Not Able To Add Active Directory User to PCAnywhere Settings

Hello,

    I was wondering what I am missing. I go into pcAnywhere Settings - Windows, Authentication and choose Active Directory. The problem I am running into is there are no options for domain, users, groups or anything. I found this article which does explain the issue we are having but none of the options have helped out.  However Solution 9 where it talks about creating a new host.  When I follow those steps I'm not able to see our AD environment just the local NT Local Machine settings of our SMP server.

     Is there any other settings I should be looking at.  There is currently one AD user listed which is the account we created as the smpadmin.  Just can't add any other AD users or admins.

     We are using Symantec Management 7.1 with PCAnywhere 12.6

Thanks.
