DNS suffix

Posted on 2004-11-26

Ok, I have two domain trees here I joined together to create a forest.  and

if a user in my domain wants to ping another client in the domain, all he has to do is
>ping clientx

however, if a user in domain wants to ping a client in the domain, he has to use the FQDN.

I think this has to do with suffix settings if I'm not mistaken. Is there a way I can set my clients DNS, so they can ping just the computer name of the other domain. Without using it's FQDN.

    Hello dissolved,

    You can add a secondary DNS zone for on your DNS server in  2003 has a feature called conditional forwarding that handles this, just FYI.  To have a client in ping a client in, add a secondary DNS for dissolved in the spira domain.

    yep, thats what I did. I added a secondary zone.  Without the secondary zone, I was unable to even resolve

    After adding the secondary zone, I was able to resolve
    I'm guessing I HAVE to use the FQDN when I ping, since I'm pinging another domain?

    Dissolved, I just remembered something, now that I'm more awake.  if you go to the TCPIP settings and DNS tab, there is a box that allows you to add suffixes to be search for when just the computer name is pinged or communicated with.  For clients in, the search order should be first and then  just the opposite for clients in the domain.  That way when you ping let's say "computer 1", it will first try and then  DHCP can also populate this field for you.

    The DNS suffix search list is the correct place, but unfortunately, you can't use DHCP to push out the search list. DHCp can only hand out a connection specific suffix, not a list. Note that once you configure a DNS suffix list to search other domains, you'll *have* to specify the primary DNS suffix as well, as this won't be used anymore for name resolution.
    You can push out the search list in W2k with a customized group policy template; this is a "Per Computer" setting.
    Once you've imported the adm file into the group policy editor, you'll have to change the view for the Administrative Templates settings to allow for "not completely manageable policies".
