Configuration: Windows Server 2008 Enterprise AD CS Root/intermediate, Domain Win 2008 R2, Windows 8.1 and Win 7 clients
When attempting to renew a email encryption certificate using the same key via the MMC in Windows 8.1, I receive the following:
An error occurred while enrolling for a certificate. A certificate request could not be created.
Error: The requested operation is not supported. 0x80090029 (-2146893783 NTE_NOT_SUPPORTED)
If I try to renew a certificate from Windows 7 or Windows Server 2008 it works OK.
What has changed with Windows 8.1 and certificates? Do I need to Migrate AD CS to 2012 R2 to support Win 8.x clients or is a good idea regardless? How may I resolve this issue?
Thanks,
Craig
