Hi Metze:
Thank you for pointing out this behavior of Windows 2008 R2. In a future release of \
MS-SMB2, section “3.3.5.2.9 Verifying the Session” will be modified as follows:
Existing text
=========
“…
If a session is found and Session.State is set to Expired, the server MUST fail the \
request with STATUS_NETWORK_SESSION_EXPIRED…. “
New text
=======
“…
If a session is found and Session.State is set to Expired, the server SHOULD <WBN> \
fail the request with STATUS_NETWORK_SESSION_EXPIRED… “
“<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.”
Please let me know if it does not answer your question.
Regards,
Obaid Farooqi

expired sessions
Hi Metze:
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?
