problem with joining domain

[Galloway, Dan]

I've been trying to set up a samba server to authenticate passwords to
an NT domain, specifically to the PDC. I've tried using security=server,
and now I'm trying security=domain. The error I keep getting for
security=server is:
Connecting to 157.166.87.190 at port 139
connected to password server 157.166.87.190
write_socket(7,76)
write_socket(7,76) wrote 76
Sent session request
got smb length of 1
157.166.87.190 rejected the session

This happens on two different domains. The samba server is on a different
network subnet than the PDC. The other error I get in the security=server
mode is:
password server is not connected.

Using security=domain, I get a different error:
Connecting to 157.166.87.252 at port 139
write_socket(5,76)
write_socket(5,76) wrote 76
Sent session request
got smb length of 1
modify_trust_password: machine 157.166.87.252 rejected the session setup.
Error 
was : code 131.
1998/06/17 11:52:50 : change_trust_account_password: Failed to change
password f
or domain CNN_INTERACTIVE.
./smbpasswd: Unable to join domain CNN_INTERACTIVE.

When I use the smb-enabled tcpdump, I get this:

The part that really gets me is that I can't find a table of NBT errors to
look up that 0x82 anywhere.

I did get on the PDC and do a nbtstat -a <sambaserver> to verify that it
knows
about the samba server and that it thinks it is a part of the domain.

I'm running samba on a Sparc5, Solaris 2.6.

Thanks in advance for any help.
