DataCore Server Settings Disclosure

To allow DataCore SANsymphony to function properly, certain Windows operating system and firewall settings are altered during installation, and upgrades. Security settings are changed but never disabled.

Firewall rules are added to allow the DataCore Executive Service to communicate with all other DataCore Servers on the network and to allow any iSCSI connections to take place.

All firewall rules can be viewed in Server Manager>Local Server>Windows Firewall.
