Does this work correctly if the server is an NT box?

Clipper goes way back.  It was, if I recall correctly, a compiler for dBase
programs.  Now, it's been about 15 years since I last used dBase.  I believe,
however, that they used a cooperative locking scheme.  That is, if process 1
set a lock, process 2 had to check the lock before using the data or corruption
would result.

I would assume that, in the years since I worked with these products, they've
implemented real locking.  It's just a thought...
