Is your request related to a problem? Please describe.
Healthchecker should check if IIS bindings are correctly configured, especially on the backend website.
Binding should be "all unassigned" and not for a specific IP address.

Describe The Request
The correct default values on backend should be like this:
Exchange Back End Started False http - *:81: - NULL
https - *:444: - 69DE5CA602D04D03939DA4E2F5BE2D076609B906
Incorrect setting on backend:
Exchange Back End Started False http - *:81: - NULL
https - 192.168.10.48:444: - 69DE5CA602D04D03939DA4E2F5BE2D076609B906

This becomes important when extended protection is enabled. When it is, and the binding is set to a specific IP address of the server the backend will drop the connection with the well known SEC_E_BAD_BNDINGS error; 2148074310.

Additional context
Checked with Exchange Health Checker version 24.10.15.1910
