reinstalling iis

[sted]

ive been trying to get a php/sql rorum funning on iis7 win 2008 x64 and had made various changes to iis including one that crashed iis worker repeatedly. I decided as there was nowt much on there to get it back to default settings id remove it (and wsus) and then reinstall it. It uninstalled quite happily but will now after several attempts / reboots etc wont go back on again server manager basically says failed please reboot

ive put the log file i managed to get out but it dosent seem to tell me much other than it thinks somethings still installed

any ideas as i could do to get wsus reinstalled

right fixed it i uninstalled windows process activation rebooted and it reinstalled fine now just to rebuild wsus
