Task Sequence Failure to find the boot Image (0x80040103)

Task sequence on our secondary site is failing.

Our site is SCCM 2007 SP2 and we are trying to deploy Windows 7 x64

As seen the task sequence fails on fetching the boot image

the smsts log shows the following

I have already refreshed the package 

I updated DP

Tried re-entering Network Access account 

Tried re adding the Boot image to the Task Sequence 

Created new task sequence

The Task sequence in the primary site works fine.

We checked and found the Machine does get IP address , and is able to ping and resolve the DP.
