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

[Francesco_Beccari]

Hello,

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 ?

Hello,

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?
