  • RPC over Exchange Help

    OK I have configured the following one mailbox server one CAS+HUB server I still have a 2003 exchange server in the domain.

    I have removed IP 6 from both systems, created an RPC Application pool in IIS installed re-installed RPC over HTTP numerous times.

    Still I am unable to connect I constantly get The RPC_S_SERVER_UNAVAILABLE error (0x6ba) was thrown by the RPC Runtime process.

    Its been a week now of testing ripping hair out and checking

    Try for detailed feedback to give more idea of where things are going wrong.

    More info about which server you are connecting to / which holds the mailbox

    Anything in event logs or w3c logs?

      Removing IPv6 from an Exchange server is not recommended, and is probably the cause of your problems. You may well have caused too much damage to the network stack if you have completely removed it. If you have simply disabled it, re-enable it and reboot the machine.

      You also shouldn't be creating your own Application Pools, the server and IIS should be managing that.

      The RPC runtime error usually means that something is blocking the port, but IPv6 removal can also cause this.
