Using Access 2000 with VB .Net

Hi
I am having a number of problems with a folder full of access databases
which are opened according to who has logged on in this system I am writing.
I have take the advice of the XP Pro group and ensured that I am identiried
as the owner of the relevant folder. I and the System have the 'full
control' we need.

I can create a new database as part of testing a logon and it perists as it
is updated and saved manually. These databases are completely unsecured
Access databases in the Access sense of 'secured'. All the security is
provided by the logic of the system I am writing

Then as soon as my system attempts to open the new database it disappears
and is reported by the logon not to exist. This phenomenon has only just
started to occur
Since the XP experts can not explain it, is it likely to be caused by
something in Access
