I had the RN10400 NAS for some time, it worked properly. A few days ago I installed some update to Windows 10, it is now V 1511 (Build 10586.36). Since then I cannot access the NAS: I tried reconnecting the drives, inputing the adresss into various browsers, via the network (where it is still detected, but cannot be accessed) etc.
All the time windows behaves, as if there was disconnected.
All other devices I have in my home, including another PC, a tablet and even an amazon fire stick can access the NAS without any problems just as before.
The only thing that changed (as far as I know) was the recent windows update.
I realize this seems to be a Windows problem, but so far I did not receive any help from Microsoft.
Re: Cannot access RN10400 NAS since Windows 10 update
It might also be worth running CMD on the PC and entering
net use * /delete
net use t: \\nasipaddress\data /user:admin adminpassword
where nasipaddress is the actual IP address of the NAS, and adminpassword is the actual admin password of the NAS.
The first command terminates open connections the PC has (it won't do any damage, and doesn't delete anything). It will give you a list of those connections and ask you to confirm.
The second maps the NAS data volume to drive letter t. If you are using flexraid in the NAS you might have set up a different volume name (data is the default).
Let us know what happens (in particular any errors you see on the second command).
Can you connect from this PC to other devices on your network?
There are no other devices to connect to - all other devices (other PCs, Fire stick) etc are shown, where they are supposed to, but they are not so configured, that I can log in. If I click on the other PC, it asks me to enter username and password, so I guess if there were shared folders it would work.
If that would help, I could try to set up some device to try it.
Which firmware are you running on your NAS?
6.4.1
Are your PC and NAS in the same workgroup?
yes.
and as said, all other devices in the workgroup continue to work with the NAS.
In the meantime I tried to access to the NAS via my mobile phone and another laptop, worked perfectly fine, just as before.
the laptop also runs Windows 10, as does the other PC.
also I reveiced an answer in the microsoft community answers forum which was "Your Windows question is more complex than what is typically answered in the Microsoft Answers forums. Please post your question in the Technet forum." which I did, but it was a few hours ago and I did not receive an answer yet.
I have not the slightest idea, what the problem could be, so I mention this:
there is another thing I forgot which I changed recently: I installed the most recent drivers for my nvidia graphics card (GeForce GTX 980 Ti, Version 361.43).
In the past I have never received any answer in their costumer support, so I have not asked there yet.

Hi ihaul,
Welcome to the community!
Could you post a screenshot of the error message? I also suggest that you install the SMB plus add-on (found here) and try other SMB versions available.

Re: Cannot access RN10400 NAS since Windows 10 update
Thanks for all your help.
I installed SMB Plus and used the CMD commands, during which afterwards everything worked again as it did before. I did not check in between, so I am not sure which fixed it.
Anyway, so far everything works as it did before
PS: In the meantime I also received answers on the MS-forums:
We’ve received many similar report about network discovery issue with 1511 build Windows 10, especially NAS server. One of Potential issue the mapped drive doesn’t get alert that the Network Disk is available again unless click it in this PC or ping the address again. Sometimes it work properly but gone again after a while.
No definite fixes but appears on different case.
If SMB protocol is being used, the method mentioned (temporarily disable high version of SMB) might work, we could give it a try.
