NTUSER.DAT is the users registry hive. You are probably trying to move a hive that belongs to the account that you are currently logged on as. Don't worry about this.
That aside.
Before you start doing this, make sure you create an additional account with admin rights so you can troubleshoot and backout if you screw up.
1. copy the profile to the new location;
The way you have moved the profiles is wrong. Move it all back. After you have done this Rt Click on My Computer and select Properties. Choose the User Profiles tab. Select the specific profile and select copy. In the following screens specify the location you want. Unless you copy the profile as just mentioned, not all the information will be copied and it will fail when you try to logon.
2. Redirect the profile path to the new location;
Rt click on My Computer and hit Manage. Expand users and groups. Select Users and in the right hand window rt click on the specific user and select the profiles tab. Specify the location that you want the users profile to be. You can even do this for the current account you are logged in as. MAKE SURE YOU MOVE THEIR PROFILES PROPERLY FIRST.
3. Create an account called default and make the changes to this account. Now everytime you creat a new account, start by copying this account. That way all new users will have the proper redirected profile points.
P.S. Next time don't be so stingy on the points. This should have been a 800-1200 point question as it was networkrelated and required many paragraphs to answer and you needed a step by step guide.
