samba - Apr 2004 - Trouble with winbind + samba and NT trusts

I'm working in a good project: migration of 67 NT domains to samba +
linux based servers (12.000+ users). 

In the central server, samba 3.0 from backports.org (debian), I have 67
trusts to NT domain servers, and all works fine :-) 

PROBLEM: I need a new trust with another server, and when I proceed the
net join i receive the following error:

# net rpc trustdom establish procempa
[2004/04/26 11:43:06, 0] rpc_parse/parse_prs.c:prs_mem_get(530)
  prs_mem_get: reading data of size 4 would overrun buffer.
[2004/04/26 11:43:06, 0] utils/net_rpc.c:rpc_trustdom_establish(2030)
  WksQueryInfo call failed.

prs_mem_get: reading data of size 4 would overrun buffer <== WARNING ???

WksQueryInfo call failed <= REAL ERROR???

I need help. My english is very very very bad!!! Sorry.

THANKS FOR ALL
