John, I have tried the suggestions you provided. I have setup Dynamic
DNS as per the Samba 3 By Example book and this is all updating
correctly. I have run the validation steps indicated in the book and all
names are resolvable and reachable via hosts, DNS and WINS.
I am not sure why winbind would need to be turned off, but seeing as I
do not need that currently, I have tried disabling it; the problem
remains.
The profile directory attributes are:
drwxrwxr-x 7 root dusers 4096 May 3 10:05 .
drwxr-xr-x 4 root root 4096 Mar 30 15:14 ..
and the share definition from smb.conf is:
[Profiles]
path = /usr/local/samba/profiles
readonly = no
create mask = 0600
directory mask = 0700
browseable = no
# guest ok = yes
csc policy = disable
profile acls = yes
# nt acl support = no
I have enabled the GPO settings:
Do not check for user ownership of Roaming Profile Folders
and
Add the Administrators security group to roaming user profiles
on the Windows XP client.
Any other suggestions will be greatly appreciated.
