I have a single computer on a 2Wire 1800HG DSL gateway, no other computers connected to the gateway. The computer has two network connections -- Ethernet (DSL) and Dialup. I recently upgraded from SP1 to SP2 for Windows XP Home. The computer was free of viruses (per CA and NAV scans) and spyware/malware (per Ad-aware scans) before the upgrade and it remains that way.
My intention was to have Windows Firewall enabled for the rarely-used Dialup connection but disabled for the DSL connection, relying on the hardware firewall in my DSL gateway for the DSL connection. That is the way I had XP SP1 configured and it appeared to do what I expected.
With Windows Firewall ON but with network connections enabled/disabled as described above, now I get popups saying two programs (hpstatus and javaw) have been blocked during startup. Both seem harmless. The same thing happens even if I disable the firewall for both network connections. If I run hpstatus.exe after (instead of during) startup, it is blocked even if I run it after getting the nag balloon about the firewall being OFF.
The only way to avoid blocking is to turn OFF the Windows Firewall, which was not my intention.
Is this the way Windows Firewall is supposed to work? I have never seen it described as working this way.
