windows 2003 terminal server in windows 2008 AD domain

Hi,

I have 1 2003 terminal server in my 2008 AD domain. I create users with roaming profiles: when users logon onto win2008 terminal servers all is gone well, but when I try to logon onto the 2003 TS I reach this message.

"Windows did not load your roaming profile and is attempting to log you on with your local profile. Changes to the profile will not be copied to the server when you logoff. Windows did not load your profile because a server copy of the profile folder already exists that does not have the correct security. Either the current user or the Administrator's group must be the owner of the folder. Contact your network administrator."

What I can do?

thanks in advance
