I have had the same problem. The first time I loaded a page it worked well, but if I loaded the page again quickly, then I got this error. If I waited for a while then I didn't get the error. It must be because when you call objConnection.Close it takes some time to actually close the mdb file, so if you try and open it again you get the "File already in use type error". Strangely adding a mode to the connection sorted this problem out for me. It doesn't have to be read only, read / write works as well.

objConnection.Mode = 1 ' read only

Whatever happened, it is resulting in an 80004005 error, so the problem is definitely a permission issue.

Depending on the configuration of the web server, it may not be the IUSR account that needs the access. I find it's best to fire up FileMon, filter it to the name of my database (with wildcards), and check out the properties of the error that shows up. Viewing the properties will show you the user that is actually trying to access the file.

For Access databases, you want to make sure that you're modifying the permissions of the folder and not the file. You'll need Modify permissions on the folder so that the .ldb file can be created.

Check that the IUSR account has permissions on the Access database and the folders/sub-folders containing it. I've found that on occasion if you rename or compact an access database it loses IUSR priviledges so appears in use / locked

I had the same error on Access DB : Provider error '80004005' Unspecified error

Reason was that one of the pages included files was not in the right format (UTF-8) but ANCI When I changed that file to UTF-8 , everything woked right !
