child domain NetBIOS pingable but computer name is not.

i create a child domain for a branch office childone.xyz.com, before this we had two other childs in other branch offices. now what is happening is that when i ping from head office to child domain NetBIOS name; the response is successfull. but when i ping to the server (computer name) it doesn't.

You'll have to edit your dns search suffix list to include the child domain. The dns suffix search list must include childzone.xyz.com.

bogdan_onutaCommented:
you can do it via group policy. open the group policy editor console, navigate to computer configuration, administrative templates, network, dns client. Change the dns suffix seach list to include both the domain and the child domain. So the list in your case must be domain.com,child.domain.com. The list MUST be comma separated and there must not be a apace between items in the list.

Cheers and good luck.
