From outside our network, resolves to my internal website.  From outside my network resolves to my website.  But internally on our network does not resolve to anything, let alone my website.  What DNS record am I missing?

    >>>From outside our network, resolves to my internal website.  From outside my network resolves to my website.
    What exactly this means??

    You mean, Your Internal and External DomainName are same i.e.
    YOU AD Domain is also

    and you external users are pointed to your wesite that is hosted internally on a webserver.
    and your internal users are not pointed to the internal website when they type
    Is that rite???

    The Host record of the Internal DNS Server (which the Local Machines refer to) do not have the Host record point to [or]

    Hence add the Host record to point to the Webserver (if you want) for or

    The internal machines can find the website by typing  I have a dns record for www.  They just want to find the website by typing  Without the WWW.  What dns record am I missing?  DNS will not accept just the domain name like ""

    The DNS record that would direct to your web server would be a Host (A) record in the fwd lookup zone for If your internal web server has an IP address of 192.168.x.y then it would appear as follows when viewed from the DNS management console:

    (same as parent folder)      Host (A)        192.168.x.y

    However, the configuration of your AD domain and servers is relevant. As requested in another comment, you need to confirm in more detail what you have because the Host (A) record for would normally need to point to your domain controller. If your internal web server is not also your DC, then what you want may not be possible.

    Yes the MYDOMAIN.COM is also the name of my AD domain.  So internally I cannot point MYDOMAIN.COM to resolve to my internal web server?  It does just fine externally.  It works both internally and externally just fine using  Just my webmaster wants it to resolve by

    I do not think that you should re-direct the Host record for on your internal DNS server if it is pointing to the domain controller now. Doing so might confuse AD, although I cannot say for sure on this matter. Furthermore, if you do change it, you might find that Windows changes it back again all by itself - things like that happen when the domain controller re-registers itself using DDNS (which is very likely how your DC is configured).

    If and both resolve correctly externally, I would guess that this is because is hosted on a completely separate public DNS server. It is very common to have separate internal and external DNS servers - the internal one has records describing things on your LAN and for various reasons, including security, you would not want that information to be available on public DNS servers. The public one, usually owned and run by an external agency, would only have records describing how to reach your web sites, your e-mail servers, etc.

    Many companies use a different name for the internal Windows domain (e.g. mydomain.local) and external Internet domain (e.g. This is done to avoid the type of DNS conflict that you now have.
