I think you have a network problem of some kind. Could you try to hook 
up one thin client to the thin client server directly using a crossover 
TP cable and see if that helps?

Alternatively try running with out that script you mention.

There is no generic problem with the thin client solution that we are 
aware of, so I am inclined to ask you to look at your own setup again. 
Those symlinks in /opt/ltsp look very suspicious. They are not supposed 
to be there. Further down in the /opt/ltsp/i386 tree there are a number 
of symlinks that look as if they are dangling. That is normal, they are 
hooks for the thin clients and only give meaning inside a thin client 
mounted root file system.
