I have a backup of previous and expired certificate.

What happens when clients try to connect - any error messages?  Does anything get logged in the event log when they try to connect?

 

by: Rod_UKPosted on 2009-10-11 at 05:30:23ID: 25545703

from firefox:

An error occurred during a connection to server1.

Certificate type not approved for application.

(Error code: sec_error_inadequate_cert_type)

The page you are trying to view can not be shown because the authenticity of the received data could not be verified.

Please contact the web site owners to inform them of this problem. Alternatively, use the command found in the help menu to report this broken site.


from IE:  

certificate warning, There is a problem with this website's security certificate
I if choose: Continue to this website (not recommended).   I received the error below:

This problem can be caused by a variety of issues, including:

"Internet connectivity has been lost.
"The website is temporarily unavailable.
"The Domain Name Server (DNS) is not reachable.
"The Domain Name Server (DNS) does not have a listing for the website's domain.
"There might be a typing error in the address.
"If this is an HTTPS (secure) address, click Tools, click Internet Options, click Advanced, and check to be sure the SSL and TLS protocols are enabled under the security section.

I have also tested from server only with IE, same problem.

Click view certificate in IIS - what is the Template and Enhanced Key Usage listed as under details?

Also, have you tried restarting the IIS services?

 

by: Rod_UKPosted on 2009-10-11 at 07:02:15ID: 25545930

Thanks -DJL-:

Certificate Template Name: Administrator
Enhanced Key Usage:
MS Trust List Signing
Encryting File System
Secure Email
Client Authentication

do you need all version numbers?

 

by: Rod_UKPosted on 2009-10-11 at 07:02:45ID: 25545934

Yes I restarted IIS services several time.

 

by: -DJL-Posted on 2009-10-11 at 07:13:15ID: 25545968

The certificate is the wrong type.  You need "Server Authentication" listed in Key Usage field.

run MMC and add the Certificates snapin for the local computer.  Under personal, certificates try and request a new computer certificate.  

If you successfully get issued another certificate and Server Authentication is listed under Intended purposes, you can then go back into IIS Manager and replace the certificate with the one you have just requested.

 

by: Rod_UKPosted on 2009-10-11 at 07:55:34ID: 25546117

I exported certificated sucessfully.

now back on IIS, do I need to remove or replace the current cerficate?

Thanks

 

by: -DJL-Posted on 2009-10-11 at 07:57:22ID: 25546122

replace - then select the new certificate you requested.

Spotted on!

I can now have access to OWA

Many thanks
