[Samba] what does "Secret is bad" mean for "wbinfo -t"

[Sarris, Chris]

Hello,
I am implementing winbind with Samba-2.2.3a on a NT 4.0 network .... I
joined the domain previously with "smbpasswd -j Domain -r NTPDC -U
Administrator" and I was notified that I was joined to the domain.

Later when I tried to query and make sure the machine account was active
with "wbinfo -t" this came back:

"Secret is bad
0xc00000e5"

I have smbd, nmbd, and windbindd running in ps -leaf 
and I am able to get users and groups from the NT domain using "wbinfo -u"
or "wbinfo -g"

Any thoughts?

thanks tons,
Chris
