Cannot log on to domain

[chrisp at global.co.za]

Hi

I am trying to log on to our NT domain
I am using the samba-2.0.3-19990228 rpm

I have a computer account on the domain

Here is a transcript of what happens

pterodactyl:~# smbpasswd -j GIA
cli_net_auth2: Error NT_STATUS_NO_TRUST_SAM_ACCOUNT
cli_nt_setup_creds: auth2 challenge failed
modify_trust_password: unable to setup the PDC credentials to machine
JHBPDC. Error was : NT_STATUS_NO_TRUST_SAM_ACCOUNT.
1999/04/16 12:31:12 : change_trust_account_password: Failed to change
password for domain GIA.
Unable to join domain GIA.

Any hints would be appreciated

Thanks
Chris Picton
