Logging In to Windows Instance Using RDP

Last updated: 2022-05-18 14:38:26
    Note:

    WebRDP is the default login method for Windows instances. It allows you to log in to a Windows instance in the CVM console without downloading a local login client.

    Overview

    Remote Desktop Protocol (RDP) is a multiple-channel protocol developed by Microsoft that allows a local computer to connect to a remote computer. We recommend you use RDP to log in to your Windows CVMs. This document describes how to log in to Windows instances using RDP files.

    Supported Systems

    You can log in to your CVMs from Windows, Linux, and MacOS servers using RDP.

    Prerequisites

    • You must have the admin account and password for logging in to a Windows instance remotely.
    • If you have chosen to generate a random password when creating an instance, please get it from Message Center.
    • If you have set a login password, please use it for login. If you forgot it, please reset it.
    • You have purchased a public IP for your CVM instance and opened a remote login port (3389 by default) for the WebRDP proxy IP in the security group associated with the instance.
    • If you purchase a CVM instance through quick configuration, the port is opened by default.
    • If you purchase a CVM instance through custom configuration, you can manually open the port as instructed in Security Group Use Cases.
    • Make sure that the public network bandwidth of your instance is ≥ 5 Mbit/s; otherwise, the remote desktop may lag. To adjust the network bandwidth, please see Adjusting Network Configuration.

    Directions

    1. Log in to the CVM console.
    2. On the Instances page, locate the Windows CVM instance you want to log in to and click Log In.
    3. In the Standard Login | Windows Instance window that is opened, select Download RDP File.
      >?If you have changed the remote login port, append the IP address with :port in the RDP file.
      >
    4. Double-Click the downloaded RDP file, enter the password, and click OK to remotely connect to your Windows CVM.

    RDP Bandwidth Limit Description

    The available network bandwidth directly affects the experience of logging in to and using CVM instances over RDP, and different applications and display resolutions require different network configurations. Microsoft has laid down the minimum bandwidth requirements for instances when using RDP in different application scenarios. Please check out the following table to make sure that the network configuration of your instance can meet your business needs; otherwise, issues such as lag may occur.

    Note:

    To adjust the bandwidth of your instance, please see Adjusting Network Configuration.
