[Samba] XP not saving profiles

[rowland penny]

we need to move from a workgroup to a domain and not wanting to make the 
worlds richest man any richer ;-) I thought I would give samba a try

downloaded Kubuntu 5.10

followed howto on howtoforge

I can log in and out as administrator ok but any changes do not come back
If I logon as a user I get the following when I log off

Windows cannot copy C:\Documents and Settings\"username".FILESERVER\sendto
to \\FILESERVER\profiles\"username"\sendto

I have RTFM ( not saying I understood all of it )
I have googled on this subject
I have tried various alterations to the smb.conf file after doing the above
I have also altered the registry after googling etc (signorseal for example)

Can anybody suggest where I am going wrong or offer any advice please.
