Could be one of several reasons. Your DNS domain name is Testlabuk.local
but the NetBIOS domain name is Testlabuk. A ping to Testlabuk assumes a
NetBIOS query and the Windows client will look at a WINS (or LMHosts file)
before trying DNS. If not Lmhosts or WINS is configured, the Windows client
will look in DNS in the zone matching it's domain membership
(Testlabuk.local) and then in other zones according to it's DNS Search
Suffix. When all of these fail an error will return such as you have
received. I don't think an A record matching the NetBIOS name of the domain
is created automatically in DNS when you build a domain. If you create an A
record called Testlabuk in the Testlabuk.local zone it will work. But I
would not do that as it can cause confusion. If you install WINS these
problems will go away. Some AntiVirus, Backup software and Exchange needs
NetBIOS functionality so you should install WINS. Legacy clients such as
Win95/98 and NT 4.0 also need WINS to find the domain.
