The Account Name is Invalid or Does Not Exist, or the Password is Invalid for the Account Name Specified

Purpose

PDQ Deploy and / or PDQ Inventory report The account name is invalid or does not exist or The password is invalid for the account name specified. 

Resolution

This is a native Windows service error that PDQ Deploy is relaying. This occurs when you use a domain account to run a Windows service and Windows is unable to validate the account with a Domain Controller. 

When you run a Scan or Deployment, there is a temporary Runner Service that is created on the target computer to run the Scan / Deployment process. This service is created using the PDQ Deploy User or the PDQ Inventory Scan User account.

How It Works: PDQ Deploy 

How It Works: PDQ Inventory 

The PowerShell command below can be ran on the target computer, to determine if it can communicate with a Domain Controller. 

Test-ComputerSecureChannel -Verbose

If the result is False, the target computer is unable to authenticate against a Domain Controller. 

The following are the most common causes for this error: 

• The target computer lost the trust relationship with the Domain.
• The netlogon service is not running on the target computer.
• Networking rules or policies preventing communication between the computer and DC. 

If you're using an Azure AD account it will fail since the account can't be validated against a Domain Controller. Microsoft doesn't support running Windows services as Azure AD accounts. You will have to use either a local or an on-prem AD account.
