[Samba] roaming profiles and folder redirection: programs 'not responding'

[Heiko Harders]

Hello,

I've setup a PDC with Samba 3.0.31 and I am testing on a Windows Vista
box (64 bits version).
Often I get the message of programs that they are not responding and
it takes about half a minute before I can use them again. Especially
Mozilla Firefox has this problem often (allthough I'm using this
program the most, so it is also the most obvious).

I am using roaming profiles with folder redirection. I excluded all
folders from the profile through a registry setting and redirected all
folders in the user shell folders to network drivers, except the
folders that appear in 'AppData/Local' (so the local, machine
dependent settings are excluded from the profile and they are located
on the local disk of the computer).

Does anyone recognize these problems? Does anyone know a solution, or
the best way to troubleshoot this?

My roaming profiles are working fine otherwise, all settings are
nicely stored in the profile, I don't get any error messages and the
user has the proper rights to write to any network drive that is
needed for this user. Also I have no problems with the network
connection. I detected no packet loss and the response time is fast
(tried pinging to the server while the problem occured, average time
was 0 ms and 0% packet loss). The problem is by far not occuring as
much when I'm logged in using a local profile on the machine, so I
think it must be some problem with the PDC connecting with Vista.

Greetings,
Heiko
