Hi Anybody know anything about this error message i keep getting after setup has copied the files to the Hard drive. Big Blue screen, Problem caused by setupdd.sys stop : 0x000000BE (0xf99f3940, 0x01d3d121,0xf9597758,0x0000000b) setupdd.sys - address F99aa3c1 base at f999c000, Datestamp 3d6dd67f I have narrowed it down to slipstreaming the Rollup, it does not happen if i have just got SP1 included in the CD, could it be a Corrupt WindowsXP-KB826939-x86-ENU.exe. Thanks
