[Samba] Profile problems

[Keith Lynn]

I have a very perplexing issue with a client machine running XP Pro 
connecting to a Samba PDC running Samba 3.0.23d. When the user logins, and 
clicks on the Start Button, none of the icons that normally show up on the 
left side are there. The name of the user is at the top, and you still 
have the button for All Programs, but none of the normal icons are there. 
The user can't run programs like Powerpoint because it constantly shuts 
down. Has anyone experienced this error before? It appears to me that 
possibly the users roaming profile is not loading completely. Does anyone 
have any idea how I can make it work normally? Thanks.
