Getting error 515 installing SMS on client computers running windows XP SP1. All clients show in collection. WMI is corrupt on all machines which explains why SMS was not installed on machines upon discovery. After repairing WMI, i run ccmsetup.exe and it runs through without errors but will not fully install. Processes show ccmsetup running but it will run for hours without doing anything. I tried pushing, installing from network share and copying locally and nothing seems to work. Anyone have any ideas??
