[Samba] NT_STATUS_INTERNAL_ERROR

[Ricardo Pardim Claus]

Dear Rowland 
Strange thing is that I do not receive notification on my email about your answers. 

Here we run an internal DNS. Samba was configured with Bind 9 as secondary DNS. 

When I put in domain.local settings, it is because we omit the company name. But the name of my domain ends with .local. 

I disabled Avahi daemon. 

When I try to run the command you quoted: 
smbclient -k -L //srv.domain.local 

I get the same error: 
session setup failed: NT_STATUS_INTERNAL_ERROR 

The command "kinit administrator" works perfectly.
