Explanation
Domain credentials are authenticated by a domain controller, which requires the computer to be a member of the domain. If the laptop was never joined to the domain, it cannot communicate with the domain controller to validate Joe's network credentials. The coworker's PC is domain-joined and authenticates successfully. A disabled administrator account, FAT32 formatting, or missing input drivers would not cause this specific pattern of credential failure on one machine but not another.
