All shares disconnect after some time

[exeter_acres]

I searched... didn't find...
So... Truenas 13.0-U4 has been running flawlessly for months....
Just recently randomly I lose all connection to ALL shares on the server...
PC I use to access server is a Win11 box. Everything will be working fine then poof
I can "See" the server in the Network window... but cannot connect to any of the shares.... no specific event has happened
Can still log on to the server via the Web interface console no problem...
Only way I can reconnect is to reboot my PC (not the server)
Tried disabling the NIC and reenabling, etc. etc

Any thoughts on why this might be happening and where to look?
Thanks

From your description, looks like the Event logs in Windows would be the first place to look... if the whole thing is solved by a Windows reboot, then not much we can recommend here from the TrueNAS side.
