My application converts data from a BDE database into FB 2.0.1. It
works fine on my XP development system. But when it's run on my
partner's Vista machine, sometime in the middle of doing this
conversion it suddenly stops with this error:

ISC ERROR CODE:335544375

Unavailable database

Since I'm not in the same room with this system when it's being
tested, I don't know exactly where this occurs. The conversion
involves the creation of two distinct FDBs, so it might be when the
second is created (although a file access problem, ISTM, is reported
as isc_io_error, 335544344).

Can someone tell me what circumstances might cause isc_unavailable
to be reported?
