unattended PXE install

Hey,

Looking to remotely install the current version of pxe via script.  In the past we used pxe.exe and an setup.iss with a command line of somthing like this:

pxe.exe -s -f1c:\altiris\setup.iss -f2C:\altiris\test.log

Doesn't seem to work with the current package, still works ok if we use the old ds6.9 package and let things update but am hoping to update the process.  I can't seem to manually run pxe.exe either and pretty sure I used to.

Thanks
