  2. SCEP certificates are stored incorrectly when no TPM is present on a Windows 8.1-based device

SCEP certificates are stored incorrectly when no TPM is present on a Windows 8.1-based device

View products that this article applies to.

Symptoms

Consider the following scenario:
  • You deploy certificates to be used for client authentications on network services such as VPN and Wi-Fi. 
  • You provision a Simple Certificate Enrollment Protocol (SCEP) profile on a Windows 8.1-based device.
  • You set to store certificates only with a trusted platform module (TPM) key storage provider (KSP) by using the SCEP profile.
In this scenario, the certificate enrollment should only proceed if a TPM is present on the device. However, when there is no TPM present, the certificate is still successfully enrolled, and the certificates that are provisioned to the device are stored in the KSP unexpectedly.
