[Samba] error upon logging out of XP clients

[Adam Williams]

I have a domain controller called preshs.  I have a few Windows XP 
computers using linksys wireless cards and a wireless access point that 
all connect to preshs.  The network works fine.  Logging in produces no 
errors, however when a person logs out of an XP machine they get the 
following error:

Windows cannot copy file C:\Documents and
Settings\awilliam\Cookies\index.dat to location
\\preshs\profiles\awilliam\Cookies\index.dat. Possible causes of this
error include network problems or insufficient security rights. If this
problem persists, contact your network administrator.

DETAIL - Access is denied.


Every user gets this error on all the computers. each user owns their 
profile directory, and each /var/lib/samba/profiles/username is set 700, 
the Cookies subfolder is 600, and index.dat is 700.

I don't see anything wrong with my configuration.  any suggestions?
