Data access IIS7/Vista/Acess2000

Hi

Have just installed IIS7 on Vista and am trying to access a .mdb file
through ASP. Getting server error.

I think the problem is in the file permission. Under XP Pro/IIS6 is used to
have to set the .mdb file security via windows explorer to give
IUSR_machinename full permissions on this file for anonymous web access.

Cant seem to do this with Vista explorer - says object cannot be found.

Also, getting conflicting statements from IIS Help - it tells me firstly
that

a. By default, IIS 7.0 uses IUSR as the account for anonymous access.
This account is created when you install IIS 7.0.

and then

b. Similarly, a new Windows built-in account named IUSRS replaces the
local IUSR_MachineName anonymous account from IIS 6.0.

Anyway, whatever syntax I use, I cant seem to add anonymous web user
permission to daters.mdb via the security tab in Windown Explorer.

Any help greatly appreciated - getting very frustrated

Thanks

Hugh
