DHCP Problems

Girdag · 23 Apr 2007 at 09:20

Right. My home PC connects to the net using a powerline network, which connects it to my parents' PC, downstairs. Then the net connection is shared between the two (we have a USB modem, so that's the only way we can do it). Anyway, yesterday afternoon, it went down. I can access the network on my PC upstairs, but not the internet. Apparently my mother had reset the PC downstairs because of 'some problems'. Great.

Investigating on my parent's PC turned up that it's failing to be given an IP address by the network, and attempts to release/renew the IP address using ipconfig have turned up problems with the DHCP server. So, is there an easy fix to get this working again (I tried WinSockFix, no effect), or is there a way to get the network going using static IPs? I can still access the internet on the PC downstairs, just need to get the network working.

Thanks for any replies.

Is ICS enabled?
Control Panel -> Network Connections -> Internet connection -> Properties and one of the tabs there has a sharing option.

Yes, it is.

Try disabling and reenabling it? Any firewalls (tried disabling them?)?
What does start, run, cmd, ipconfig /all say for both machines?

I can't imagine it working, but if you want to try statically assigned IPs, set the host machine to 192.168.0.1, subnet mask 255.255.255.0, and the client to 192.168.0.x (where 1<x<255), subnet mask 255.255.255.0, default gateway 192.168.0.1. DNS server 192.168.0.1 on the client should work, though you might be better inserting the ISP's DNS servers.

Tried disabling and re-enabling it, and disabling firewalls, neither worked. I'll give the static IPs a go.
