The error message "Access Denied" typically indicates that the user attempting to connect does not have the necessary permissions to access the remote server. Here are some common causes and solutions for this issue:
- User Permissions: Ensure that the user account trying to connect belongs to a group that has the right to sign in remotely to the remote computer. You can check this through Group Policy or Local Security Policy settings.
- For Group Policy, navigate to Computer Configuration > Policies > Windows Settings > Security Settings > Local Policies > User Rights Assignment and verify that the user is part of a group listed under Allow logon through Remote Desktop Services.
- For Local Security Policy, access Local Security Policy on the remote computer and check the same settings.
- Account Restrictions: If you receive the message "Account restriction is preventing this user from signing in," it may be due to restrictions like Credential Guard that are preventing access.
- Remote Desktop Services Configuration: Ensure that the Remote Desktop Services are properly configured and that the user has the correct access rights to establish a connection.
- Firewall Settings: Check if the firewall settings on the remote computer are blocking the connection. Ensure that the Remote Desktop Protocol (RDP) is allowed through the firewall.
By verifying these settings and ensuring the user has the appropriate permissions, you should be able to resolve the "Access Denied" issue.
