User name is unknown or invalid

Description

The provided user name either does not exist or is not valid for the target system.

Possible Causes

The most common cause is using a local administrator user account name that doesn't exist on the target computer. Can also be caused by a typo or special character in the name.

Recommended Fix

Ensure that the user name is correct and that the account exists on the target device and try again.
