I have an LG Ultimate 2 an it just keeps flashing on an off saying, error : boot certification verify secure booting error, cause : boot certification verify. How do I fix that?


This requires more technical in person diagnosis. some things you can try are to boot in to the bios menu.
  • To do this you will have to watch as it is turning on and on one of the startup screens it will tell you to press one of the function keys (F10, F2,F12, and so on) click the one that says "bios" or "settings".
  • After that you will need to search through all the settings for something called the "IDE self test" run that once, it will take a while.
  • and lastly look for another option called the boot order. you have to make sure that the option that says hard drive is first.
I am sorry i can't be of more assistance but not much can be done without seeing the laptop.

Aastra voicemail


This Depends on your providers system . If yo go and retrieve your messages and hit 4 3 2 2 this will get you to nowhere you can record a message for incoming calls. If you want to change you message for when some calls you and you are on the phone you would do the same as above but hit 4 3 2 1. That is where you change your "on the phone message" never put a date in that one. Just record " hi I am on the phone at the moment please lease a message at the tone" Hope this helps

Activate message indicator light on


Call your provider and ask them to turn it on. They probably forgotto include that. If you pick up and there is a repetitive busy sound the company has you set for sadder. Tell them you have an indicator light hope this helps

I have a aastra 390 phone, the message light keeps flashing when no messages


You have unheard messages on the voicemail system provided by your telephone company. This system records messages when someone calls while you're already on the phone. Please contact your telephone company for instructions on accessing their voicemail system.

I am having problems connecting VPN Connection on my Windows 7, it says there need to be a machine certificate installed before i can connect using L2TP/IPsec. error code :766


"Error 766: A certificate could not be found. Connections that use the L2TP protocol over IPSec require the installation of a machine certificate, also known as a computer certificate."

"Error 766: The L2TP connection attempt failed because the security layer could not authenticate the remote computer."

Cause: Connections that use the L2TP protocol over IPSec require the installation of a machine certificate, also known as a computer certificate. You will see this error message when such a certificate is not available.

Typically, this error is generated on a remote access server that has active L2TP ports configured, the remote access service started but there is no certificate in the computer certificate store. This generates an event log message that tells the administrator that L2TP ports will not be able to accept calls until a certificate is acquired and RRAS is restarted.
Resolutions: 1. If you use PPTP VPN, select Automatic in Type of VPN.
2. If you use L2TP, check the remote access server and make sure there is certificate in the computer certificate store.
