The main branch of the NDT from SourceForge's CVS is incompatible with
the publicly available servers. You should use the Java applet at
http://miranda.ctd.anl.gov:7123/

> Is there a better version of NDT that I should be using?

You can try the newest development version from the mdndt branch:

cvs 
-d:pserver::/cvsroot/ndt
 login
cvs -z3 
-d:pserver::/cvsroot/ndt
 co \
-r mdndt ndt

The publicly available server is located at web100.internet2.edu. You
can also access it by the http interface:
http://web100.internet2.edu:7123/

This is a known bug, which has already been fixed in the mdndt branch.
It appeared on a highly congested slow links.

> Thanks in advance for your help.

I will be grateful for any comments/ideas/suggestions about NDT.
