Hi Sachin.
I am unable to find where this sbslpog_pxe is located. I have looked in this path, but do not see that file:
D:\Program Files\Altiris\Altiris Agent\Agents\Deployment\Task Handler\SBS
As for the Boot to Production tasks, it works just fine. Since my boot order is NIC, and then Hard Drive, it exits the boot agent and continues to boot into Windows. Boot to Production produces a task of: 100% Succeeded.
Now, if I run the Boot to PXE task, it does the same thing, boots to NIC, says "Altiris", acts like it is going there, and then "Exiting Intel Boot Agent". The console will then report that the Boot to PXE task was 100% successful, although I can physically look and see that the PC is booted into Windows.
