File Share/Domain issue

[IanP2022]

Hi,

I've set-up my NAS as a temp back solution, but i'm having a slight issue. I've added it to my Windows Domain and it has joined fine. I can access it via Name and IP from my 2 domain controllers fine and all works as it should but I can not access it from any other device on the network just the 2 domain controllers.

Any idea what might be causing this or a potential way of resolving it?

What happens when you try?

"can not access" isn't really revealing any error messages

[IanP2022]

"Windows cannot access \\*SERVERNAME""

Check spelling name etc - But i'm able to connect from the DC without any issue so the name/spelling is correct

[dolbyman]

and you have assigned domain user/group permissions to the shares?

Did you try to access by IP too (\\1.2.3.4 - replace with IP of your NAS)?

Yes I have. I've added individual users and domain groups.

Yes, FQDN and IP work from the domain controllers but not any of device on the network. All the servers are running the same OS with the same updates.

can clients at least ping the NAS (name or IP)?

Yes they can ping the device, they just can't see the folders via file explorer.

[dolbyman]

Do you have ABE and ABSE enabled ? (if so, that would hide shares and folders from users without correct permissions)

qnap is definitely an incompatible device for domain users. It has issues with the domain structure.

[dolbyman]

works fine here (domain user/groups with folder permissions)

care to elaborate or just rambling?

Hi Guys,

Thanks for everyone's input. I finally managed to work it out!

It appears that somehow a IP block list was populated (no idea how) it was a range of IP's typically the devices I tested were all in the blocked range, Whereas the DC's weren't. What was odd was that when you rebooted the NAS the servers in that range that was blocked worked and then after a few mins would stop. I'm assuming it takes a while for the qnap service that runs that feature to work which is what was helping to make it even more confusing and thinking it was a windows issue.
