Cause

This issue occurs due to a group policy object causing issues.

Resolution

  1. Do the UDL Test first to confirm the credentials have a connection to the SQL Server: Verify the SQL and Orion server connectivity using the UDL file
  2. If there are no issues with the connection, make sure to log in to the Orion server as a Local Admin Account to make sure that there are no other security policies being enforced that may cause the error in the process of installation / upgrade. Take note that Domain Admin accounts are still subject to Group Policy Objects.

Alternatively, switch from Windows Authentication to SQL Authentication as a workaround.
