WN12-SO-000029 - The Windows SMB client must be enabled to perform SMB packet signing when possible.

Information

The server message block (SMB) protocol provides the basis for many network operations. If this policy is enabled, the SMB client will request packet signing when communicating with an SMB server that is enabled or required to perform SMB packet signing.

Solution

Configure the policy value for Computer Configuration -> Windows Settings -> Security Settings -> Local Policies -> Security Options -> 'Microsoft network client: Digitally sign communications (if server agrees)' to 'Enabled'.
