Connect to the network
Applies To: Windows Server 2008
You cannot complete the initialization of the TPM in your computer if both of the following two conditions exist:
An administrator has configured your computer to require that TPM recovery information be saved in Active Directory Domain Services. This requirement can be configured through Group Policy.
A domain controller cannot be reached. This could occur on a computer that is not currently connected to the network, or is separated from the domain by a firewall, or because of a network component failure (such as an unplugged cable or a faulty network interface card).
In this case, an error appears, and you will not be able to complete the initialization process.
To avoid this issue, initialize the TPM while connected to the corporate network and able to contact a domain controller.
