Dear Johan,
This is result of the DCDIAG /A
Domain Controller Diagnosis
Performing initial setup:
Done gathering initial info.
Doing initial required tests
Testing server: Default-First-Site-Name\SERVIDOR10
Starting test: Connectivity
689ae150-dce3-449c-a467-a61617c50c76._msdcs.empresa.com.br'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
(689ae150-dce3-449c-a467-a61617c50c76._msdcs.empresa.com.br)
couldn't
be resolved, the server name (servidor10.empresa.com.br) resolved
to the
IP address (200.111.111.111) and was pingable. Check that the IP
address is registered correctly with the DNS server.
