[Samba] "A device attached to the system is not functioning"

[Frode Lillerud]

Hello, 
 
Samba 3.0.2a, Debian linux, 2.6.x kernel, PDC server, WinXP clients.
 
When I try to log in on a XP client I get this message:
"A device attached to the system is not functioning"
 
I have tried google'ing for the error, but to no avail.
 
I have earlier created a user (anna), which can successfully log in from
my laptop. When I try to log in with anna on my workstation, I get the
error above.
 
If I type the wrong password, I get the normal password-error message,
so it seems like it's able to recognize the user and password.
If I log in with my local adminstrator, and open the share \\server
<file:///\\server> , I get a box for username and password. Typing anna,
and her password here gives me access to the samba shares, so also here
it looks like the user is functioning properly.
 
The log-file says something about schannel. I've tried having default
schannel settings, and also the ones I have in the smb.conf below, but
no change.
The log-file also talks about "conflicting domain portions", but I'm not
sure what that means.
 
The samba_workstation.log file (debug level 1) says:
