Désactiver #NetBIOS over #IP avec #PowerShell

La désactivation de NetBIOS over IP doit être systématiser en entreprise. Encore faut-il que les #sysadmins #Windows en aient la compréhension et les compétences.

Microsoft confirmed WINS will be removed from Windows Server releases following Server 2025, with support ending in November 2034. Organizations relying on NetBIOS name resolution are advised to audit dependencies and migrate to DNS/DNSSEC, conditional forwarders, or split-brain DNS.

This is an important long-term planning moment for IT and security teams maintaining older environments.

I've commented before how these two #Microsoft #Win11 machines can see everything on my lan ... except each other 🤦‍♂️

#CoPilot tells me this is a known issue and I can either activate #smb1 protocol 😱 or perform a simple 7-step work around, 🤔 basically enabling #netbios over #TCP

Wrapping a non-error-correcting protocol inside an error-correcting protocol, for you non-nerds 🤓 instead of using an error-correcting protocol alone, b/c someone just can't say goodbye to #novel #netware🦕💩🧟‍♂️

#1995

#NetBIOS, #Windows LAN-Manager ist eine Technologie aus dem Jahr 1983, die in modernisierter Form immer noch zum Einsatz kommt, wenn man auf freigegebene Windows-Laufwerke zugreift.

Werde einfach nicht verstehen und akzeptieren, dass diese Technologie auch heute noch unerträglich langsam und unzuverlässig ist, obwohl inzwischen selbst einfachste DSL-Verbindungen von zu Hause absolut besser und schneller sind, als jedes High-End-Netzwerk von 1983.

When #windows decides it's had enough of you blocking it's update/telemetry processes (going to wd-prod-cp-us-west-2-fe\.westus.cloudapp.azure.com) and just yeats out the lookup over #netbios 🤷
42 Years of Computing – Networking

I’m doing a retrospective of 42 years on programming, concentrating on how the various computer differ from the current ones. Today I will talk about networking. Networking these days reminds…

#TIL about user name formats in Windows

Anyway, I did what any underpaid college dropout would do:
• ask #IT for a few extra PCs on the LAN
• distribute the #cellular tower data across #Microsoft #Excel workbooks, one per machine
• write some glue macros to exchange data (probably using Network #DDE or #OLEAutomation)
• babysit the PCs as they inevitably crashed every few hours due to #Windows' flaky cooperative multitasking and its #NetBIOS Frames (then called #NetBEUI) networking protocol (6/6)

Podczas studiowania eksploita EternalBlue badacze Sean Dillon oraz Jenna Magius w czerwcu 2017 r. odkryli 20’sto letnią lukę w protokole SMB (ang. Server Message Block), która umożliwia przeprowadzenie ataku odmowy usługi (DoS) poprzez wyczerpanie zasobów pamięci wybranego komputera. Podatne są wszystkie wersje protokołu SMB (1,2 i 3) oraz systemy Windows 10 aż do wersji 2000 […]
