A. If you are not using roaming profiles but are instead just copying a profile for another domain user on the local machine you may just create a directory under profiles for the user and copy it there as per the instructions in Q. How can I copy a user profile?
If you do this you will find that when the user logs in for the first time for whom you copied the profile, they will not use the directory you created for them, but instead a <username>.000 will be created instead. This is because a mapping is used for the user to the Profile area and if the user logs in for the first time and a directory of its user name already exists it won't use it and will instead create a new area of the format <username>.nnn where nnn starts at 000.
The workaround to this is to logon as the domain user first, logout and then copy the profile as this will setup the correct mapping of the user to profile area.
If this has already happened perform the instructions in Q. Defining the profile area to use for a user.
