there was/is a 3rd party firewall installed. this laptop has been used remotely through a connection with logmein, an online service where a friend helped with tech support. so i don't know what p/f sharing settings needed to be changed. windows firewall service is started. i still don't know how to see any wireless networks though, is there an add-on that would help me to see what is available?
it isn't installed at present, it is called ezfirewall, a toshiba product.
in windows firewall, advanced tab, i see 'the network settings have become corrupted. to fix this click restore defaults. this will delete all of your settings for windows firewall, and it might cause some programs to stop working.'
in exceptions i do not have p/f sharing checked, but have 2 'configfree summit engine' items checked, no check on uPnP framework. check on 'remote assistance' and 'microsoft management console'.
