AlwaysOnSetup changelog

Fix: SA-rename issue in endpoint and job creation

Path convention change

Replaced C:\Temp paths with C:\System in certificate and backup handling.

Fix: manual entry when no cluster role is found

ListenerName/AGName must be entered manually if no cluster role can be detected.

Added Reset button and IP validation

Added German/English bilingual support

Fix: secondary-replica failover mode

Now set explicitly via MODIFY REPLICA instead of relying on a default.

Cross-domain login and certificate handling

Robust Step 4 cross-domain login with certificate fallback; UPN conversion now uses the target domain's NetBIOS name; UPN fallback for cross-domain CREATE LOGIN; hadr enabled fix split into two separate sp_configure calls (required for it to take effect reliably).

Added Step 8 — AG-sync job on all nodes

Added Start-AlwaysOnSetup.cmd + AlwaysOnSetup.ini

Fixed shortly after: the starter now copies itself locally before elevation, and the GUI's SplitterDistance is set correctly on startup.

Initial release

AlwaysOn Availability Group setup automation, MIT-licensed. Auto-enables Mixed Mode when SPNs are missing; fixed the backup path to use a local path instead of UNC. Added a 15-slide bilingual (DE/EN) Reveal.js presentation with a full WinForms GUI mockup matching the website, including documentation of the endpoint-ownership problem.
