Event ID 4 — TPM Driver Operation

  • Article

Applies To: Windows Server 2008

This version of Windows includes a device driver that allows the TPM Base Service (TBS) to communicate with and share the use of a Trusted Platform Module chip in the computer. Any failures in communication with the TPM or unexpected results cause the TPM driver or the TBS to log event messages.

Note: The BitLocker Drive Encryption feature uses the TPM by default.
