When trying to discover accounts on a Windows Domain server I get the error 'Unable to fetch accounts' (1) Device unreachable (2) Insufficient privileges to fetch accounts.

The server can reach the remote server via DNS name and the windows service is running with Domain admin privileges.   

I'm finding it difficult to follow the prerequisites found at the link below as I'm using V9 and the instructions don't appear to be the same, I'm not able to select 'Administrator Account' as the Domain admin.

Please advise
