httpd config issue with documentroot

Hi.  I have a server that when you address it as:

http://www.aserver.com

it works fine,

but http://www.aserver.com/index.html does not.  It responds:

Not Found
The requested URL /index.html/ was not found on this server.

If I take off the trailing /, it responds with the same thing
and adds the / back.

In all subdirectories the index.html works just fine, and without
the index.html on the root it reads the index.html just fine.

The config file has the following:

    <Directory "/var/www/html">
         Options +FollowSymLinks -Indexes -MultiViews -ExecCGI
         Order Allow,Deny
         Allow from All
         DirectoryIndex index.html
    </Directory>

Any ideas?  It is redhat ws4.

Thanks,
Roger
