To workaround this issue you’ll need to jump into the registry to enable Internet Connection Sharing (ICS). This is usually deployed via Group Policy on a domain network, so you may want to check with your network administrator first.
As usual, be careful editing the registry.
- Start > Run > gpedit.msc
- Navigate to Computer Configuration/Administrative Templates/Network/Network Connections
- Disable the following policies:
- Prohibit installation and configuration of Network Bridge on your DNS domain network
- Prohibit use of Internet Connection Firewall on your DNS domain network
- Prohibit use of Internet Connection Sharing on your DNS domain network
- Require domain users to elevate when setting a network’s location
- Start > Run > regedit
- Locate Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\Network Connections
- If this key doesn’t exist, it may be disabled by means other than group policy.
- Add/update a registry DWORD entry for the following, and set it to 1;
Thanks to Jeff for the find.
