Windows CE devices, including Skorpio X4 WEC7, may encounter errors when attempting to connect to Windows Server 2012 or 2016 via Remote Desktop Protocol (RDP). These errors are typically due to security protocol mismatches between the legacy RDP client on CE and the newer server configurations.
Cause
- The RDP client on Windows CE is a Microsoft-integrated component and has limited support for modern encryption and authentication protocols.
- Windows Server 2012/2016 enforces higher security standards by default, which may block connections from older clients.
Resolution
To allow connections from Windows CE devices:
1. Adjust Server Security Settings
Apply the following changes on the Windows Server:
Disable Network Level Authentication (NLA):
- Go to System Properties > Remote Settings
- Uncheck “Allow connections only from computers running Remote Desktop with Network Level Authentication”
Modify Group Policy Settings:
- Open Group Policy Editor (gpedit.msc)
- Navigate to:
- Computer Configuration > Administrative Templates > Windows Components > Remote Desktop Services > Remote Desktop Session Host > Security
- Set the following:
- Require use of specific security layer for remote (RDP) connections: Set to RDP
- Require user authentication for remote connections by using NLA: Set to Disabled
- Restart the server or run gpupdate /force to apply changes.

Additional Notes
These changes reduce server-side security to accommodate legacy clients. Use caution in production environments.
Consider upgrading to newer devices or RDP clients that support modern protocols for long-term compatibility.
