[H] Network Problems

[Steve Tomporowski]

The configuration is this, the router goes to a switch, which feeds the 
main computer, a Stora and a server running Unraid.

The situation:  I was copying files from the Unraid server to a USB 
memory on the computer when things got flaky.  The connection seemed to 
be timing out (I wasn't watching it all the time). Finally, the computer 
lost all connectivity.  I've restored internet access, I can access the 
Unraid server via a browser, but neither the unraid server or the Stora 
now show up in File Explorer.  Refreshing network doesn't find them.  
I've tried several reboots, of the computer, the stora, the server, the 
switch and the router.  Updated the router firmware, updated the 
computer network card drivers.  File explorer remains stubborn. Anyone 
familiar with this?  Can't seem to find anything resembling my problem 
on the net, so far.

Thanks....Steve
