Use the Administrator tools. I do not have access to my ADS server right now, 
so am going from memory. There is a tool called "Active Directory Security" 
or something similar. Suggest you check what are the policy settings 
regarding external access.

I may be off beam, but it looks like the ADS server is refusing access for the 
TCON_X call. That may be due to the Samba client not being able to support 
the encryption type, but could also be caused by policies in effect that do 
no permit access.

Later today I may be able to access my ADS server. At that time I will check 
what the admin tool is called.
