We'll need more info...

Pinging by single name or FQDN makes a difference. If by single name, it
uses the search suffix. If pinging by single name and the machine is just a
workgroup machine without a Primary DNS Suffix, which then means the search
suffix is blank, then it will try to use only NetBIOS and if that is not the
NetBIOS name, then unknown host will be your result.

So.......

1. How are you pinging?

    ping hostb
    ping hosta
    ping hosta.mydomain.com
    ping hostb.mydomain.com

    Which ones work above on which machine?

2. Search suffix on machines?

3. What DNS addresses are on the machines?

4. Please provide an Unedited ipconfig /all from the two servers you're
trying this from (the member server and the non-member server). This will
give us a solid view of your config for diagnosing.
