    Exchange and DNS Query

    Hi,

    This is my first post so be gentle!

    I setup an Exchange server during the summer holidays. Everything is working great sending and recieving etc. However i had to dish out 2 addresses to access OWA from school and home. In school we go via mail/exchange from home we go via domainname/exchange.

    How do i set it so that we only have 1 address to access it? Whenever we type in domainname/exchange in school we just get page cannot be displayed. I have tried all sorts.

    Thanks

    This is defined by DNS. Internally you can use https://server/exchange
    Externally you have to use https://server.mydomain.com/exchange as https://server/ is not valid.

    Hopefully someone will be able to tell you the way to setup DNS to achieve what you want.

    That's not what the OP is asking.

    The error you see is often to do with the firewall/web filter that I hope you use internally. It depends a lot on the whole set up though, so we can't help much without further details.

    It is exactly what he is asking. When I setup exchange (many moons ago) I could not access the mail server using the external name internally, I assumed it was due to the DNS on the DC not knowing about the external name. It wasn't an issue for us at the time to use two addresses so I never looked at changing it.

    Accessing Exchange over the internet.

    Hi,

    Thanks for the replies so far.

    We have an internal cachepilot handling the web filtering. The firewall is hosted by our LA. The e-mail domain is hosted by Easynet. Easynet setup their DNS to point to mail.mydomain.com which is our internal mail server. I got the external IP of the mail server from the LA. The LA also opened the ports required for OWA. The cachepilot doesn't do anything other then filter i hope.

    If you need anymore info just give me a shout.

    Thanks again

    Rob

    can't you create a DNS entry for mydomain.com and give that the ip of your mail server?
    externally, our domain is school.LA.sch.uk but internally we are domain.college.internal so we set up an internal DNS domain ( that we are only authoritative for internally ) for school.LA.sch.uk we can then 'trick' any internal clients to go to the internal IP address

    From the sound of it your LEA are providing your connection etc, have you spoken to them about it?

    I think cybernerd has the right idea but its worth talking to the LEA

    Public DNS - mailserver.mydomain.com -> x.x.x.x (external facing ip)
    Internal DNS - mailserver.mydomain.com -> 10.0.0.1 (or whatever your internal IP is for the mail server)
