Hello,

(First post from new member)

I have a a Motorola SB4100 cable modem which connects to internet fine with both an XP desktop and my company Vista laptop.

I am trying to connect another laptop (Dell XP SP3) and having no joy. Just getting the "cannot connect to DHCP server" message. There is no network setup, just connecting each machine separately.

I have tried the usual stuff; repowering everything, replace cables, ipconfig /release /renew etc.

If I set up a static IP address of 192.168.100.2 I can browse to the modem on 192.168.100.1; so I know I am connected OK. Once I go back to auto IP, I just get the no DHCP again.

There are 2 possibly relevant factors:

This laptop was previously working on a wireless connection successfully and I can see it is looking for a wireless connection on boot up.

The laptop was previously on a company network domain; could that be a problem?

I have now reached the limit of my knowledge and could use some help.

TIA

Andrew
