I am running an Outlook Connectivity test using the Microsoft Remote Connectivity Test and it seems to fail on the last test. We are running Windows Server SBS 2003. Does anyone have any suggestions?

The HTTP authentication test failed.

An HTTP 403 forbidden response was received. The response appears to have come from IIS6. Body of the response: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">

This is caused if you have IIS configured to reject connections from specified domains or IPs.  There is a good document from Microsoft which explains this:

http://support.microsoft.com/kb/248043

Follow the document and add required domains/IPs to the allowed list (or remove them from the reject list).

If I choose basic as the authentication method then the error is


      Attempting to ping the MAPI Mail Store endpoint with identity: server.mydomain.local:6001.
       The attempt to ping the endpoint failed.
        Tell me more about this issue and how to resolve it
       
      Additional Details
       
The RPC_S_SERVER_UNAVAILABLE error (0x6ba) was thrown by the RPC Runtime process.

Go to IIS and change Authentication from Basic to NTLM.

I changed the valid ports to 100-6100

Open Registry Editor on the Client Access server or on the front-end server, and verify that the ValidPorts registry value exists under HKEY_LOCAL_MACHINE\Software\Microsoft\Rpc\Rpcproxy. Also confirm that the key includes the NetBIOS and FQDN for all mailbox servers and for each required port (that is, for ports 6001, 6002, and 6004).

Troubleshoot name resolution, and verify that the server acting as the RPC proxy can correctly resolve the internal fully-qualified domain name (FQDN) of the mailbox server or of Exchange 2003.

I can ping and do a nslookup on server.mydomain.local

To test endpoint connectivity, open a Telnet session on the Client Access server or on the front-end server, and then Telnet to each port on the mailbox servers (that is, on ports 6001, 6002, and 6004).

I can telnet to these ports from a client computer

I managed to resolve the issue by following the article below.

HKEY_LOCAL_MACHINE\Software\Microsoft\Rpc\RpcProxy



Value name: ValidPorts

Value data: ExchangeServer :6001-6002; ExchangeServerFQDN :6001-6002; ExchangeServer :6004; ExchangeServerFQDN :6004


Note:   * ExchangeServer should be the NetBIOS name of Mailbox server.

   * ExchangeServerFQDN should be the fully qualified domain name (FQDN) of Mailbox server.
