Hi snowmonkey,
The second link I read before, and of course I tried it. No success
The first link is super, I printed it, and I will try it tomorrow, when I go there. Thank you very much! What I will try some more, I'll run a software, called newsid, on this machine. I want to give a new SID to the computer. Probably it will help. Or not
I'm interested in that registry key, what you said before. Have you found it? I'm enamoured of registry
Snowmonkey, thank you ever so much for your help
