In XP, webpages would not load in IE. IPCONFIG and PING both would hang indefinitely.
I dropped the norton firewall. Now all was OK. Webpages loaded, and IPCONFIG + PING worked.
The norton firewall had been customized (probably in error, user is newbie). So I set it back to default firewall settings, and turned the firewall back on.
Now webpages loaded fine in IE. But IPCONFIG and PING still hung.
I tried "allowing" the PING and IPCONFIG executables in the firewall program list, but this didn't seem to help.
So in interests of saving him money, we uninstalled NOrton Internet Security, and are now using the windows firewall and another antivirus he has.
For my education -- what would cause this behavior in a 3rd-party firewall?
(would I have to allow a certain IP, beyond the range that covers my local network / adapers? Does ping and/or ipconfig use an "ip"? the local network was 192.168.1.1 / 100, and 192.168.1.0 was allowed by network wizzard)
