last week, live migrating some VMs, updating others and suddenly one of the hosts lost all connections to the iSCSI storage and the cluster. Some of the VMs on that host failed and rebooted, some did not. After a minute everything was fine.

I couldn’t figure out what happened, but 2 minutes earlier, I had, on a different host, removed a DVD Drive from a running Gen 2 VM because I couldn’t seem to migrate it from 2019 -> 2022 with the DVD drive attached. (Currently we still have some 2019 hosts)

I didn’t think much of the DVD drive removal as I was doing other maintenance and I couldn’t imagine it caused the problem and was running on a different host, but I did read later that you shouldn’t remove DVD drives while VMs are running, even Gen 2.

Two days go by, everything has been stable, I was doing more work and again removed a DVD drive from a running VM and again 2 minutes later one of the hosts lost its connections, some VMs rebooting, some not and again it recovered quickly.

So another day goes by and now I’m curious, I still don’t believe it was the DVD drive removal and assume it was something else I must have done, so I remove a DVD drive yet again from a different running VM and this time just waited and watched and sure enough, 2 minutes later, one of the hosts lost it’s connections to the storage and the network and then came back.

Again, I know now that you are not supposed to remove DVD drives from running VMs, but has anyone ever seen this and does anyone have any idea how or why removing a DVD drive from one VM could cause a host in a cluster to basically lose its mind for a minute?  I’m still not sure I believe it, but it’s hard to deny the pattern. This cluster has been running for years without ever glitching before.

Have you ever, as a system administrator, come across any organization’s business secret like I did? If yes, what is that??

As a system administrator you may have come across with any organization's business secret

like one I had,

Our organisation is a textile manufacturing one. What I came to know is, they are selling organic cotton & through which getting huge margin of profit compared to the investment for raw materials and production cost. Actually, they got certificates by giving bribes, but in reality, they use synthetic yarn... yet sell this as organic into the UK.
........... likewise any business secrets??

Why did APC jack up their prices so much before tariffs were even a thing?

As seen in this price history graph this basic ass 700VA (\~420W) UPS used to be under $120 in 2022, after 2023 it shot up and hasn't come back down. It peaked around $170 in the last few months. Is APC showing how greedy it is?

How are you automating compliance reporting at your company?

Hi everyone, maintaining SOX and PCI compliance across our partner network has been resource-intensive. We're spending too much time on manual audits, log collection, and meeting documentation - time we could've spent spent on billable consulting hours.

How have you centralized audit data and reduced the compliance burden at your company?

Glad to have left

I left my former employer just under a year ago. I was the IT Manager and senior sysadmin. Today I couldn’t be happier to have left. I was just told by a former coworker who sent me screenshots of users complaining, that the IT Director instructed my replacement to lower the maximum email attachment limit size from the 100mb I had set, to 8mb. That’s right. EIGHT megabytes. After an avalanche of complaints they raised it to 15mb, which is a joke by today’s standards. The complaints have been so bad the President got involved.

The reason? A handful of mailboxes (maybe 10) have reached their max 100gb size (E3 licensing). Rather than addressing the workflow of these individual users, implementing an archiving solution, or adjusting their retention policy, they came up with this asinine solution as the answer. This company does not have budget issues, just a misguided effort by a stubborn director who shouldn’t be in any place to make these decisions.

So glad I’m not there anymore because I probably would have died on that hill.

Edit: company was very behind in tech. So much of what they were doing was paper. They didn’t even have a way to pay for the service other than sending a check until 2020.

Found ghost machines that looked healthy

During an audit I saw devices marked active that had not reported in months. Some had been rebuilt, some were in storage, and a few were unaccounted for. That made me rethink how we age devices out. Have you cleaned up ghosts like this before?

NTLM V1 Found on servers during AUDIT

Hi everyone,

I’ve been auditing authentication logs on a set of Windows Servers (2015 and above). Most of the time, authentication is happening via Kerberos as expected, but I’m occasionally seeing NTLMv1 entries in the Security logs.

Here’s what I’ve found so far:


Event ID: 4624 (Logon Success)
Logon Type: 3 (Network Logon)
Account: ANONYMOUS LOGON (NT AUTHORITY)
Authentication Package: NTLM
Package Name: NTLM V1
Source Info: Shows a server name + source IP address

So basically:

These are Anonymous Logon attempts.
They’re falling back to NTLMv1 instead of Kerberos/NTLMv2.
The problem is, I can’t tell which specific app/service on that source machine is making these NTLMv1 calls

Please guide me how I can move from NTLMV1 to Kerberos or NTLMv2

Thank you so much.

September '25 Security Updates on DCs - secure certificate mapping enforcement - effect when DC is 2016 still

regarding "KB5014754: Certificate-based authentication changes on Windows domain controllers" -

Can anyone tell me please what the effect is on endpoints that have had a renewed certificate (with tag in san) that try to authenticate to a 2016 Domain Controller that has been patched to September 2025 level where strict checking is enforced?

I *think* it's that the DC will ignore and allow auth still, but I'm not sure I'm reading the resources right.
