Do you have a domain or workgroup ??

workgroup.
how can I find out what the dhcp range is, I did not set it up, it was done by my isp CD when they sent the adsl modem/router few weaks ago. now I am moving the internet access to another box "Linux" and want to change this w2k box to static ip.

when I look at the modem setup page using a browser, it says that the dhcp range is from 192.168.1.100 to ...149. well, is that set up in the PC or in the modem/router?

thanks

It certainly sounds like the IP is conflicting with the DHCP range.

I would either choose an IP outside the range, like 192.168.1.200. (or anything else between 1-99, 150-255).

Also your Default Gateway is wrong, (should be the router IP, which by default is 192.168.1.1). This is more likely your problem.

If you want 192.168.1.104 especially, and after setting your router IP correctly in default gateway, you are still unable to do so, then you could add it to the exclusion range for the DHCP, which you should be able to do on the router setup menu, under DHCP.

Also you need to add, an IP address for the DNS server, from your ISP. This can be found on the FAQ of your ISPs website I would expect, under instructions for configuring ADSL Modem / Routers. [Your DNS IP could be found in your Router no doubt, under DHCP settings, as it has to be there for it to work in the first place]

Any problems, get back to us.
