Hi LisaFigueiredo,
Do you need to use a proxy server?
If you don't, you can disable this by following the below steps:
- Open the Windows start menu
- Search for 'Internet Options'
- Open Internet Options
- Select the Connections tab
- Select LAN settings (at the bottom of the window)
- Untick the three tick boxes ('Automatically detect settings', 'Use automatic configuration script', and 'Use a proxy server for your LAN (These settings will nto apply to dial-up or VPN connections)')
Hope this helps,
Nathan
