[Samba] Intermittent "Network name cannot be found" error when accessing XP roaming profile

[David Wilson]

Hi guys,

How are you ?
I've installed samba-3.0.7 from source on a Slackware Linux 10.0 server 
configured with "--with-ldap" as a backend (OpenLDAP-2.2.13) and with 
nss_ldap installed. I have my profiles share configured as follows:
[profiles]
comment = Profile Share
path = /data/profiles
writeable = yes
guest ok = yes
browseable = no
profile acls = yes
csc policy = disable

Permissions on a user's profile folder:
drwxrwxr-x  12 pupil Domain Admins 424 2004-10-14 13:46 pupil

Most of the time logins from Windows X.P. (SP1) PCs work perfectly and 
the roaming profile comes across, however sometimes an error "Cannot 
access roaming profile.... ... ... .. network name cannot be found" 
comes up.
The error is intermittent and does not seem to stick to any sort of 
pattern. I've looked all over and found that other people have 
experienced the same problem but I can't seem to find a solid fix for it.
Perhaps installing X.P. Service Pack 2 will sort it out ?

Can anyone point me in the right direction on how I can resolve this 
problem ?
Thank you for your time.


David.
