Scanning Network in C#

I got problem in scanning other computer which is connected through network in order to display its specification.

I have tried using WMI and succeeded to perform all the operation to display IP, Comp name, Domain name, etc on my own computer (single computer)

now what my aim is to display each computer specification on the same domain or network? (different computer not only my computer)

It is something looks like network neighbourhood in windows. but the difference is if i click the icon computer it will display the specification of the computer instead of the shared folder.

PLease help me!

Thanks
