  2. SMBv1 named pipe requests do not time out when the remote server hangs in Windows 7, Windows Server 2008, Windows 8.1, and Windows Server 2012 R2

SMBv1 named pipe requests do not time out when the remote server hangs in Windows 7, Windows Server 2008, Windows 8.1, and Windows Server 2012 R2

View products that this article applies to.

Symptoms

Assume that a Windows 7, Windows Server 2008, Windows 8.1 or Windows Server 2012 R2-based computer sends SMBv1 named pipe requests to a remote server. When the remote server hangs, the request does not time out as expected. Therefore, the applications that use the named pipe hang indefinitely.
