samba - Jun 2004 - Unable to connect machine to Active Directory Domain

Greetings,

I have been trying, without success, to connect a linux host to the
Active directory domain of the organisation where I work.

When I use the command, net ads join -U <domain.user> password:
<domain.user.password>, it does not give back a response. 

When I run /usr/local/samba/bin/wbinfo -t, it responds with:
                          
checking the trust secret via RPC calls failed
error code was NT_STATUS_INTERNAL_ERROR (0xc00000e5)
Could not check secret
