I build systems in my condo. I use cox cable with motorola surfboard SB5100 & linksys WRT54G v3 wireless. I have one hardwired and one wireless. When I build new systems they are hard wired to the router after windows install. They obtain everything auto, ip, dns, dhcp etc. and connect to inet with no trouble. 1 in 6 systems will have a problem connecting to inet directly through modem or router/modem, once system is sold and moved to new location. All machines have onboard nic's 10/100 min. In order to access files I keep on my main machine, to complete installs, I setup a network using the network setup wizard naming the network SOCRATES. I also use on all machines: run/cmd/net user guest ******, to protect guest account access. With the troubled machine, when I run/cmd/ipconfig, everything shows up 0.0.0.0 I am un-able to ping anything, regardless of modem or router use. Normally I would log onto the router and DHCP release/renew but I'm not able to log on to the router, in this case a new D-link wireless 4 port switch. 2 other machines at this new location are able to us all three combinations; modem direct, or modem/router and wirleless to access inet. I'm not sure what I'm missing.....any ideas? Thank you!
