Windows Domain Migration -- after-thought edition
So one day you come back to work and find that your administrator set up a completely new windows domain and you were assigned a completely new user account with a completely new SID. But you don't feel like setting up your user account on your windows workstation from scratch, losing all your preferences and possibly some work and also a lot of time in the process. subinacl comes to the rescue!
You need to be a local administrator (at least, though domain administrator will probably work too) and the latest version of subinacl from Microsoft's web site. (I've been advised to only use the latest version, which currently seems to be 5.2.3790.1180.)
For the rest of this page I'll assume that your username is foo, your old domain is bar and your new domain is baz. Just in case you should also use the windows provided backup utility to completely back up the registry and your old profile directory.
