TBS Operation

Applies To: Windows Server 2008

This version of Windows includes TPM Base Services (TBS), a component similar to an Application Programming Interface (API) , that allows the operating system and application programs to communicate with and share the use of a Trusted Platform Module chip in the computer. The BitLocker Drive Encryption feature uses the TPM by default. Failures or unexpected results encountered by the TBS can result in the TBS or the TPM driver logging event messages.
