Maury,
This is an Access function, no ?
How are you calling it ?

However, the "The Remote Machine is not accessible" error sounds like a
networking problem, albeit intermittent.

I have a large code library in an XLA that is stored on a network share.
Many
of the functions inside make use of the "NZ" function. Periodically, about
once a week, calls to NZ returns "The Remote Machine is not accessable",
and
the scripts fail. None of the other hundreds of calls fail.

Has anyone seen this behavior before? Any suggestions on how to avoid it?
It's a long-running process (15 minutes) so when this happens everything
has
to be re-started. Adding to the frustration, the dialog indicating a
problem
appears _behind_ the application and does not cause the taskbar icon to
flash, so it's all too common to simply miss this problem.
