PXE Boot

Hi,

When i network boot the client machine to contact the WDS and boot the
winpe image, i get the Boot agent detail in the client as:
downloaded WDSNBP....
Architecture: X64
and
contacting server: ......................
I have configured the WDS to "respond to all........" and "for
unknown client, notify ........." and i think i have to approve this client
from the WDS. correct?

I have following questions:
1. why does it show as "Architecture: X64" in the "pending devices" section
of WDS even though the client is a x86 architecture?
2. Do i need to be a member of the domain admin group to approve the client
in the WDS? or even to make changes in the WDS properties?( right not i am
just a member of the domain and a member of the local admin group of the WDS).
Any tips for the above two issues? Quick response appreciated.

Thanks & regards,
AKR.
