Overview
You sometimes notice that the Managed computer inventory task runs successfully without any exceptions and errors. However, the total count of computer in Managed computer inventory view do not match the individual totals for all the computers in different patch manager Computer groups.
For example, suppose you have Patch manager computer groups call PMCG_Clients and PMCG_Servers with each containing 6 computers.
However when you run the Managed Computer inventory for PMCG_Clients and PMCG_Servers, the total count is showing 10 instead of 12
And you have verified each group views i.e PMCG_Clients and PMCG_Servers, the total should be 12. The problem is causing by incorrect canonical path for the missing computers.
