Login Using MSTSC


This section describes how to use the remote login tool MSTSC to log in to a Windows ECS from a local computer.


  • The target ECS is running.

  • You have obtained the password for logging in to the Windows ECS. For details, see Obtaining the Password for Logging In to a Windows ECS.

  • You have bound an EIP to the ECS. For details, see Binding an EIP.

  • Access to port 3389 is allowed in the inbound direction of the security group to which the ECS belongs. For details, see Configuring Security Group Rules.

  • The network connection between the login tool and the target ECS is normal. For example, the default port 3389 is not blocked by the firewall.

  • Remote Desktop Protocol (RDP) needs to be enabled on the target ECS. For ECSs created using public images, RDP has been enabled by default. For instructions about how to enable RDP, see Enabling RDP.

  7. Click Connect and enter the login password as prompted to log in to the ECS.

    To ensure system security, change the login password after you log in to the ECS for the first time.

  8. (Optional) After logging in to the ECS using RDP, handle the issue that local files larger than 2 GB cannot be copied to a remote Windows ECS.

    For details, see troubleshooting cases.

Enabling RDP

For your first login, use VNC to log in and enable RDP for your ECS. Then, use MSTSC to log in.


By default, RDP has been enabled on the ECSs created using a public image.

  1. Log in to the Windows ECS using VNC.

    For details, see Login Using VNC.

  2. Click Start in the task bar and choose Control Panel > System and Security > System > Remote settings.

    The System Properties dialog box is displayed.
