CIFS and Web UI not responding

[Zorin1]

I need some help figuring out what my problem is. About once a week my CIFS shares and Web UI do not respond. I also have Plex installed and I can connect to this. When I look at /var/log/message I see bunch of these messages:
Feb 15 16:43:43 nas2 smbd[94510]: [2016/02/15 16:43:43.232203, 0] ../source3/lib/util_sock.c:1199(get_remote_hostname)
Feb 15 16:43:43 nas2 smbd[94510]: matchname failed on 192.168.1.153

Feb 15 21:18:04 nas2 smbd[2170]: [2016/02/15 21:18:04.745253, 0] ../source3/lib/util_sock.c:1199(get_remote_hostname)

This is from log.smdb:
[2016/02/15 16:43:33.342929, 1] ../source3/smbd/service.c:1130(close_cnum)

matchname failed on 192.168.1.153

Can anyone tell me what is going on where I need to look?

thanks

In [Network] - [Global Configuration], do you have any DNS Servers added there? They are the "NameServer" entries...

No, it is using DHCP to setup the network. Do I need to put something in there?

I would recommend that you should have at least one entry for your DNS Server (which may/should be your router IP). Your router may be providing this, but I am not sure how you have it setup.

Also, it is better to either assign FreeNas a static IP that is outside of your DHCP Range or a Reservation (based on MAC) on your router.

If you assign a static, then you will want to enter a "IPv4 Default Gateway" as well. This is usually the same IP as your router as well.

I do have it set to a static IP, the DHCP always gives it the same ip address. I did not see where you set the static IP address. Do you have to do this from the console?

I usually do it from the console from the start (not from the shell). It can be done in the GUI: [Network] - [Interfaces] as well.
