problemas con dcdiag

Buenas a todos, soy nuevo en el grupo y comienzo con un problemita
que
no puedo resolver, a ver quien me puede dar una mano.
Tengo un servidor de dominio 2003 y trato de unir otro servidor al AD
y no me lo permite, al ejecutar dcdiag sobre el servidor principal me
da el siguiente error:
Doing initial non skippeable tests

Testing server: Nombre-predeterminado-primer-sitio\SERVER
Starting test: Connectivity
SERVER's server GUID DNS name could not be resolved to an
IP address. Check the DNS server, DHCP, server name, etc
Although the Guid DNS name


(606b7f2e-9709-4f6a-97ea-542d86c1521d._msdcs.alpineskate.local)
couldn't be resolved, the server name (server) resolved to
the IP
address (192.168.0.203) and was pingable. Check that the IP
addre
is registered correctly with the DNS server.
. SERVER failed test Connectivity

Skipping all tests, because server SERVER is
