Single Answer, Multiple Choice

 

When you connect to another network using a PPTP virtual private network (VPN) connection on your Windows Vista Home Basic computer, you receive an error code 741 with a message that says, “The local computer does not support encryption.”

 

What might be the possible cause?

 

 

  1. Windows Vista Home Basic Edition cannot connect to other network using VPN connection.
  2. The encryption attempt failed because no valid certificate was found.
  3. Windows Defender is blocking the protocols required for the VPN connection.
  4. The encryption on your computer does not match the encryption used by the VPN server.

 

Answer:
D. The encryption on your computer does not match the encryption used by the VPN server.

 

Tutorial:
The option stating “The encryption on your computer does not match the encryption used by the VPN server” is the cause of the problem. To change the encryption settings for the VPN connection, you should click Connect to a network link in the Network and Sharing Center window in the Control Panel to open the VPN connection properties. In the properties window, you need to click the Security tab, click Advanced (custom settings) and then click Settings to open the Advanced Security Settings dialogue box. You should select the proper encryption algorithm (the one used on the server) under Data encryption in the Advanced Security Settings dialogue box and then try connecting again.

 

The option stating “Windows Vista Home Basic Edition cannot connect to other networks using a VPN connection” is incorrect. You can access remote computers and devices on a private network using a dial-up or VPN connection from any edition of Windows Vista computer.

 

The option stating “The encryption attempt failed because no valid certificate was found” is incorrect because a PPTP VPN connection does not need a certificate. And in this scenario, you are using a PPTP VPN connection on your Windows Vista Home Basic computer to connect to another network.

 

The option stating “Windows defender is blocking the protocols required for the VPN connection” is incorrect. Windows Defender is an anti-spyware program — it does not act as a firewall.
