Today I opened my settings window to temporarily set "Block All Network Traffic" and found all buttons and "Configure [+]" links greyed out and deactivated for Intrusion Prevention and Smart Firewall. Same is true if I right click on the quick start icon. The pop up menu has the "Disable Smart Firewall" greyed out and deactivated.
This must have occurred after a recent live update. Cannot enable or disable Smart Firewall or re-configure the above mentioned. Running NIS on Windows XP. Is there a fix for this.
