What to enter in the client
Use the first IPv4 address as the connection address. Get the login account and password from the relevant server details rather than guessing the default account based on the operating system version. If the client has saved credentials, first confirm that they belong to the server just provisioned.
If a Remote Desktop identity or certificate prompt appears, check the connection target and address. Do not rely on a saved connection name alone to identify the target, or treat a certificate prompt as a password error.
