Certification Authority Support for Windows Mobile 5 and Earlier

Using Windows Server 2008 for Native Mode Mobile Device Management
The certification authority (CA) in Windows Server 2008 does not support Configuration Manager 2007 mobile device certificate enroller certificate requests from Windows Mobile 5 and earlier mobile devices. To enroll a certificate for Windows Mobile 5.0 and earlier mobile devices for native mode mobile device management by using the certificate enroller included in Configuration Manager 2007, the request should be sent to a Windows Server 2003 CA. Windows Mobile 6 and later device enrollment is supported by the Windows Server 2008 CA. For more information about configuring the CA for mobile device management, see "CertEnrollServer" in Mobile Device Client Configuration Values for the DMCommonInstaller.ini and ClientSettings.ini files located in <installation directory> / DeviceClientDeployment / ClientTransfer directory. For more information about certificate enroller support in Windows Server 2008, see article 922706 in the Microsoft Knowledge Base (http://go.microsoft.com/fwlink/?LinkID=110058).
