Cifs share constantly disconnecting in windows 10

[Nanashikun]

Hi,
I am running the most recent stable freenas 9.3 on a xeon rig with 5 3TB WD RED drives.
I have a one cifs and one nfs share and permissions work fine. When I access the share through windows 10 (I have 4 machines here running windows 10) I can access my share and all the files, but at random time the share just disconnects. That happens on all machines running windows 10, the nfs share stays completely unaffected by this. Changing the SMB version and/or MTU has no noticeable effect on this behavior. Sometimes this happens during large uploads , in that case I usually just have to try again and the upload works all the way through.
I have no idea what could be the cause of this and hope you could shed some light on this very annoying behavior.

Thanks a lot

Use device manager on Windows 10 and uncheck the box 'turn device off to save power' from the config for your NIC.

Hmm there is no such option for my nic....

What is the client's NIC, anyway? Disconnects during active use seem like more than just aggressive power rationing.

Check entries in /car/log/messages and /var/log/samba4/log.smbd. is this over a wired or a wireless connection?

Hi,
one of the affected NICs is an onboard Intel I218 Gigabit NIC running with Intels advanced Network drivers. The problems appear with wired and wireless connections alike. Before I installed FreeNAS I was running Windows 2008 R2 and later 2012 as an ESXi VM and had no such issues at all. Power Rationing shouldn't be happening while uploading files thoo.
I'll check the logs when I'm home again, maybe I'll find a clue there.

Thanks

Does this only affect NFS or is it only affecting samba sessions? If only samba, then post /etc/local/smb4.conf. If you have time, also test with direct connection (NIC on workstation to NIC on FreeNAS server). Post full hardware specs on FreeNAS server as well (RAM, NICs, HBA / Raid Controller, etc).

It only affects the samba sessions, NFS continues working.

Nobody any idea ? :(
