Dear group,

I'm getting a strange problem in ASP/IIS/Jet (not exactly sure which of
these is responsible)

We have a customer inquiry tracking system (pretty much the typical one),
and we are making a web interface for the customers to be able to see their
inquiries.

The system has its database in Access, and uses DAO for accessing it (i
know, i know, but we are not planning to rewrite the code yet).
The ASP pages don't access the database directly. They call methods in
classes in an ActiveX DLL, which return the corresponding data. The DLL
opens the database connection the first time one of its methods is called,
and the connection stays open from then on.

This all works perfectly. However, we have a very strange problem.
Every once in a while, when someone tries to log on to the system (it's
usually the first one in that day, or when i try to log on during the
weekend), the first call to a method in the DLL that tries to access the
database gives the following error:

---------------------------------------------------------
DAO.Database (0x800A0C06)
The Microsoft Jet database engine cannot find the input table or query
'Contactos'. Make sure it exists and that its name is spelled correctly.
---------------------------------------------------------

This gets fixed as soon as we restart IIS.
I assume this has to do with the fact that the system (or the DB connection)
is not being used for a long time, and something breaks down. But the
strange thing is that this doesn't happen Always, it's only every once in a
while...

Has anyone experienced this kind of problems before?
Any ideas on what could be happening?

Thanks in advance
