Seriously? Still Using NTLM in 2024?

Ugh. Fine, I’ll summarize this for you people who apparently haven’t upgraded since Windows XP. Microsoft is *finally* getting serious about killing off NTLM authentication – and good fucking riddance, honestly. They’re introducing a new registry key, BlockNtlmV1Sso, and corresponding Group Policy settings to control whether systems even *attempt* to use NTLM for Single Sign-On (SSO).

Basically, if you set this thing to enabled (which you SHOULD), it stops Windows from automatically using NTLM when it thinks it can. This forces Kerberos – which is what you should be using anyway. They’re doing this in stages, starting with a warning phase and then moving to blocking it outright. There’s also some crap about auditing events so you can see who the laggards are still relying on this ancient protocol.

The article details exactly *how* to enable this via registry edits (for those of you too lazy to use Group Policy) and through the Local Security Policy editor. It’s all pretty straightforward, even for… well, never mind. Just read it. It also covers how to check if your systems are affected.

Look, just migrate to Kerberos already. NTLM is a security nightmare. This isn’t new information. If you’re still using this, you’re asking for trouble. Don’t come crying to me when you get pwned.

Seriously. Get it done.

A Related Story of Pain

I once had to deal with a company that *insisted* on using NTLM because their ancient, custom-built accounting software “didn’t support Kerberos.” Didn’t support Kerberos. Like they tried to rewrite the laws of physics. Spent three days trying to get it working, only to find out the problem wasn’t the software…it was a misconfigured firewall rule blocking port 88. Port fucking 88. I swear, some people just want to watch the world burn.
