My New Home Network

I just finished setting up a home network(my own) with a domain controller. Till now I faced two problems and found temporary solutions:

1. Password for a new user, no matter how strong, was not accepted by AD.
   Solution: Set Password policies to Not defined.
2. The workstation froze at Applying your personal settings or Loading your personal settings for 5-10 minutes.
   Solution: Edit the Hosts file and add computer.domain.net to the list for e.g. 192.168.1.100 server.home.net
