Default NAS Disappears

Home LAN with Win7 WinXP Win10 PCs and three Buffalo NAS.
Connected via Cat5 not WiFi.

Three Buffalo NAS in different rooms, PC too.

Something hiccuped and all Buffalo NAS disappeared from all PCs.
I have no idea what caused this !
A WD NAS did not disappear.

I checked my LAN and was able to see all other PCs from all other PCs.
Strange.

To fix it I powered down then up each Buffalo NAS and all came back
working normally.

Not a power glitch as nothing else hiccuped (microwave, clocks etc).

This is the second time this has happened, both recently.
All been running for years before this.
Only thing new is the AT&T hookup but that is isolated as WiFi to PCs.

What the heck !

An additional interesting point is that I plugged the AT&T into the
switch and now I can see PC shares that I could not before.
Too much fun for me.

Nameserving could be via NetBIOS, as the lowest common denominator.
But perhaps you have something else that performs this function.

If the devices were in a different workgroup that might explain it.

The computers on the LAN, elect a "Browse Master", which is like
your own little Domain. I don't know if that would play a part
or not. If you have Wireshark installed, you could actually watch
the packets for that, as each "election", every 10-15 minutes, would
leave color-differentiated packets in the Wireshark trace. If you
saw chaos there, that might explain why the nodes viewable via
your NetBIOS have disappeared.

Just using that silly idea, I did a Google search and found this.
Perhaps you could keep a copy of that handy the next time. What should
happen, is the three entries should just "disappear". But seeing them
disappear inside the NetBIOS viewer, you'd know there was some problem
with NetBIOS itself. It's not going to help a whole lot, but it's
a start.

You could try pinging the (known before failure) IP addresses
when the three devices disappear. The left-most column has an
IP address for each computing device. In a Command Prompt window,
from the partitioned machine you could try

ping 192.168.0.10

using the screen shot as an example. Maybe an actual routing
device on your LAN has ceased functioning or something.

Using the Buffalo app did not help.

I went to Windows Explorer Network and found that one of the NAS was
there and I was able to look at files through Network on a Win XP Pro PC.
My Win7 PC got drive letters assigned and were working OK.

I booted the Win XP PC and the drive letters came back.

I think the NAS are a different Workgroup but not sure how that plays
into stuff since for years this all worked flawlessly and only recently
have I had any problems at all.

I will look at the suggested app tomorrow.
Too tired right now to think straight.
