When I go on-site to teach a WorkshopPlus, the number one call generator for helpdesk is “Account password” reset or “Account Lockouts”.
It’s also common to go to environments where the threshold for bad password attempts is set to 3. That is very Windows XP/7 or Windows 2003/2008/2008 SP1 numbers.
Q: What is the recommendation nowadays (Windows 10/Windows Server 2016/2019)?
A: “We have selected a threshold of 10 bad attempts, a 15 minute lockout duration, and counter reset after 15 minutes (10/15/15).”
For details, please go through Aaron Margosis blog post:
