The program uses WMI (Windows Management Instrumentation) technology for accessing remote computers and collecting inventory data.
Pros of working with WMI:
- Does not require configuring remote computers in the majority of cases (when a domain and the administrative rights are available).
- No need to install additional components on remote computers.
- Users with no administrative rights cannot prevent the gathering of information.
- The polling is invisible for network users.
- Actual information can be obtained at any moment on demand.
Cons:
- Requires the administrative rights on remote computers.
- May require the adjustment of security policies and firewalls on computers (see WMI troubleshooting).
- Hard to poll computers that run rarely.
When computers cannot be accessed with WMI, the polling can be organized using a client (even from computers that are not connected to the network) and the agent service (when the administrative rights are unavailable).
