Network Access: setting Microsoft network server: Digitally sign communications (if client agrees) must be configured to Enabled

The server message block (SMB) protocol provides the basis for many network operations. Digitally signed SMB packets aid in preventing man-in-the-middle attacks. If this policy is enabled, the SMB server will negotiate SMB packet signing as requested by the client.

Remediation

To fix this configure the policy value for Computer Configuration >> Windows Settings >> Security Settings >> Local Policies >> Security Options >> "Microsoft network server: Digitally sign communications (if client agrees)" to "Enabled".
