<p class="MsoNormal">“<WBN>>: Section 3.3.5.2.9: When Session.State is Expired, Windows Vista, Windows Server 2008, Windows 7 and Windows Server 2008 R2 servers do not fail the request in the following cases: If the SMB2 header of the request has SMB2_FLAGS_SIGNED
set in the Flags field, and the request is not an SMB2 LOCK request as specified in section 2.2.26.”<o:p></o:p></p>

<p class="MsoNormal"><span style="color:#1F497D">I look into the code and it looks like before allowing any operation, server does validate the session (which includes checking for expiration). Can you please send a network traces to show this?<o:p></o:p></span></p>
