I have been banging my head against a wall here.. Last night I was up until 4 am trying to setup an ICS so I could share my internet from my laptop's wifi to my desktop PC via an Ethernet cable. I have spent the entire morning trying some new things after a fresh nights sleep, but I keep getting issues and no solution.

What I have done so far:
I have made sure that ICS is enabled on both PC's
All dependent services for ICS are enabled
Firewall enabled
flashed BIOS
Reinstalled ethernet driver
Reset IPV4/6
set both IPV4/6 to auto IP and DNS
Removed adware and malware

When I attempted to share my main wireless Wifi connection and allow ICS to share it with the ethernet I got "An error occurred when enabling internet connection sharing. (null)"

Google results said to enable all dependent services, and then firewall, which I did, but I still got the error and could not share my connection.

I tried to bypass or try another solution so I tried to bridge the two connections, but I got another message, not necessarily an error: "To create a Network Bridge, you must select at least two LAN or High-Speed Internet connections, that are not being used by Internet Connection Sharing."

I am not sharing my connection and I don't believe ICS is actually being used so this really confuses me. I even disabled ICS and tried to bridge the connections, but I received the same message.

Originally I had tried to troubleshoot the ethernet connection via Windows troubleshooter and it told me that the connection has an invalid IP configuration.

The network shows up as a public "Unidentified Network". I am able to see both computers and share files, but I have no access to internet.


Any help would be appreciated. I am at a loss.

"I have made sure that ICS is enabled on both PC's"


Only do the pc with internet access


Make sure the firewall allows ICS.  Post the results of a ipconfig /all  [note the all] from a command prompt and post the results for review.  This is only from the machine hosting the internet via ics which you mention as the laptop.
