While working on one of my Windows 2008 R2 servers, I noticed the following error in the event log over and over:
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.
I’m running SQL Server 2008 R2 on this machine and didn’t think it had anything to do with the error, but I was wrong. Turns out that the service account running SQL Server needs security access to: C:\ProgramData\Microsoft\Crypto\RSA\MachineKeys.
The Fix:
1. Open windows explorer and navigate to: C:\ProgramData\Microsoft\Crypto\RSA\
2. Right click on the folder MachineKeys
3. Set the security to add full control to whatever service is running SQL Server.
I’ve checked a few other machines with this error and this fix resolved the problem.
