  • RPC Over HTTP Service Unavailable

    Hi.

    This is my first post on forums and i have question conserning RPC over HTTP.

    So heres the thing.

    We had Exchange 2003 and upgraded it to 2007. We installed CAS server to same server computer where Exchange was. That created us little problem and Exchange eated 16Gb of memory.

    We changed CAS server to another computer.
    OWA and ActiveSync works OK. but OAW wont work.
    Everytime when you try to go to https://server/rpc folder it says Service Unavailable.

    I have tryed to reinstall RPC over HTTP and deleted rpc RpcWithCert folders and RPC from Web Server Extensions.
    Looked up registery and checked everything is right.
    Outlook Anywhere configured.
    Removed 3rd party programs from IIS.
    RPCPing wont give any answers.
    Certs are OK.

    What we havent done:

    We havent removed CAS / IIS Server from that computer.

    We are running Windows 2003 Server R2 x64 on that CAS server.

    Anyone have ideas?

    There is no upgrade from Exchange 2003 to Exchange 2007. You can migrate to Exchange 2007 or you can transition to Exchange 2007. Exactly what is running where now?

      So.

      We have one server running with Exchange 2007 and second server is now running CAS/IIS/CertSrv/RPC, both server are running with Windows Server 2003 R2 x64.

      Problem started when we changed IIS/RPC to another computer. We removed CAS role from Exchange 2007 server.
      Then we installed CAS to another server, where was 3rd party things running and certificate server. RPC over HTTP seems be up, but it keeps allways saying when i go to https://server/rpc folder that Service Unavailable.
      I have removed those 3rd party programs away from IIS and tryed to reinstall RPC over HTTP without any progress.

      Sorry about my crappy english...

        Running CAS on the same server should not have caused Exchange to use a lot of memory.
        Saying that though, Exchange will use all the memory it needs to. Therefore if you have 16gb of RAM in the machine then I would expect store.exe and other Exchange parts to use all of the memory. You bought that memory to be used didn't you?

        Unless the other server has Exchange installed on it then it cannot be used for Outlook Anywhere.
        Outlook Anywhere can break easily. If you are removing it from the server then you need to disable in Exchange first, then remove the feature. If you don't disable it first then things get messy.

        Therefore I would suggest that you disable Outlook Anywhere everywhere. Then remove the feature using add/remove programs, Windows components. After doing so remove the virtual directories from IIS manager and then run iisreset to write the change to the IIS metabase.
        After making that change, reinstall the RPC Proxy component and enable Outlook Anywhere in Exchange again.
