How to install root certificates

Only trusted processes can install certificates. On a two-tier device, only privileged applications can run trusted processes. Therefore, the device manager (the OEM or the mobile operator) must let you install a certificate. Alternatively, the device manager must sign the application with a certificate that is in the privileged execution certificate store on the device.

When you are granted a device manager role on a Windows Mobile-based device, you can install a root certificate file by using the built-in certificate installer. To use the built-in certificate installer, follow these steps: http://support.microsoft.com/kb/915840

1. Connect the mobile device to the computer.
2. On the computer, start ActiveSync 4.1, and then click Explore.
3. Copy the root certificate file (.cer) to the device.
4. On the device, run the .cer file that is associated with the built-in Certinst.exe file.

If the security policy on the Windows Mobile-based device prevents the built-in certificate installer from working, try the following steps to install the certificate:

1. Download the SmartPhoneAddcert.exe tool to your computer. The following file is available for download from the Microsoft Download Center:

   Note Some mobile operators provide a signed version of this tool. If a signed version is available for your device, download the signed version.
2. Run SmartPhoneAddCert.exe to extract the contents to a folder on your computer.
3. Copy SmartPhoneAddCert.exe to your device.
4. On your device, create a folder that is named "Storage." SmartPhonePAddCert.exe searches for the certificate in this folder.
5. Copy the root certificate (.cer file) to the Storage folder on your device.
6. Run SmartPhoneAddCert.exe. Click to select the .cer file that you copied to the Storage folder, and then install the root certificate.

  After than, that's great! I can logon my working station through my mobile phone! Amazing!
