Hi,

We develop a server-side application which receives incoming https connections using self-signed certificate. It was all ok while we were using Windows 7 or Windows 2008 as OS, but when our clients started installing Windows 8 as server OS they encountered big problem: application got unavailable in few hours after start. 

In event logs we have following:

A fatal error occurred when attempting to access the SSL server credential private key. The error code returned from the cryptographic module is 0x8009030d. The internal error state is 10001.

After restart, application recreates certificate and all works normal few hours till next fatal error.

This article did not help us. And I repeat that this error appears only on Windows 8 (we tested on Windows 8.1). Windows 2012 Server we did not test yet.

How we can solve this problem?

Best regards.

Hi,

The error indicates that SSL server does not have a private Key on it.

I suspect the issue was caused by the certificate.

Since this application is developed by you,I suggest you check your certificate to see if the certicate support Windows 8.

Hi,

What is the difference between windows 7 and windows 8 in case of certificates? How to check, that certificate supports windows 8? To create certificate we used code attached code from this article:

Thanks!

Hi,

Since this article released in 2008,I suspect the code mentioned in this article doesn't  supprot Windows 8.

And since the certificate was written by C#,I suggest you submit a new case on MSDN Forum as they will be more professional on your issue:
