Why am I having problems with my VPN connection?

If you can't connect via the Internet to your workplace network from home (or another location), check the items in this list:

  • Make sure that you typed the virtual private network (VPN) server name exactly as provided by your network administrator.

  • You must have an active Internet connection for a VPN connection to work.

  • If your modem is external, make sure that the modem power is turned on.

  • Contact your network administrator to make sure that you have the appropriate connection and domain permissions on the remote access server.

  • This could be a certificate problem. For assistance, contact your network administrator.

  • A VPN connection won't work with an active Winsock proxy client. Contact your network administrator to make sure the Winsock proxy client is not enabled.

  • If you know the IP address (for example: 131.107.10.25) of a website, type that address in the address bar of your web browser and press Enter. If this works, there is probably a Domain Name System (DNS) resolution problem. For assistance, contact your network administrator.

  • If you have special software that's required or installed by your workplace, it could be part of the problem. For assistance, contact your network administrator.

  • If you know the IP address (for example: 131.107.10.25) of your VPN server, type that address for the VPN connection, and then press Enter. If this works, there is probably a DNS resolution problem. For assistance, contact your network administrator.

  • There could be a problem with the server you're trying to connect to. For assistance, contact your network administrator.

If you try to connect with a VPN connection and you see a message that says "The local computer does not support encryption" and has the error code 741, it's possible that the encryption that your computer uses doesn't match the encryption used by the VPN server. To change the encryption settings so that your computer uses the recommended setting of 3DES, follow these steps:

  1. Open Connect to a Network by clicking the network icon (Picture of the wireless network icon or Picture of the wired network icon) in the notification area.

  2. Right-click the VPN connection, and then click Properties.

  3. Click the Security tab.

  4. Under Data encryption, select Maximum strength encryption (disconnect if server declines), and then click OK.

  5. Open Connect to a Network by clicking the network icon (Picture of the wireless network icon or Picture of the wired network icon) in the notification area.

  6. Click the VPN connection, and then click Connect to try connecting again.
