The DTM that shipped in the Windows Vista RTM timeframe contains two versions of the NDISTest tool, v.6.0 and v.6.5. You can run both of these tools manually outside the DTM. Running the tools manually gives you flexibility in selecting which tests to run individually.
Here is how to do it:
The way to do this is to install the DTM controller on a PC and look for the following folder (driver letter might be different on your PC):
E:\Program Files\Microsoft Driver Test Manager\Tests\x86fre\nttest\NetTest\ndis
In this folder there will be 3 directories, two of which are:
Ndistest (6.0 version)
Ndistest.net (6.5 version)
Copy the tools to the machine on which you want to run the tests and just launch them.
You cannot go into "manual" mode in the DTM like you used to in the HCT so this is the only way to launch individual NDISTest tests.
