BitLocker - PXE-Boot with and without Network connected! RRS feed

  • Frage

  • Hi @ll,

    got a problem on Windows 7 Enterprise with bitlocker enabled System Drive. Installation and everythin works fin, but if i boot my Client wihtout Network connection, Bitlocker wont decrypt Drive and says " The system boot information has changed since Bitlocker was enabled". If i plugin my networkcable, an getting pxe bootinfox everithing works fine.
    I think the problem is caused by pxe bootorder.
    I have tried to change the "TPM plattform validation profile" PCR4, PCR8, PCR9 and PCR110 in GPO, suspendet bitlocker and reanabled but nothing works.

    Any hints?

    hardwaer its an HP 2510p --> have found a prob that mybe caused by the same situation!
