error: No protocol handler was valid for the URL ...

Hello,

I tryd to setup RPC over HTTPS for Exchange 2003 with a Apache 2.0.55
(Debian) as Proxy

OWA and OMA works great, but if I try to access the
https://myserver.de/rpc or https//myserver.de/rpc/rpcproxy.dll ...

I get this --> Forbidden (You don't have permission to access /rpc on
this server.)

and in the apache2 errorlogs, I see the following warnings

[Fri Jan 20 14:26:46 2006] [warn] proxy: No protocol handler was valid
for the URL rpc/rpcproxy.dll. If you are using a DSO version of
mod_proxy, make sure the proxy submodules are included in the
configuration using LoadModule.

[Fri Jan 20 14:27:14 2006] [warn] proxy: No protocol handler was valid
for the URL /rpc. If you are using a DSO version of mod_proxy, make
sure the proxy submodules are included in the configuration using
LoadModule.

I have search at google and so on, but I didn't find a solution.

I think the apache don't no how to handle with the *.dll file

I have load all that modules with symbolic links under the directory
"mods-enabled"

cgi.load
expires.load
headers.load
mime_magic.conf
mime_magic.load
php4.conf
php4.load
proxy.load ---> (loads proxy_http automatically)
proxy_connect.load
proxy_ftp.load
proxy_html.load
rewrite.load
ssl.conf
ssl.load
unique_id.load
userdir.conf
userdir.load

and the command apache2 -l shows the following modules as hardcoded

Compiled in modules:
core.c
mod_access.c
mod_auth.c
mod_log_config.c
mod_logio.c
mod_env.c
mod_setenvif.c
prefork.c
http_core.c
mod_mime.c
mod_status.c
mod_autoindex.c
mod_negotiation.c
mod_dir.c
mod_alias.c
mod_so.c

I didn't change the apache2.conf

here is my httpd.conf
