| - | ====== Troubleshooting VPN Connection Problems ====== | ||
| - | |||
| - | There are many types of Internet Service Providers (ISP) and routers available, and it is difficult to know the exact details on how they work in random combinations. | ||
| - | |||
| - | |||
| - | * Some ISP's have certain guidelines to physically connect to their network (registered MAC addresses, software authentication clients…etc), or simply do not allow VPN traffic/connections to be made over their network. | ||
| - | |||
| - | ====== Getting Started ====== | ||
| - | |||
| - | |||
| - | * Open a command prompt to clear cached Olin network information from your computer. | ||
| - | * Go to: | ||
| - | * **START→Run** (OR:**Windows Key + R**)→''CMD'' (command prompt) | ||
| - | * Enter ''ipconfig /flushdns'' | ||
| - | * Open a command prompt and see if you can communicate with the Olin VPN server… | ||
| - | * Go to: | ||

| - | |||
| - | * This is what a successful ping attempt to the Olin VPN server will look like. | ||
| - | - If the ping attempt did not go through correctly and you use a router, please retry without the router installed in the network. | ||
| - | - If you are still unsuccessful, please send an email to the Help Desk with the following information | ||
| - | - Are you using the correct VPN login and password? | ||
| - | * The VPN software does require a username and password. | ||
| - | * This is not your network username and password. | ||
| - | * You can send a request to [[helpdesk@olin.edu|helpdesk@olin.edu]] to create a VPN account or to reset your password | ||
| - | - Who is your ISP? | ||
| - | - Is your ISP dial-up, cable modem, or DSL? | ||
