Situation: one of outside client cant login remote Desktop server with this error: Your credentials did not work. Your system administrator doesn’t allow the use of saved the credentials to log on to the remote Computer.
Troubleshooting: 1. Use other computer with the same username doesn’t have this problem.
2. We fixes it by do this:
“The reason why it wasn’t working was because Windows automatically stored the certificate in a “non-trusted” root store. Once it was moved RDP connected without prompting for credentials”
Other suggestions: 1. Change the group policy setting.
2. Security settings.
3. If the client is located the same LAN, change the network profile from public to private.
4. Make sure the company firewall allow remote session.
5. Edit Windows Security Policy.
6. Delete the credentials:
Go to Control Panel -> Credential Manager. You will see three sections:
- Windows Credentials
- Certificate-Based Credentials
- Generic Credentials
Remove the credentials from Windows Credentials and add it to Generic Credentials.
