Hi all... I'm desperate really... so I need your help guys

I have a Western Digital My Book World Edition II NAS storage whic is a linux box inside.
It was join in to active directory, I was able to read users from AD ,everything was fine till I had to reboot the NAS. then I wasn't able to access the shares.
As I previously known solution, I rejoined the WD NAS in to the AD.
I'm able to sucesfully join the NAS in to the AD, new computer is created, but I cannot read users from it.

When I do

~ # wbinfo -t
checking the trust secret via RPC calls failed
error code was NT_STATUS_INVALID_HANDLE (0xc0000008)
Could not check secret

~ # wbinfo -u
Error looking up domain users
