Removing Autodiscover Certificate

Evert time I boot up my PC (Vista) I keep getting a pop up telling me that Autodiscover has found a certificate and do I want to install it or continue without it, I have looked at the certificate and I don't recognise the domain although it thinks it is valid and I don't want to install it.

How can I stop this from happening as it's very annoying.

I should point out that my pc is part of a Domain

Hi Steveh24,

I have seen the attachment you sent and would like you to go through the below two links:

http://www.technoportal.com/2007/11/exchange-2007-autodiscover-problem.html



http://support.microsoft.com/kb/555842


This should be useful.

The fix I suggested should not prevent from finding valid certificate.


Regards,

Vishnu.

Hi Steveh24,

I understand that you are getting the error "Autodiscover has found a certificate " every time you boot the PC. Please follow the steps below:

Go to the client computer that has the issue and look in \windows\system32\drivers\etc and you will find a file named hosts.

1) Backup the file

2)Open with notepad

3) Add this entry at the bottom: 127.0.0.1 autodiscover.yourdomainnamehere.com - This way it will send the search right back to the client computer and no more error

4) Save the file and your done.

Please try these steps and let us know if it helped.

Regards,

Vishnu.

Hi Vishnu

Thanks for your response, it would appear that several people are now getting the error "Autodiscover has found a certificate " when they start up their PC's and I have attached a pdf of the offending security alert.

Would I need to try your solution on every PC or is this something to do with the Exchange Server

The problem now seems to occur everytime the Outlook client is opened, we use Exchange Server 2007
