samba - Jul 2002 - api_netlog_rpc: NET_SAMLOGON failed

Hi,

I've got a RH72 box called FILESERV acting as a PDC for a while now.
It's been doing fine with Win2k clients. The version of the PDC Samba is
2.2.3a-1.

I've now added a RH72/samba-2.2.1a-4 machine called GOA to the domain.
I've set it to use FILESERV as the password server. On GOA I created a
local linux user that's name matches the one in the Windows domain
(peter). It does not seem to work: When I try to access the "juuri"
share on GOA from a Win2k client, my authentication is not accepted.
This error apperas in the PDC's logs:

--<snip>--
[2002/07/17 14:53:23, 0] rpc_server/srv_netlog.c:api_net_sam_logon(206)
  api_net_sam_logon: Failed to marshall NET_R_SAM_LOGON.

  api_rpcTNP: api_netlog_rpc: NET_SAMLOGON failed.

Nothing in GOA's logs. What might be wrong? I created a local account
for root on GOA with smbpasswd -a and that seems to work fine.

GOA's smb.conf:
