[Samba] WinXP SP2: problem loggint into domain

[ayach-asu]

I have applied the registry patch:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\netlogon\
parameters "RequireSignOrSeal"=dword:00000000
Fine add my machine to the domain.
When I reboot machine and login to the domain from a Windows XP
Professional SP2 I get the following message:

Windows cannon connect to the domain, either because the domain controller
is down or otherwise unavailable, or because your computer account was not
found.

Help me.
Victor.
