I have a win 2003 that fails the cpu util when using WMI.  I get the error "invalid use of null: 'cstr'" when I run the cpu.vbs command manually.  It works on other systems so it seems to be a issue with the system, but I'm not sure where it's at.  I saw a previous post where someone were having a problem with the disk.vbs which was fixed in the script.  Anyone know what causes this problem?  I'm using Opmanager 8.5 (8050).
