OWA does not work on Windows 7

Dear Experts

we have OWA for our exchange server 2003 it does not work only on Windows 7 machine get the following error.

The page requires a client certificate
The page you are attempting to access requires your browser to have a Secure Sockets Layer (SSL) client certificate that the Web server will recognize. The client certificate is used for identifying you as a valid user of the resource.

Please try the following:

•Contact the Web site administrator if you believe you should be able to view this directory or page without a client certificate, or to obtain a client certificate.
•If you already have a client certificate, use your Web browser's security features to ensure that your client certificate is installed properly. (Some Web browsers refer to client certificates as browser or personal certificates.)
HTTP Error 403.7 - Forbidden: SSL client certificate is required.
Internet Information Services (IIS)


Technical Information (for support personnel)

•Go to Microsoft Product Support Services and perform a title search for the words HTTP and 403.
•Open IIS Help, which is accessible in IIS Manager (inetmgr), and search for topics titled About Certificates, Using Certificate Trust Lists, Enabling Client Certificates, and About Custom Error Messages.

pls suggest

I would guess that the problem is caused by using a self signed cert. You need to import the certificate to the users machine, and add it to the trusted root.

You could try using something like this to check the certificate - http://www.digicert.com/help/ 

I've also noticed a strange phenonium... the very first time I connect to my OWA on a Win7 system, there is a significant delay before I get prompted for my credentials (we use Smart Card authentication).   Sometime it takes up to a minute!   But, after than... any subsequent connection works like a charm.
