First of all thank you for looking into it. I imagined it could be something of this kind but I couldn't find the proof. The problem is that actually I'm home working and my pc need to have the vpn activated to connect to the domain, and I can start vpn only after boot. Group policies and the restoring of network connections is forced by the company through batches which i cannot delete (if I do the system will reinstall them next time I connect to the domain). So I think I cannot do anything to solve this situation. Just for curiosity, where do you see in trace which are the problems? Bye Michele
