FirePower Remote Storage Management

[-Sparrow-]

Hello,

I've bee trying for a while to get my FMC to talk to remote storage so I can place my backups and reports there. For some reason my FMC refuses to talk to any remote storage device I have.  NFS, SMB (haven't tried SSH), neither work. I keep getting an error:

All passwords and usernames that I've tried are getting the error... Am I missing some kind of formatting here?  I use domain\username format or username@domain format. I've also just used the username.

Can someone please shed some light on me here?

Thanks!

I just tested it in my lab and it is working fine. FMC 6.5 to Windows Server 2016 with SMB sharing.

Here are the respective settings I have made:

Hi Marvin,

I thought maybe it had to do with the SMB version so I turned on SMB v1 but that still won't connect.  I used the exact same formatting as yours and I get this:

I have the verified the share permissions and the user has R/W on it.

What else can I be missing here? 

Thank you.

The error message is quite ambiguous. Perhaps a packet capture on the target SMB hosting server would be informative.

Hi Marvin,

Wireshark shows the SMB Negotiate Protocol Request being sent from the FMC but the destination host sends a RST flag resetting the connection.

I have no clue what could be causing this.
