DHCP Server Failover and Load Balancing Configuration Notes (Consise)

Initial Server Scope Infrastructure:
- DC1 (Primary): Scopes corp net, corp net two, corp net three
- DC2 (Partner): Scope corp net
Identifying Failover Relationships in GUI:
- Not summarized in console main view.
- Active failover scope context menu displays Deconfigure failover.
- Scope Properties -> Failover tab displays partner server details (e.g., DC2 for corp net).
Wizard Initiation:
- Scope context menu: Limits configuration to selected scope.
- IPv4 container context menu: Allows selecting multiple scopes simultaneously.

Configuration Target: Scope corp net two on DC1 with partner DC2.
Wizard Options:
- Partner Server: Set to DC2.
- Reuse Existing Relationships: Uncheck to expose detailed setup parameters.
- Maximum Lead Time: Max duration partner extends lease issued by original server.
- Mode Selection: Load balance (Active/Active).
- Load Balance Split: Assigned $50\%$ to DC1 and $50\%$ to DC2.
- State Switchover Interval: Disabled in Load balance mode.
- Message Authentication: Uses shared secret key string for mutual server authentication.
Operational Mechanics:
- Replicates corp net two scope to DC2.
- Both servers actively issue pool addresses.
- Immediate lease state updates prevent duplicate IP allocation.

Administrative Access: Requires elevated PowerShell session.
