I had this script running on a developement box under apache and it worked just fine. Now i moved it to a production server and using IIS 5.0 and its not working. Here is the entire upload portion of the script:

UPLOAD_FILE:
{
    for my $file_num (1..5) {
        my $file = $grab_file->param("file$file_num") or next UPLOAD_F
+ILE;
        my ($base,$path,$type)=@_;
        my $file_handle = $grab_file->upload("file$file_num");
        my $buffer = "";
        
        if (!$file && $grab_file->cgi_error) {
            print $grab_file->header(-status=>$grab_file->cgi_error);
            exit 0;
        }

        if ($file) {

            $file =~ s/</&lt;/g;
            $file =~ s/>/&gt;/g;  

            fileparse_set_fstype("MSWin32");
            ($base,$path,$type) = fileparse($file,'\..*');
            my $type = lc $type;
            my $uploadedfile = $base . $type;

            $uploadedfile =~ s/[^\w.-]/_/g;
            if ( $uploadedfile =~ /^(\w[\w.-]*)/ ) {
                $uploadedfile = $1;
            } else {
                error( $grab_file, "Invalid file name; files must star
+t with a letter or number." );
            }

            # This will create the new file in the new location
            until ( sysopen OUTFILE, UPLOAD_DIR . $uploadedfile, O_RDW
+R|O_CREAT|O_EXCL, 0777 ) {
                $uploadedfile =~ s/(\d*)(\.\w+)$/($1||0) + 1 . $2/e;
                $1 >= MAX_OPEN_TRIES and error( $grab_file, "Unable to
+ save your file. File 1" );
            }
            
            # The file needs to be set to binmode in order to save it 
+on a Win32 system
            binmode OUTFILE;
            binmode $file_handle;
            
            # This will write the info into the new file
            while ( read($file_handle,$buffer,BUFFER_SIZE) ) { 
                print OUTFILE $buffer; 
            }
            close OUTFILE;

            my ($dev,$ino,$mode,$nlink,$uid,$gid,$rdev,$file_size,$ati
+me,$mtime,$ctime,$blksize,$blocks) = stat($file);

            # This will store the file and size in the database
            push @statement,"INSERT INTO documents (record_id, documen
+t, size) VALUES ('$record_id', '$uploadedfile', '$file_size')";
        }
    }
