Error 0x8007045D: Failed to connect some files in Windows Server 2008 Installation

Hi Experts,
I wanted complete installation of Windows Server 2008. Previously I had Windows Server 2003 64 bit and it worked fine. During installing Windows Server 2008 has encountered a problem. It has failed to connect some files and shown the error code 0x8007045D.
Have you any idea for the error code? Please help me to get a remedy of this problem.
Thanks.
