VDA shows up as unregistered in the Studio console.

Error: "The trust relationship between this workstation and the primary domain failed"

To troubleshoot this issue:

• ​Verify the VDA is part of the domain. You can find this information in the VDA's System Properties or in the DNS console of the domain controller.
• Check the VDA's DNS and network settings to verify you can reach the domain controller from the VDA.
• Check the trust relationship between the VDA and the domain controller by running "Test-ComputerSecureChannel" cmdlet within an Admin Powershell window
• If the test returns False, you can determine the best correction method for your environment, such as manually rejoining the VDA to the domain or resetting the machine password.

Problem Cause

This issue can occur if:

• The VDA did not join the domain correctly.
• The trust relationship between the VDA and the domain controller failed.
• DNS name resolution might not be working.
• The domain controller can't be reached.
