[Samba] Incredibly slow Roaming Profiles

[Damian Gerow]

We've just set up an internal domain, and had a single XP Pro machine join
without any difficulties.  But we need this machine (and the other handful
with it) to use Roaming Profiles, which is posing something of a speed
issue.

I have logged on, killed the 'You do not own the profile' tidbit, fixed up
permissions, and finally gotten XP to read the profile from the SAMBA server
(3.0b1).  However, it takes about ten minutes to actually log on to the
machine now that it's using a Roaming Profile.

The profile itself is something like 800k, and this is all over a 100Mb LAN.
I can see via the SAMBA logs that the profile share is opened, the profile
is loaded, and the profile share is closed in a matter of seconds, yet the
XP machine continues to say, 'Loading your personal preferences...' (or
whatever it says at logon).

Does anyone have any suggestions?

Here's a snippet from the log:

And then the client actually connects.
