install_driver(Oracle) failed

I am getting the following error when I run my script
install_driver(Oracle) failed: Can't load
'F:/Perl/site/lib/auto/DBD/Oracle/Oracle.dll' for module DBD::Oracle:
load_file:Access is denied at F:/Perl/lib/DynaLoader.pm line 206.
Compilation failed in require at (eval 2) line 3.
Perhaps a required shared library or dll isn't installed where expected

I am running Oracle9i, IIS5, perl 5.6

The script works from the command line but through the webserver/browser
