    NO!!!! Use smith.local or smith.internal or smith.secret, or whatever
    extension you want.
    Your life will be simpler... if you keep it simple.

  3. You can either use smith.local or smith.pri for your domain name and setup
    internal DNS using that format. Pointing all internal clients to internal
    DNS (this includes your DCs!) Make no reference to external DNS.


    You do use (but your ISP presumably also handles your dns / web /
    mx records) and setup all your internal DNS servers as, have
    clients point to internal dns including servers and then manually add a www
    entry (a-record) in your internal DNS referencing the external IP address so
    clients will get directed to the proper address.


    Hit the MS site and read their white papers on DNS best practices...

  4. Just you if you like the name. Add one A record ( "www") and make
    the IP the public IP that it is today. Keep your public dns hosted by your
    existing party or use your registrar.

  5. Just to add to the mix, you can use as easily as using
    smith.loc. The only set up presented to you that requires more work is using But the extra work needed is explained.

    I have a simular problem, my ad intergrated domain has the same name as my
    web site now whenever we type we get page not found. I added
    an a host record with the external ip address of the web host ip address but
    still no change. Any suggustions would be greatly welcomed!

  7. When you use nslookup or dig to resolve internally, does it
    give you the correct public IP? If so, is the public IP actually NATed back
    into your private lan? If so, that is probably the issue. If not, would
    need to drill down some more.

  8. Remove the A record with the private IP keeping only the public one.

    When I run nslookup it only finds my internal ip address and not the public

    Actually I ran nslookup and it came up with two external ip addresses and
    once I put the 2nd a record in it started working. Thanks for your help

  11. It may have been your local cache (or server cache) that cached the private
    IP. Could not tell at this point. Glad it worked. Cheers!

  12. In
    Are the XP clients using the internal DNS, only.
    If not, they should, and they should use _only_ the internal DNS.

  13. Kevin gave good advise. I would check the dns servers listed at the client
    and make sure the list only points to internal server(s).

    I will check to make sure that they are using only internal DNS. Is there
    any other possible problems with this confiuration?

    Thanks JB

  15. Shouldn't be unless the internal server can't resolve external names for
    some reason.

    I am still having the same problem with the three file servers can get to the
    external web page and the work stations can not the internal DNS name is and so is the external web site. When I ping from within the
    domain all that is returned is the primary dns server of the local domain,
    and not the external web site.
