RESOLUTION

Verify your Internet Explorer connection settings
Note Before you continue, remove or turn off any firewall, internet security, or proxy software that is installed.
To verify that you can connect to your Internet service provider (ISP) and that the connection settings for Internet Explorer are correct, follow these steps:
1. Verify that the Use a Proxy Server check box is cleared or selected, according to your Network Administrator or ISP's instructions. To view this check box, follow these steps:
a. Start Internet Explorer.
b. Click Tools, and then click Internet Options.
c. Use one of the following methods:
• For LAN and most DSL and Cable modem users, click the Connections tab, and then click LAN Settings.
• For dialup modem and Point-to-Point Protocol over Ethernet (PPPoE) users, click the Connections tab, click the appropriate connection under Dial-up and Virtual Private Network settings, and then click Settings
2. Use an ISP access number that is not a toll number.

Look for Hosts files

1. Click Start, point to Search, and then click For Files or Folders.
2. In the All or part of the file name box, type hosts.
3. In the Look in list, click your hard disk, and then click Search.
4. Click all the Hosts files that are found. If there is more than one, click one Hosts file, and then hold down the CTRL key while you click other Hosts files.
5. Press F2.
6. Type a new name. For example, type oldhosts, and then press ENTER.
