  • Exchange 2007 Outlook Anywhere - Cannot resolve name

    We have an internal server running Windows 2008 x64 + Exchange 2007. CAS server running Windows 2003 x64 + Exchange 2007. Self-signed certificate on the CAS server. OWA works fine. Trying to set up Outlook Anywhere and having issues.

    Installed RPC over HTTP on the CAS server and checked ValidPorts under HKLM\Software\Microsoft\RPC\RpcProxy

    NETBIOSINTERNALSERVER:6001-6002;NETBIOSINTERNALSERVER:6004;FQDNINTERNALSERVER :6001-6002;FQDNINTERNALSERVER:6004

    Exchange management console:
    Server Configuration, Client Access, CAS server, Outlook Anywhere
    External host name: FQDNCASSERVER
    Basic authentication

    2007 autodiscovery is not working (don't have a CNAME for autodiscovery.email-domain.com just yet) and manual set up is not working either.
    Outlook profile is configured like this:
    Exchange server: FQDNCASSERVER
    User name: the user name
    Exchange proxy settings:
    Use this URL: FQDNCASSERVER
    Only connect to proxy servers: msstd:FQDNCASSERVER
    Fast networks unchecked
    Slow networks checked
    Basic Authentication

    I tried logging in with domain\user, FQDN of the CAS server\user, NETBIOS name of the CAS server\user with no luck on any.

    This is what is in the IIS logs on the CAS
    2009-08-01 04:01:44 W3SVC1 EXTERNAL_IP RPC_IN_DATA /rpc/rpcproxy.dll FQDNCASSERVER:6004 443 domain\user MY_IP MSRPC 200 0 0

    I'm sure it's something simple. I included everything I did so if I a missing anything.....let me know. Any help is appreciated!

    Is this a single server scenario? I'm not sure on Exchange 2007 but I believe in 2003 RPC had to be installed on the GC as well.

      Two servers. Exchange 2007 on Windows 2008 for mailbox and Windows 2003 for a CAS. RPC over HTTP is only installed on the CAS box.

        I take it the CAS hold your Global Catalog role?

        Being that you self-signed, are you inside the network with a machine which has a domain membership?

        Have you added the certificate to your store on the clients?

        Just throwing out ideas.

          No, it does not. It is just a member server joined to the domain. It's not a DC or GC or anything like that. I think that is part of the point to have an external CAS, so you don't have that sort of stuff exposed to the outside world.

            OK, so where is your Global Catalog role and did you configure RPC on the GC machine?

            HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\NTDS\Parameters
            Type: REG_MULTI_SZ
            Name: NSPI Interface protocol sequences
            Value: ncacn_http:6004

            Reboot the GC

            Also, is your CAS configured for basic authentication?

              I do not have that registry key on my external CAS box.

              CAS is configured for basic authentication in the Exchange Management Console under Server Configuration, Client Access, properties of the outside CAS, Outlook Anywhere, Basic Authentication.

              Unless you are talking about something else.....

                Not on your CAS brother, on the machine which holds your Global Catalog role. Probabaly the first domain controller you installed.

                  On the both GCs that registry entry is present.

                    I added a CNAME for autodiscover.emaildomain.com to point to my external CAS and I also got a legit cert from GoDaddy today and it seems to be working better. I was able to get a non-domain machine outside of the network to autoconfigure.

                    Now my freaking iPhone won't connect! I deleted the account, restarted the phone and created a new Exchange account. It does the autodiscover (I guess) and comes back with the INTERNAL server name. There's no way to get to that internal mailbox from the outside. I put in the external server name and the account verification fails.

                    One step forward, one step back.
