I'm running my G3 iMac OSX10.3.5 & a Win XP p.c. to an SMC router & a d-link dsl modem. As I'd had problems with the dsl dropping the connection, I up-dated its firmware recently -there were then problems with the mac reconnecting which drove me spare until everything 'magically' resolved when I simply logged out & back in again (!) -now, again, I can't make a network connection, even though the system preferences pane tells me I'm connected to the internet through the dsl, & dhcp gives correct addresses etc; I can access the internet & the mac from the pc -& if I restart in OS9 the mac's working- but when I restart in OSX I can't ping the router or see anything. I've repaired disc permissions, no change. Has anyone any ideas?

Duh... better keep the 'junior member' ticker there for a while... realised somehow that someway my Firewall had configured to block everything... I couldn't clear filters through Brickhouse or System Preferences, & I went to Brian Hill's (Brickhouse) site & found this wonderful information, in case it's of help to others:

"Make sure the /Library/StartupItems/Firewall folder is gone.

If it is, and you've rebooted, then there might be some other program/tool altering the firewall as well. Several of them do it, even though they aren't firewalls, per se.

Carrafix was/is one (deals with load limiting, I think). I think that the Mark/Space internet sharing for PDAs is another.

You can view what's ACTUALLY in your firewall using this command in Terminal:
sudo ipfw show

This will display all the currently installed filters no matter what program put them there.

You can also manually force the firewall to be cleared using this command:
sudo ipfw -f flush

However, if there is another startup item for another program installed that also alters the firewall, you may run into problems when you restart (such as the Mac OS X built-in firewall prefs getting ignored)."

-best of luck!
