My profile all of a sudden changed from userid to userid.this_computer in Windows 2K

I have been logging on my personal computer which uses Windows 2000 for years as "MyUserId" and using "MyPassword".  Today all of a sudden logging on with the same userid and the same password my home directory all of a sudden changed from "MyUserID" to MyUseriId.MyComputer".  Of course the computer setup a new profile for me with all my favorites, Outlook settings, desktop settings, optional settings for all the software I used are reset to the defaults.  My old user account is there it's just not linked to me.  I've seen this before on other computers but now it hits home!  Can anyone help?

This can happen when a profile becomes corrupt, a new user is created with the same name, or the domain information is changed. You can take ownership of the old profile and copy it to the new one

This articla pertains to Windows XP.  Will it work with Win 2K?
Yes.  It also can occur when you remove the computer from the domain and add it to a work group and log in with a user that already had a profile on the computer.  If you remove and add the computer from the domain multiple times as it creates a new profile to prevent data from being over written.

the article you recommended only covers changing ownership.  You said to copy the profile folder to the new user what if I edit the registry to have the user point to the correct folder for their profile?
Rather than copyng on folder in place of the other?  Seems like a better way to go.  Or, does the fact that the original profile was corrupt affect whether I should copy the folder or change the registry?

Hi, progress to date:  Changing ownership doesn't seem to be necessary since I am the owner of both the old profile folder and the new one.  What I did was go into the registry and changed the profile directory for myselt back to the old profile folder and it worked fine. Didn't have to change anything.  I've been using it for about a day now and it's working correctly.  I will delete the profile directory that Windows created and see if that affects anything else.
