SCCM 2007 R2 OSD Error

I am trying to do a simple OSD via PXE through SCCM 07R2.  I am using Vista Ent SP1 and the boot image that it SCCM comes with.  I am able to load the task sequence through PXE and it gets to the Applying Operating System And ConfigMgr Client section and then gives the client the following error:

Task Sequence:  %TaskName% has failed with the error code (0x80004005).  For more information, please contact your system administrator or helpdesk operator.

On the server side, the log has these three errors:

Error 1:

I am not sure what the problem is.  All of the folders that have the needed files are shared with "Everyone" and it seems the network interface is configured properly in WinPE.  Experts, please help!
