NAS connection inconsistant

I have been having a problem connecting to one of three NAS boxes on my network. Bigger problem is it is inconsistent.
The NAS drives in question are Thecus N5500 (x2) and have been exceptionally stable devices. I also have an ASUS 6204T on the same network. There are three regular computers attached to the network, a Dell Studio, a PowerSpec 418 and an Asus G75VW laptop. All software/drivers/firmware are as up to date. All running Win 10.
The Dell and the G75 have no problem seeing/connecting to the NAS drives. The PowerSpec/Windows, every now and then tells me it cannot connect to one of the two Thecus boxes (same one every time) yet if I use the Thecus setup wizard I can connect and log into both boxes. Indeed I can see the icon for all drives/computers in the Network window, but when I double click on the one I will sometimes get the cannot connect/path unknown error. Trouble shooting does nothing other than say it cannot find the error. I have tried pretty much everything suggested here and elsewhere but the only solution seems to be rebooting. I want to stress here that both Thecus boxes have the same settings the only difference are the IP addresses and the MAC addresses. Any ideas?
Thanks

Hello @SteveLJ-9054,

Your problem (and its resolution) may be similar to that described in this thread: https://docs.microsoft.com/en-us/answers/questions/422869/nas-connnection-help.html

While similar that appears to me to be referencing mapped drives as opposed to simple network connection. BTW the Thecus boxes are N5550's (denoted on the network as N5550A and N5550B) not that that should make a huge difference. Once again this morning I can see the icons for all network devices but when I double click the N5550A icon I get this 124343-screenshot-2021-08-18-100956.jpg


If I try to open N5550B I can see all the contents. Both boxes are set up the same way. I've tried turning off/on the SMB settings to no avail.
I've been told it's a problem with the switch (basic Linksys 5 port), I've swapped that out too with no difference.
And just to be clear I am no IT/network expert. All of this started after an update to WIN 10 a few weeks ago since then there have a been a couple of other updates but the problem persists.
Thanks

Hello @SteveLJ-9054,

One of the links in that thread (http://gary-nebbett.blogspot.com/2021/06/mapped-network-drive-reconnection.html) contains a section titled "Verifying whether this issue is active" - you could try those steps (replacing "Try to access the mapped network drive" with "Try to access the Thecus box".

New wrinkle. If I log in to the computer as an administrator I can access N5550A.
All other computers can access freely, including the Asus which is on the same switch.
So somewhere in the settings for my usual/standard account there is a disconnect.
Trouble is I have no clue as to what it might be or how it changed from when I was not having any problems accessing the NAS.
