[Samba] wbinfo -t: NT_STATUS_INVALID_COMPUTER_NAME error

[Sergey Matveychuk]

samba-3.0.21b on FreeBSD 6.0 and NT4.0 as a PDC.

After joining to a domain I can get a users list and a groups list with
wbinfo -u|-g but authentication does not work and when I try wbinfo -t
I've got the message:

checking the trust secret via RPC calls failed
error code was NT_STATUS_INVALID_COMPUTER_NAME (0xc0000122)
Could not check secret

Just one time it worked after I've restarted winbind, but next time I've
restarted it, it stops work again.

Any help please?
