samba - Apr 2006 - wbinfo -t: NT_STATUS_INVALID_COMPUTER_NAME error

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?

I recently encountered the same issue. Use "nmblookup -A xxxxxx" (from
FreeBSD, xxxxxx being the PDC) or "nbtstat -n" (on NT PDC, or
"nbtstat -a
xxxxxx" from other system) to verify that there aren't any NETBIOS 
conflicts. For me a reboot of the PDC was the solution.
