SSPI handshake failed with error code 0x80090311

- ACEPDC7 is DHCP assigned which is a no-no for a domain controller. After assigning a static address I'd do ipconfig /flushdns, ipconfig /registerdns, restart the netlogon service.

- ACEPDC4 is DHCP assigned which is a no-no for a domain controller. After assigning a static address I'd do ipconfig /flushdns, ipconfig /registerdns, restart the netlogon service.

- ACEPDC5 -> ACEPDC4 5012 errors

- ACEPDC6 event logs cannot be queried because of RPC, so I'd check the logs for possible errors

- ACEPDC7 event logs cannot be queried because of RPC, so I'd check the logs for possible errors

- ACEPDC4 has replication problems. I'd check the event logs for error details (may be related to DHCP assignment)
