Simon contacted me earlier this week with regards to a problem he encountered with migrating user profiles over to a Small Business Server 2003 Domain.  The particular problem was around joining a Vista Business PC to an SBS domain - sounds straightforward on the surface, however, the Vista PC had some private user settings, which prevented migration:

"The following user settings are private:

- UserName

Client Setup cannot migrate private settings. On computers running Windows XP Professional, you can make these settings public and migrate them as follows:

Log on using the username and password of the user whose settings you want to migrate. In the Documents and Settings folder, right-click the user's folder, click Sharing and Security, and clear the Make this folder private check box. Repeat this procedure for all subfolders that have this check box selected, and then click OK.

Click Start, click Run, and run the Small Business Server Network Configuration Wizard again by typing: http://servername/connectcomputer.

For computers running Windows 2000 Professional, or if the above steps do not resolve the issue, see http://go.microsoft.com/fwlink/?LinkId=19069 for more information."

Although the articles are aimed at XP and Windows 2000, you can still use the information to solve the problem.  Thanks to Simon for giving me the info!
