I'm trying to run an application under another user within a winform
app writen in C#.  I have tried a number of different things, but it
seems that the CreateProcessWithLogonW function should work to do what
I need to do.  This appears to work just fine in Windows 2000 and XP
with service pack 1, but it doesn't work with XP service pack 2
installed.

I'm sure it's one of the "Enhanced security features" of service pack
2, but I can't seem to get this to work.  The function returns a 1
indicating that it worked fine, but the applcation that I'm trying
launch does not launch.

To give a little background on what I'm doing:

I have written a small app that is basically just an interface for the
netsh command to change network setting for the user.  The users do not

have admin rights on their machines, but a select few need to be able
to change their IP addresses for buisness reasons.  Because of this, I
basically just call the CreateProcessWithLogonW function to start run
the netsh command under an admin account on the machine to change the
IP address to whatever the user specifies in the interface that I
provided.

As a test, I have created two very simple windows apps.  The first one
calls the CreateProcessWithLogonW function to login as another account
on the machine.  It then calls another simple application that uses the

WindowsIdentity to show the current user.  This works fine on Win2K and

XP sp1, but not with service pack 2.

If anyone know how to get around this, that would be great.

Thanks,
Jerry
