[vbox-dev] "Failed to create a session" after building OSE 3.2.6 on WindowsXP SP3

[Feng, Haitao]

Hi,

I have followed your build instruction for Windows, but failed to create a new
virtual machine by using the built VirtualBox OSE.

My build env:

Windows XP SP3
VS2005 with service pack 1
Windows Platform SDK v6.1
Windows DDK 3900.1830

During building, there are some compilation errors. Those could be walked around 
by modifying the WINNT.h to remove the volatile keyword from _interlockedbittestandset, 
modifying some Makefile.kmk to change the _WIN32_WINNT to 0x0501. 

But after building, when I create a new VM, VirtualBox complains "Failed to create a session". 
Could you help me to solve this issue?

BTW: The OSE version works after I installed the PUEL 3.2.6, copied the VBoxSVC.exe, 
VBoxC.dll, VBoxDDU.dll and VBoxDD.dll to OSE version, and then uninstalled the PUEL 3.2.6.
So I suspect this issue is related to Platform SDK and DDK.

Thanks
