  • naming external dns records without giving too much information

    hi there,
    I'm installing a new exchange 2007 server and I was wondering if anyone has any tips about what names to give it in our external dns zone.
    If I use mail or webmail, anyone who searches my dns zone will immediately see that it's a mail server. Any bot out there can easily determine that.
    The worst part is that I have to put autodiscover.myDomainName.com.au on my UCC SSL certificate. This basically tells anyone who wants to know that I'm running Exchange 2007.
    I'm trying to avoid this in a way that I would name my external servers by not calling them mail or vpn or whatever.
    I realize I can just come up with random names but was wondering if anyone has given this a though before and has a cool naming convention scheme.
    After all.. It has to be cool.
    Thanks,

    Everyone likes Dave.

    Brits amongst us will get the reference to trigg.domain.com

    Pick a naming scheme you like. Constellations, mythical heroes, diseases (my supervisor at a previous job got into a decent amount of trouble for naming the servers at a school after STDs...)

        What he said. It'll take half an hour, if that, for a crawler to find what subdomains you have setup. Focus on securing the services that those subdomains point to. If you use obscure names, you may get a queue of users outside your door who got confused, and electrifying door handles is probably against company policy.
