The FileSystem Object runs as the Web Service account (normally 
"IUSR_<MachineName>"). If that account has read access, then doing a 
FileExists should be kosher. Obviously, unless that account has more 
permissions than that (read/write/modify or full control) for the target 
directory, the web account will not be able to write to that directory.

The biggest gotcha I always see is people not allowing read/write/modify on 
the directory AND an Access file. Normally they only have it on the Access 
file. Since Access requires a lock file, you need to have more permissions 
on the directory itself where the Access file resides to create the lock file.
