[Samba] Doubt about Global Catalog on Samba 4

[Marcio Demetrio Bacci]

Hi

When I work with RSAT on Samba4 appear the following message: "A global
catalog (GC) cannot be contacted. A GC is needed to list the objects group
memberships. ..."
Occur, for example, when I access properties about an user or computer, as
member of or Unix Attribute tab

I have executed some tests, and for me looks like is healthy my DC.

Is there another test to verify the health of the my DC/Domain ?
