RPC Proxy can't be pinged._ A Web exception occurred because an HTTP 405 - MethodNotAllowed response was received from Unknown.

    Question

  • Hi all,

     

    I downloaded the RPC tools from the microsoft site, exactly the rpcping tool.

     

    on the Command Prompt I wrote:

     

     

    rpcping -t ncacn_http -s exchangesrv -o RpcProxy=exchangesrv -P"user,domain,password" -I"user,domain,password" -H 2 -u 10

    -a connect -F 3 -v 3 -E -R none

     

    and it gave me the result:

     

     

     RPCPinging proxy server exchangesrv with Echo Request Packet
       Sending ping to server
       Response from server received: 401
       Client is not authorized to ping RPC proxy
       Ping failed.

     

    this is the explanation for this Error:

     

    Response from server received: 401 
    Client is not authorized to ping RPC proxy
    You receive this response if the RPC Ping Utility test failed. The PRC Ping Utility test may have failed if HTTP access is denied, if there are incorrect credentials on the –Pswitch, or if the user exits.

     

     

    In the IIS snap-in, on the Web Site tab, on the TCP port it is 80 and in the SSL port it is 443, and the IP is the IP address of the Exchange Server(it's on one machine with Windows 2003 Server).

     

    Can Someone help me, please. I want to Run the Outlook outside and I think this is the prevention. It is a certificate error or what ??? I have a self signed certificate, which I imported in the Root Certificate Authority

  • Hi,

    Let’s begin with the following article:
    http://support.microsoft.com/kb/831051/en-us
    The error you mentioned above may be caused by that HTTP access is denied or credentials is incorrect on the –P switch.

    Thus, let’s try the troubleshooting below:
    1. check if enalbing Outlook Anywhere and install the RPC over HTTP component. Because  external Outlook clients use Outlook Anywere connect to the Exchange server:
    http://technet.microsoft.com/en-us/library/bb123542(v=exchg.141).aspx
    2. since it’s a self-signed certifictae in your environment, please check if you have installed the certificate on all outside clients.

    Additionally, to narrow down the cause, we can use ExRCA to check Outlook Anywhere connectivity:

  • Hi,

    Sorry for delay reply.

    As far as I know, 405 errors often arise with the POST method. Thus, we can use Network Monitor to confirm it:

    http://support.microsoft.com/kb/812953/en-us

    Alternatively, I’d like to confirm if there is any firewall or some other device blocking the method in your environment. And we can use a local computer to test it.

    Best regards,
