[Samba] unable to run "net rpc join"

[feroz ahmed]

Can some one help me out in joining 3.0.28a to domain.

When i run "./net rpc join -U administrator" I'm getting error "Unable to
find a suitable server".

I have logged a bug in bugzilla #5328. Logs and smb.conf file are attached
in bugzilla.

 In fact with 3.0.28a I'm able to join 2003 server with "./net rpc join -U
administrator" command with out any problem.

Also I'm able to join 3.0.28a to active directory. "./net ads join -U
administrator" is successful.

Any help in this regard will be appreciated.
