Re: What happens if a domain user leaves the network of the domain controller?
In my experience, as long as the user has been logged into the PC on the domain @ the work place, it will create that domain profile for them. Then if they log in when offline or when out of the network, it'll log in just fine but you will not have access to your work network, servers, etc. But I've RARELY had a PC fail to log in @ home that's part of a domain. We have a couple dozen users who do it all the time (mostly XP, some on Win 7) that don't have any issues.
There's no place like /home.
