Hi guys, I'm a newbie here. 10+ year SW developer. I just started my own business and have about 7 computers. I have a DSL modem that connects to a Siemens router, then to a Netgear switch. All the computers are connected to the Netgear swtch. Everything works fantastic, with one exception. When I boot up any one of the computers, it gets assigned an IP of 192.168.0.x and will not connect to the internet. I have to do ipconfig /release then ipconfig /renew to get an IP with 254 instead of zero in the third position (192.168.254.x), and then everything's fine. One machine has 2000 Server, the rest are XP Pro. Any advice on how to resolve this? Thanks in advance!!! gltech
