    .local vs .com

    If one installs exchange 2003 with the .local instead of .com extension. Do
    you kill 100% conectivity for outlook clients from the outside world.

    All of my staff can connect internally but but from home. If an employee
    types in from home the exchange server IP address or DNS name outlook clients
    initially finds the user, CONVERTS the exchange server name to
    Excahnge.MyDOmain.local and continues the setup with no problem. However,
    once its profile is changed to local. The outlook client can no longer
    connect to the exchange server.

    Is .local dooming me?

    I think this is more of a DNS name resolution issue.

    When you create an Outlook Profile, the OL client will pull down the
    NetworkAdress attributes that contains the "name" for the Exchange server.

    Outlook will then choose the name for the protocol that it is trying to use,
    in most cases the ncacn_ip_tcp name and that will be the Internal FQDN of
    the server.

    Long story short is that you will need to create HOSTS files on your
    external clients that point the internal fqdn to the external IP address of
    the exchange server.

    Hope this helps.

    No. If you're using RPC over HTTP(S), which I presume you are, see
