NAS connection issues

Question

Hi All,

I hope you are able to help \ offer advice.

We have a strange issues whereby our new NAS has been setup and the connection attempts are very intermittent. It works some times and then all of a sudden 20 seconds later it will not connect. Then after a period of time it will connect again.

I have checked the DNS records and they all appear to be fine. We are unable to ping from the NAS box to the DNS server as we have PING restrictions in place. The NAS itself appears to be setup correctly and the groups in AD are correct. All users in the groups that access the NAS devices have Full Access to the shares. We continue to get these errors when testing the new NAS box.

We are beginning to think that it might be a networking issue, but I wondered if anyone has had any similar experiences.

Any advice or help would be greatly appreciated.

Regards.

Hello ,

Thank you for posting in Microsoft Community forum.
Based on the situation you described, here are some possible causes and solutions for your reference:

1. Check whether the network connection of the NAS device is stable. Make sure that the network cables are well connected and that the ports of the switch and router are not faulty.
   If your NAS is connected to a switch, try changing the switch's port or connecting directly to your router to see if the problem persists.
2. Make sure that the IP address of the NAS does not conflict with other devices on the network. You can confirm this by looking at the allocation of the DHCP server.
3. Check that the network bandwidth is sufficient, especially under high load. Use network monitoring tools to view network traffic and latency.
4. Make sure that the firewall settings are not blocking connections to the NAS.
5. Try connecting directly using the IP address of the NAS instead of the DNS name to see if that improves the stability of the connection.
6. Make sure that the firmware of your NAS is up to date, and that the firmware of your network devices such as switches and routers should also be kept up to date to fix known issues that may exist.
7. Review the system logs of your NAS, which may have details about connection failures to help you diagnose the problem further.
8. Sometimes, rebooting network devices such as routers, switches, and NAS can resolve temporary network issues.

I hope the information above is helpful.
