In response to CVE-2022-38023, Microsoft is removing support for RPC Signing in the Netlogon server, instead requiring Sealing when establishing a 'secure channel'. More details can be found here: https://support.microsoft.com/en-us/topic/kb5021130-how-to-manage-the-netlogon-protocol-changes-related-to-cve-2022-38023-46ea3067-3989-4d40-963c-680fd9e8ee25 and here: https://msrc.microsoft.com/update-guide/vulnerability/CVE-2022-38023

The previous changes in response to Zerologon mitigations (#13169) implemented RPC Signing in the netlogon client to satisfy the RPC security requirement; now we must implement Sealing to continue to support NTLMSSP authentication in the SMB Server, building off that prior work.
