Reset all user passwords within an ou to the same password
A quick and easy way to reset all the passwords for users in a particular OU is to run the following command in a command prompt window on the domain controller. The below will reset all the passwords to “password”. Change your OU references to your own settings.
C:\>dsquery user OU=tech,OU=australia,DC=waynestorey,DC=com | dsmod user -pwd password
If you have more than 100 users within that OU then use the following command changing the number after -limit to a number greater than the number of user objects
C:\>dsquery user -limit 100 OU=australia,OU=tech,DC=waynestorey,DC=com | dsmod user -pwd password
