Thanks for the information, to use a default GPO was a simple way to try 
to encourage someone to reproduce the problem.

I already created new GPOs (this is a test domain) Using the default 
filter for a new GPO, "Authenticated users", creating a new group for 
the test clients and using that as the filter, checking it have the 
right permissions (apply), checking every guide about applying GPO to 
computers. Using OUs and using domain level GPOs.

What I find weird is that gpresult doesn't list the computer as a member 
of groups I create, only a few predefined ones:

   NULL SID
   NT AUTHORITY\NETWORK,
   This company,
   and something like "mandatory level of no trust" (Windows is not in
english)
