[Samba] Error when add Samba 3.0.10-1.fc3 to Windows NT Domain

[Cristian Thiago Moecke]

I am trying to install a File server using samba on a NT 4.0 domain.
I will call the domain DOMAIN, the pec PDC, the samba file server SAMBA,
and so on... :D

The linux is an updated Fedora Core 3, and the samba version is 3.0.10-1.fc3

I used SWAT to configure. Here is some lines of my smb.conf:

workgroup = DOMAIN
server string = SAMBA
interfaces = eth
security = domain

Then i looked on the interrnet how to add it to a domain, and found that:
# net join member -S IP_OF_PDC -U moecke

Unable to join domain LMP.

I get this errors... I found many things about it on internet, but nothing
helped me. What should I do???

Thanks
Cristian
