Event ID 4 — TPM Driver Operation
Updated: December 16, 2008
Applies To: Windows Server 2008 R2
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.

This is a normal condition. No further action is required.
