Autodiscover issues on Exchange 2010

Hi,

We are getting this message now when user opens Outlook 2007 on their PC - "The name of the security certificate is invalid or does not match the name of the site"

Is there a way to get rid of this without having to replace the certificate or some sort?

Cheers,
Goraek

Is the certificate valid?

goraekAuthor Commented:
Yes, it is valid. There have 2 domains - domain.com and domain1.com. We have a certificate for domain.com but not domain1.com.

Hence, when we opened Outlook 2007, it is showing autodiscover.domain1.com.

Is there a way to get rid of this and revert back to normal settings?

in dns the settings for autodiscover are valid?

goraekAuthor Commented:
Microsoft DNS? Yes it is.
However we deleted domain1.com as domain.com is primary. At the moment, the security is showing autodiscover.domain1.com - we need to get rid of this.
