Hi, I am trying to use RIS (on 2003 Server) to load Win PE and then use Powerquest tools to deploy an image. This all works fine apart from on Compaq Evo ( ) D510 machines - the RIS component will load but soon after trying to start PE I receive the error: File e100bnt5.sys caused an unexpected error (21) at line 3752 in D:\XPSP1\base\boot\setup\setup.c Initially there were problems getting even RIS to work on this PC type due to the NIC (Intel Pro VM 100) but I have resolved this and RIS on its own is fine Any help will be greatly appreciated! Many thanks!!
