Can I move Users accounts profile to Server?

[Thinkster]

I have Windows 2003 Server R2 running with AD and the Vista business client machines are joined to the domain.

I have created a Folder called 'Users' with a shared subfolder called 'Students' on the server and have set permissions for 'Students' to have Full Access to that folder.

Now on the Vista workstation I went to User Accounts and 'Configure Advanced user profile properties'. I then select the account that shows SERVER\Student and click the [Copy To] button. I then Browsed for and selected the 'Students' folder that's shared on the server. I also again set permissions in the 'Permitted to Use' section. I get a warning message saying that the folder exists and the Data will be deleted (which is fine because there is NO data), then when I click OK, it Always errors out with "<\\Server\Students> could not be deleted. Please delete the directory and retry."

So I take it that you can't put user profiles from Vista machines on a Windows 2003 Server? I never had this problem with XP.
