Certificate enrolment error 0x80094800 on Win CE 5.0 device.

Question

 I want to enrol the certificate from Win CE 5.0 based device. Device (emulator) is connected to MS server 2008 and IIS 7.0, CA and active directory setup already done on server. I have found the enrol sample code from pocket pc SDK and while running the application it is prompting following error.

 Denied by Policy Module 0x80094800, the request was for a certificate template that is not supported by the Certificate Services Policy: ClientAuth

 While searching on net.It seems there is some issue with respect to certificate format used on AD. I am new to cryptography field. How to resolve this issue.

 Just for information, device has all priviledges to create and submit the certificate request and WinInet API's are also working fine.
