I'm setting up an HP All-In-One Photosmart 3210 printer on a network in a small office. Three PCs are able to see and use the printer just fine. The fourth PC is not able to install it, because the installation can't see the printer on the network. (All four computers are running fully-patched Windows XP Professional SP2.)
When I try to install the printer on this PC, I get an "Issues Stopping Installation" dialog which lists four issues: "Symantec Settings Manager: Firewall", "Symantec Network Drivers Service: Firewall", "Symantec Event Manager: Firewall", and "Symantec Core LC: Firewall". The description for all four tells me that I have firewall software on my computer that I need to disable before the installation will be able to detect the printer.
Problem is, I don't *have* a firewall on this computer. The only Symantec software I have installed is Norton Antivirus 2006, and that doesn't come with a firewall. Norton Protection Center doesn't list a firewall as being available. The built-in Windows Firewall is turned off; even if I turn it on, there's no other firewall that complains about any conflict. I see no processes or services running that would seem to indicate any kind of a firewall.
The printer is being assigned an IP address on the network. I can ping that IP address from this computer, but when I point the HP printer installation at that address for the printer, it can't see anything.
How do I figure out what firewall the HP installer thinks is interfering with setting up the printer?
