A Remote Desktop session may stop responding when you access a remote shared folder by using SMB version 2

Symptoms

Consider the following scenario:
  • You have a server that is running Windows Server 2008 R2 Service Pack 1.
  • You start a Remote Desktop session from a client computer to the server.
  • Then, you access a remote shared folder by using the Server Message Block (SMB) version 2 protocol from the Remote Desktop session.

In this scenario, if the network between the server and the remote share is not stable, the Remote Desktop session may randomly stop responding.

Note This problem may also randomly occur when you access a file share by using SMB version 2 over a high latency network.

Cause

This problem occurs because the SMB version 2 disconnect is handled incorrectly.
