Windows 7 Internet Connection Sharing: No Internet Access

[alberto]

Sorry, yes, can you please check on the laptop if the Internet Connection Sharing service is running properly?

 

[Ben Hutchinson]

it appears to be working in the services page thingy, i tried restarting it, still no ICS

 

[alberto]

Great... How about the Event Viewer on the laptop? Anything relevant there?

 

[Ben Hutchinson]

Error: The ICS_IPV6 failed to configure IPv6 stack.

 

[alberto]

Ah, wonderful, an error! Try disabling IPv6.
How to disable IP version 6 (IPv6) or its specific components in Windows 7, in Windows Vista, in Windows Server 2008 R2, and in Windows Server 2008

 

[Ben Hutchinson]

still nothing

 

[alberto]

What does the event viewer say?

 

[Ben Hutchinson]

3 separate errors:

1: The DHCP allocator has detected a DHCP server with IP address 10.0.0.138 on the same network as the interface with IP address 192.168.137.1. The allocator has disabled itself on the interface to avoid confusing DHCP clients.

2. The DNS proxy agent was unable to allocate 0 bytes of memory. This may indicate that the system is low on virtual memory, or that the memory manager has encountered an internal error.

3. The DHCP allocator has disabled itself on IP address 10.0.0.9, since the IP address is outside the 192.168.137.0/255.255.255.0 scope from which addresses are being allocated to DHCP clients. To enable the DHCP allocator on this IP address, change the scope to include the IP address, or change the IP address to fall within the scope.

And this is on the laptop, right?

 

[Ben Hutchinson]

ya, those were the only error messages on laptop from recent

 

[alberto]

OK, so try setting the IP address for the laptop's ethernet to 192.168.137.100 and the host PC's ethernet card to 192.168.137.101, with the host pc's DNS and gateway set to 192.168.137.100

 

[Ben Hutchinson]

no internet access still, but the laptop and the pc can ping each other, no error messages

 

[alberto]

No error messages in the event viewer?
Can you ping 10.0.0.138 from the host PC?

 

[Ben Hutchinson]

ping request timed out

 

[alberto]

I am very sorry but right now I'm stumped. Networking between the 2 PCs seems to be up and running, you can ping each machine from the other, ICS service on the server seems to be running, no error logs on event viewer. I'm truly at a loss for ideas. Let's hope someone else comes along with a better understanding of networking than I have. I'm really sorry.

thanks for ur help, even though the internet isn't working you've helped me learn abit about how to troubleshoot these things by myself, ima try some more things then probably give up and go buy a wireless card, xD
