What Do I Do If I Cannot Log In to a Windows BMS?

Troubleshoot

If you cannot connect to a BMS using the remote desktop, do as follows:

1. Check Whether Login Conditions Are Met
2. Check Network Connectivity
3. Check Whether the Firewall Is Correctly Configured
4. Check the Port for Remotely Accessing the BMS
5. Restart the BMS

Check Whether Login Conditions Are Met

Check whether the login is properly prepared. For details, see What Need to Be Prepared for Logging In to a BMS?.

Check Network Connectivity

Check whether the EIP bound to the BMS can be pinged. If the EIP cannot be pinged, check whether the following rule has been added to the security group. If it is not, add it.

Then, try to remotely log in to the BMS again.

Check Whether the Firewall Is Correctly Configured

The firewall of the BMS must allow the remote connection port (3389 by default). If you have not configured the remote connection port in the inbound rule, you cannot remotely log in to the BMS. In this case, add the remote connection port to the inbound rule of the firewall. For details, see Adding a Port Exception on a Windows ECS Firewall.

Then, try to remotely log in to the BMS again.

Check the Port for Remotely Accessing the BMS

Check whether port 3389 of the BMS can be accessed.

If the port is inaccessible, check whether this port is allowed by the security group. If it is not, add a security group rule to allow it.

• Default Security Groups and Security Group Rules
• Adding Security Group Rules

Then, try to remotely log in to the BMS again.

Restart the BMS

If the preceding configurations are correct, and you still cannot log in, restart the BMS on the console. The restart operation will stop the server and interrupt services. Exercise caution when performing this operation.

Then, try to remotely log in to the BMS again.
