Jiann-Ming;

I think the short answer to your question is yes.  The NDT server sends 
the test results, including the web100 data back to the client after the 
test completes.

One thing you can do is to look at the Java console log on your failing 
clients.  That might give you some insight.  Also if you are running 
your own server, then the server log 'web100srv.log' can give you some 
details as well.

As I noted below, there are some bugs in the NDT 3.5 & 3.6 code train. 
The 3.4.4a code is very stable, especially if you want to run in single 
user mode with FIFO queuing.

Regards;
Rich
