The Netlogon Remote Protocol remote procedure call (RPC) interface is primarily used to maintain the relationship between a device and its domain, and relationships among domain controllers (DCs) and domains.
What will change?
On Thursday July 20th between 6:00 p.m. and 8:00 p.m., the central domain controllers servicing Active Directory DS/LDAPS will be patched to complete the final rollout. Vulnerable connections from non-compliant devices will be blocked.
We thank you for your time and continued understanding.
