Get Information of Servers running on remote windows machine

Hi everyone,

I want to get the information of servers like IIS, Windows Apache server..etc. which are running on remote windows machine.
Further i want to know the .NET applications and web-services hosted on these servers.

I knew, there are some WMI classes; But dont know exactly which will be helpfull..
Please let me know, if there is anyother way to get this info..

Thank You in advance…
