Yeah, that solved the issue, a test result appear now at the end, thanks :-).

Why would the server try to connect back to my client machine? whats the 
crossplatform.xml?? this file do not exist at all on the server!!

2) The test result attached has:
   The last 2 lines indicates a bug I guess!! could the "%2F" in line 
"network: Connecting http://%2F10.0.0.70/crossdomain.xml with proxy=DIRECT" 
in comment 1 above mean the same thing??

Thanks for your support,
Adel M. Riyad

Hey Adel,

Could you try using the source tarball from 
http://ndb1.internet2.edu/~aaron/ndt-3.6.5.2-rc2.i386/ndt-3.6.5.2.tar.gz and 
see if it fixes the issue you're seeing?

Cheers,
Aaron
