Starting with Windows Vista, Windows Server 2008, Remote Desktop Protocol (sqlremote Desktop Protocol, RDP) supports Network Level authentication (network levels authentication Referred to as NLA). By enabling NLA, our RDP will be more robust, and the client will no longer be able to display the login interface of the remote system before the RDP login, and will be successful and log on directly to the system desktop after the client has the correct logon authentication.
In this way, in addition to avoid some of the information leakage, but also effectively prevent the remote client malicious exhaustive. As shown in the following illustration, we only need to enable "only allow computer connections with Remote Desktop with network Level Authentication" in remote settings.
Once NLA is enabled on the server-side RDP service and the client is Windows Vista or above, we can log on directly via remote Desktop, otherwise, as shown in the following illustration, even if the latest version of Remote Desktop is installed Windo Remote Desktop access on the WS XP SP3 still prompts for errors. (PS: Do not panic and busy notify the relevant personnel to disable NLA locally.) )
