UPDATE NOTICE
Please use the new Data Port Server 1.52 Installer for Windows Mobile 5 Pocket PC to install the RemSqlCe.dll file on Windows Mobile 5 Pocket PC devices. The information below should be considered obsolete.

When using any of the remote data access product on a Windows Mobile 5 device, you may experience connectivity problems. This is due to the fact that, by default, the Windows Mobile 5 security policy prevents any remote access to the device via RAPI calls.

Primeworks remote data access products rely on a working RAPI or TCP/IP connection to the remote device. If this connection is missing, they fail to work as expected.

To work around this problem, here are two alternative approaches:

• Create a provisioning script for RemSqlCe.dll. Please read this MSDN article to learn how.
• Set the device's registry key HKLM\Security\Policies\Policies\00001001 to 1 (DWORD). This will effectively enable all remote RAPI calls to the device (read more here).
• You can also download the EnableRAPI tool. Copy the exe file to the Windows Mobile 5 device using ActiveSync and execute it. After the usual "Unknown publisher" warning, click Yes on the message box.
