SMB connections interrupted - events 30805,30807,30806,30808

Copper Contributor



all my Remote Desktop servers (Windows Server 2016) periodically report events SMBClient 30805 and 30807. Upon these events, SMB stops working (cannot reach any SMB share by hostname, IP address; even by command prompt, the net use \\hostname shows a blinking cursor and no result). Servers are reacheable on the network (I can PING them).


The problem solves with no intervention after a variable amount of time (one to ten minutes): events SMBClient 30806 and 30808 appear in the Event Viewer.


Thanks in advance to anyone!

Hello @Francesco_Beccari,


It only happen to your RDS server ?

That’s your users using the RDS that report the issue ?








thank you for your interest.

The problem seems to be related to the Windows Firewall.

I actually disabled Windows Firewall, now I'm testing if the problem solved.

Creating a "allowed by default" in/out policy actually did not help.


Hope this solves :)




Did your solution "Creating a "allowed by default" in/out policy actually did not help." work?
