I get error: Your password must be at least 0 characters long.

A. If you have enabled the strong password filter (for information on this see Q. How do I enable strong password filtering?) but your domain account policy has no password restrictions and allows blank passwords then you will get the error:

Your password must be at least 0 characters long. Your new password cannot be the same as any of your previous 0 passwords. Also, your site may require passwords that must be a combination of upper case, lower case, numbers, and non-alphanumeric characters. Type a password which meets these requirements in both text boxes.

To resolve this you will need to turn off the secure password filter

1. Start the registry editor (regedt32.exe)
2. Move to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa
3. Double click on "Notification Packages"
4. Remove the value "PASSFILT"
5. Click OK
6. Close the registry editor
7. Reboot the machine

Alternatively turn off the ability to have blank passwords:

1. Start User Manager
2. Select Account from the Policies menu
3. Set the minimum password length to 6 or above
4. Click OK
