Hello,
The error code 0x516 usually indicates that there is a problem with the authentication process. This error can occur if the credentials you are using to connect to the other computer are incorrect or if there is a problem with the network connection.
To resolve this issue,
Check that the network connection is working correctly. You can try pinging the other computer to see if it responds.
