WIN11-01's vmx is encrypted and its NIC is bridged to the physical LAN
|
||||
(192.168.1.132), so it currently can't reach DC01 (192.168.31.10). Fix is a

VMware-side NIC change plus a <code>Test-ComputerSecureChannel -Repair</code>.
|
||||
Documented honestly rather than papered over.
|

WIN11-01's NIC was moved from a bridged physical-LAN adapter to the lab
|
||||
NAT network, DNS was pointed at DC01, and the machine account trust was
|

repaired. Verified domain authentication and DC discovery:
