Windows: Resolving the issue of locking out a user account in an Active Directory domain

A sudden locking out of a user in a domain on his work machine can usually be caused by previously saved login and password data for that account. In atypical cases, such information may be stored in the "SYSTEM" context. To find out and clear cached data, follow these steps:

1. Download and install the "psexec.exe" utility from the "PSTools" package.

2. Open a console with elevated privileges, go to the directory with the utility and run it with the following parameters: "psexec -i -s -d cmd.exe".

3. In the new console window that appears, execute: "rundll32 keymgr.dll,KRShowKeyMgr". The "Stored User Names and Passwords" settings window should open.

4. Delete all existing entries from there, close all windows and restart your computer.
