Microsoft Finally Decides to Put NTLM Out of Its Miserable, Ancient Existence

Well, it only took a few bloody decades, but Microsoft’s finally decided to disable NTLM by default in Windows. About damn time. NTLM – that crusty old authentication protocol that’s been hanging around since dinosaurs roamed the datacenter – is finally getting the axe. Apparently, someone at Redmond woke up, sniffed the 1990s security stench wafting off their codebase, and said, “You know what, maybe letting people use this fossilized crap for logins isn’t a *good* idea.”

Instead, they’re pushing everyone to use Kerberos and the new, shiny IAKerb setup. Sounds nice, until you realize all the poor admins are now going to have to sort through a mountain of legacy shit systems that still rely on NTLM. Because, let’s be honest, there’s *always* that one critical line-of-business app held together by duct tape and prayer that will implode the minute NTLM disappears. And when it does? Guess who’s going to get screamed at by management and their “security-first” compliance team? Yep, you. The sysadmin who didn’t invent this garbage — just inherited it like some cruel joke from the ghosts of IT past.

Microsoft is nice enough to give everyone tools and telemetry in Windows to help track NTLM use before it’s completely turned off. Because, sure, nothing says “fun weekend” like scouring log files the size of a Tolstoy novel trying to figure out which ancient service account is still puking NTLM requests into the void. Oh, and they swear this is all “part of improving authentication security.” Fantastic. Maybe next they’ll upgrade some other relics while they’re at it — like Group Policy hairballs or the Control Panel that refuses to die.

So, buckle up, update your policies, and prepare for the usual chaos. Microsoft is killing NTLM, and surprise surprise, it’s on *you* to clean up the bloody mess.

Once had a user complain their “network login” wasn’t working — turns out their machine was still authenticating with NTLMv1 in 2024. I told them to send a thank-you note to their great-grandfather who probably configured it during Windows XP SP1. Some people inherit money, others inherit technical debt. Lucky me.
