Thank you Pual for the response. The Process is not a system process and up
to now I checked all priviledges and they seemed ok.
However, I think I found something new about the process I'm trying to call
OpenProcess on. The process seems to have its Access Control Entry set to
deny \Everyone. Just this one process. How would you set this? How could
you remove this? I found this out using Microsoft's Standard User Analyzer.
It reported this Warning mesage on the process: 'Deny Access Control Entry
(ACE) Encountered. Open Porcess: pid (process id #) denies
'PROCESS_VM_READ' to \Everyone'.
Can anyone help with this?
