I'm running BE2014 (fully updated) on a Win 2012 R2 server. I'm trying to add a Synology NAS as a file server - no agent can be installed, and it doesn't support NDMP, so I'm just wanting to backup the files available through Windows share (which is all of them).
User shares are enabled, and I've added the BESA to domain admins (which seems excessive, but I wanted to make absolutely sure it wasn't permissions). From the BE server, I can ping the NAS, and vice versa, and there's no firewall between them. I can pull up the shares in Windows Explorer with no issue. The NAS is joined to the domain and getting its credentials from AD, and the domain admins are all NAS admins.
However, when I try to add it as a file or NDMP server, I get "The server was unable to complete the requested operation. A communication error occurred when attempting to connect to this server. Some common causes for this error are: the computer name is typed incorrectly, the computer is not powered on, a Backup Exec agent is not installed, or the network is improperly configured." I've tried using the FQDN and IP both, with the same result. I've added a number of Windows machines and a Linux machine with no issue. We have sufficient licenses as well.
What am I missing here? Thanks!
