Programs like mobile phone connection optimizer software may install the Winsock Base Service Provider (BSP). BSPs sometimes bypass the Firewall client. To raise an alarm about the situation, ISA Firewall client displays one of those ugly yellow exclamation marks on the system tray icon. If you hover your mouse over it, it shouts “Firewall client is not installed properly”. An example of software that causes this condition is AT&T Comms Manager.
If this is too annoying for you, you can get rid of the warning:
- Download and Install the hotfix
- Open REGEDIT, find the key “HKEY_LOCAL_MACHINESOFTWAREMicrosoftFirewall Client 2004Policies” and add a new “DWORD” value “UiEnableCatalogValidation” and set it to “0″ (zero).
