Where do I get netdiag.exe and what is it?

A. Netdiag.exe is new to Windows 2000 but is not installed as part ofa core installation, instead it is part of the Windows 2000 support tools so toinstall perform the following:

A new program filessupport tools folder will be created and populated withthe utilities. It is adding to the path variable but any open cmd sessions willneed to be closed and restarted to load the new path environment string.

What does it do? Its similar to Network Monitor but not quite as good but runwith no options it will run tests on the adapters including domain membership,connection tests:

C:>netdiag
