Connect to the Windows RDP Server
Launch Vinagre and click Connect or File → Connect from the top menu. In the connection window, select RDP if the option is available, then enter the IP address or hostname of your Windows RDP server.
Next, enter the credentials for the Windows account you want to use. For a standard local account, enter the username and password.

The default RDP port is 3389. If your Windows server uses a custom port, enter the corresponding port number instead.
If the Windows server uses a domain account, enter the username in a format such as DOMAIN\Username.
Then click Connect. Vinagre will attempt to establish the RDP session. If the connection is successful, the remote Windows desktop will appear in the Vinagre window.
