Resolution

This failure can be an indication network security properties are mismatched between the Source and Target Engines. A user with sysadmin privileges can log into the System Setup UI and review the Custom Authorizations settings to determine if client or server authorization for network test remote connections is configured on one Engine and not the other by comparing the values in the Network Security pane. Example:

In this instance, the failure indicates a misconfiguration between the two Engines (directionality of test does not matter in this instance). The Custom Authorization settings for "Perform Server authorization for network test remote connections" and/or "Perform Client authorization for network test remote connections" must be corrected in order for the test to be successful.
