Cause There is no single cause when receiving this error; it illustrates when something is blocking Powershell execution on the target machine.

Resolution When troubleshooting this error message, different fixes may work for different devices. The following may be useful steps to take to resolve this error:

Verify that the MID Server and target devices have a compatible version of Powershell installed. Set the Powershell execution policy to unrestricted in the target device. Verify that no firewall/security policies are blocking this connection from being established. Ensure that PSRemoting is enabled on the target device (steps available in KB0813330 - How to Enable/Test PowerShell Remoting on Windows Host ) Set all hosts to trusted hosts for PSRemoting on the target device (steps available in KB0813330 - How to Enable/Test PowerShell Remoting on Windows Host ) flushdns and registerdns on the target device Check for temp profiles of login being created on the target device which could block Discovery. Through the registry you can delete the temp profile & restart the user profile services service.
