RIS Error 00004e44 - WePOS Image

Hi there. I'm trying to get a WePOS (Windows Embedded Point of Service)
RiPrep image to deploy via RIS. Unfortunately after I log into the Client
Installation Wizard and choose my RiPrep Image I get Error 00004e44 - which
leads me to KB262801 (http://support.microsoft.com/kb/262801). I do have
WePOS RiSetup image on the RIS box.

One of the bullet points in KB262801 mentions an NTOSKRNL.exe hotfix, which
we have applied since the WePOS 1.1 version does not ship with a version of
NTOSKRNL.exe (The step by step guide at
http://msdn.microsoft.com/en-us/library/ms911830.aspx says to install
http://support.microsoft.com/kb/814199 on page 2). I have tried to add the
new NTOSKRNL.exe to the existing RiSetup image to no avail.

Does anyone have any ideas how I can "trick" RIS/BINLSVC into seeing a valid
RiSetup image ?

Thanks, JC
