Remote Desktop Software for Windows Mobile 6.5

Windows Mobile 6.5 featured a native remote administration tool called Remote Desktop Mobile, which allowed users to connect remotely to Windows desktop computers and servers using Microsoft's proprietary Remote Desktop Protocol (RDP). This article covers the features, functionality, system capabilities, and practical limitations of Remote Desktop Mobile during the Windows Mobile era.

The Native Client: Remote Desktop Mobile

The built-in application on Windows Mobile 6.5 was officially titled Remote Desktop Mobile (often referenced internally by its executable name, wpctsc.exe). It was the mobile iteration of the desktop Remote Desktop Connection client (mstsc.exe), developed by Microsoft to bring Terminal Services and RDP access to handheld PDAs and smartphones.

Although its inclusion occasionally depended on the specific device manufacturer (OEM) or carrier ROM customization, Remote Desktop Mobile was the official, Microsoft-supplied native solution packaged with the Windows Mobile 6.5 operating system.

Key Features and Functionality

Remote Desktop Mobile provided essential desktop control capabilities adapted for handheld hardware:

  • Remote Desktop Protocol (RDP) Support: The client utilized RDP 5.x and 6.x protocols, enabling secure connections over local Wi-Fi networks as well as cellular data connections (GPRS, EDGE, 3G).
  • Display and Resolution Modes: Because desktop resolutions far exceeded typical Windows Mobile screen resolutions (such as QVGA at 320x240 or WVGA at 800x480), the client offered two viewing modes:
    • Fit to Screen: Scaled down the remote display to prevent horizontal and vertical scrolling.
    • Full Screen (Actual Size): Displayed the host desktop at native resolution, allowing the user to pan around the screen using directional keys or touch.
  • Touch and Stylus Input: Users could interact with the remote operating system using a stylus or capacitive touch depending on the device, translating screen taps directly into mouse clicks.
  • Audio Redirection: The client supported redirecting sound from the host PC so it would play locally through the mobile device’s speakers or headphones.

Host Compatibility

To establish a session using Remote Desktop Mobile, the target host machine had to run an edition of Windows that supported incoming RDP connections. Supported operating systems included:

  • Windows XP Professional
  • Windows Vista Business, Enterprise, and Ultimate
  • Windows 7 Professional, Enterprise, and Ultimate
  • Windows Server 2000, 2003, 2008, and 2008 R2

Home editions of consumer Windows operating systems did not support hosting RDP sessions and could not be accessed natively without third-party modifications or tools.

Accessing the Application

On standard Windows Mobile 6.5 devices, the application was located by navigating to the Start Menu and opening the Office Mobile folder or the general Programs list. Connecting required entering the IP address or host name of the target machine, along with valid user credentials (username, password, and domain if applicable) configured on the host machine.
