Microsoft CA Certificate backup failed


C:\Backup>Certutil -p “xxxxxxxxxx” -f -backup “c:\backup”
CertUtil: -backup command FAILED: 0x8009000b (-2146893813)
CertUtil: Key not valid for use in specified state.


Check the Certificate of your CA whether the Private Key can be exported by starting an export of the Certificate. If the option “Yes , export the private key” is greyed out , this is possibly the problem. The picture shows how it should be.


Reimport the certificate from Backup with the option to allow Private Key export
