Hi there, I'm doing a program to detect LAN devices - including PC, routers, hubs, printers etc. I'm supposed to display all these devices in a treeview, and when I click on the name of the device, it shall then display the necessary info. Please provide any relevant info. Urgent help is needed. Thanks in advance.

Wow... OK... where to start....

WMI will be useful in getting PC-related information (RAM, hard drive, shares, etc).

But WMI will not do anything for you with regard to routers, hubs, etc.  Detecting network infastructure is a bit more complex.  Things would be a lot easier if each infastructure device had SNMP drivers, HP Openview, etc

Enumerating windows domain devices require API calls, there is no .Net framework way to do it.

I've got a program (written in VB.Net) that does a lot of WMI work (to include a section on enumerating devices).  You might find it usefull as an example.  ftp://ftp.dpw.hood.army.mil/programs/sosos

Have you been able to make any progress with the router/hub detection?

Nope... and remote system detection is getting harder and harder to do now, due to security concerns.   There used to be a common method of collect respones to IP probing (called signatures), but the concern over security has just about eliminated all of those methods.

The only thing left is to use Simple Network Management Protocol (SNMP) to hunt for active responses... but even that won't work in a "hardend" environment.

Sorry
