Hi all! I've tried getting RPC over HTTP working via apache 2.2.0-5.1.2 running = on a Fedora Core 5 box onto my SBS 2003, as I do not want to expose the = complete IIS server to the internet. OWA works fine, but I can't get the RPC part working at all (Outlook = tries to connect and times out after a few minutes. "Outlook /rpcdiag" = shows that no connection is established). I verified that the certificate is installed on the client, the = configuration of RPC via HTTPis fine. Exchange on the SBS has been set to be a backend server (no change when = I leave it unconfigured though). When bypassing the apache (passing port 443 directly to my IIS), the = connection is established and everything works fine. I think it's a problem how apache handles the execution of the = rpcproxy.dll. When opening https://exchange/rpc/rpcproxy.dll, a blank page is = displayed after authentication (this is how it should be). When opening https://webmail.domain.com/rpc/rpcproxy.dll, IE tries (and = fails) downloading the .dll file with the error "Internet Explorer = cannot download rpcproxy.dll from webmail.domain.com. The same problem = appears with Firefox. My apache error log shows the following: ----- [19/Apr/2006:09:49:37 +0100] "GET /rpc/rpcproxy.dll HTTP/1.1" 401 1656 [19/Apr/2006:09:49:39 +0100] "GET /rpc/rpcproxy.dll HTTP/1.1" 503 - ----- while my IIS shows this: ----- 2006-04-19 08:49:50 192.168.0.5 GET /rpc/rpcproxy.dll - 443 - = 192.168.0.2 = Mozilla/4.0+(compatible;+MSIE+6.0;+Windows+NT+5.1;+SV1;+.NET+CLR+1.1.4322= ;+InfoPath.1;+.NET+CLR+2.0.50727) 401 2 2148074254 2006-04-19 08:49:52 192.168.0.5 GET /rpc/rpcproxy.dll - 443 user = 192.168.0.2 = Mozilla/4.0+(compatible;+MSIE+6.0;+Windows+NT+5.1;+SV1;+.NET+CLR+1.1.4322= ;+InfoPath.1;+.NET+CLR+2.0.50727) 200 0 0 ----- (192.168.0.2 is apache, 192.168.0.5 the SBS 2003) How come apache shows this as message 503 even though the SBS send's it = out as 443?
