[Samba] interdomain trusts 2 samba pdcs

[rruegner]

Hi @ll,
as i had setup a vpn ( openvpn ) and
have wins browse working nice between the 2 subnets
i wanted to setup a interdomain trust.
I did smbpasswd -a -i ... the trustaccount was created.
but 
net rpc trustdom establish robowarp results in
[2004/02/04 02:58:09, 0] utils/net_rpc.c:rpc_trustdom_establish(1789)
  Couldn't find domain controller for domain ROBOWARP
for sure i checked all network issuses,
the machines know eachother via wins dns and host files,
name resolution runs perfect.
versions are samba 3 and samba 3.01 ,
has anybody played with this features and can help me out?
Best Regards
