Andrea,

ASP requests get forwared to an DLLHOST process if you configure the
site/vdir to run in medium or high isolation. This DLLHost process runs as
the IWAM account which is a simple user account with not a lot of rights.
If you run in high isolation ASP requests get executed withing INETINFO.EXE,
which is the core IIS process. INETINFO.EXE runs as LocalSystem and is
basically god on the machine. It's a good security practice to run in medium
or high isolation.

Your error seems to be caused by multiple processes trying to access the
same Access database. There are two articles on Microsoft.com that talk
about the problem:

http://support.microsoft.com/default.aspx?scid=KB;EN-US;Q306269&
http://support.microsoft.com/default.aspx?scid=KB;EN-US;Q306518&

Hope this helps.
