I am researching the issue for you, but I believe those ar the only 2 ways. I am trying to confirm this though. What are you needing the device PPIDs for, is there an issue with the server currently?
Let me know
It doesn't look like there is. What is the device you're trying to get the information for. I believe the internal server devices will assume the PPID of the server itself. Could you clarify if there is an issue with the server itself?
