Dear Experts,

I have just purchased a new cert and want to install it into my EBS environment. Previously we had domainA.com and now we will be using domainB.com.  So we still need domainA.com to feature in our organisation for a year (or so).

So I purchased a UC cert from comodo for the fqdn remote.domainA.com and remote.domainB.com. I have completed the cert request in IIS7 on the management server. I exported it and added to the trusted root authority and personal store on the security server (forefront) then added it to  listener in the rww publishing rule within forefront.

I have made all the necessary DNS changes for MX and A records for the domainB.com

In exchange, I have added domainB.com to the list of accepted domains and changed the recipient policy to make it the default for sending for all users.  I have tested mailflow to and from user@domainB.com and all seems ok.

2 questions:

1. Given the information above, I can still access the rww site by visitng https://remote.domainA.com and all works fine. When I view the certificate presented, it shows me the new one. But when I visit https://remote.domainB.com i get the "The page cannot be displayed " with "Error Code: 403 Forbidden. The server denied the specified Uniform Resource Locator (URL). Contact the server administrator. (12202)"

What gives here?

2. What else have I missed? I'm pretty sure that I have to update and enable the exchange  certificate services.

Bear in mind I have no experience with UC certificates and am treading carefully here...

Many thanks in advance.

you need to install the new certificate onto the exchange server
then run the following to locate the cert
get-exchangecertificate | fl

then using the thumbprint for the new cert run
enable-exchangecertificate -thumbprint <id> -services "iis,pop,imap,smtp"

you do not need to restart any services

Ok. great.  Will that sort the problem of accessing RWW using the https://remote.domainB.com ?

the error displayed in IE8 is:

The page cannot be displayed  
Explanation: There is a problem with the page you are trying to reach and it cannot be displayed.

--------------------------------------------------------------------------------

Try the following:

Refresh page: Search for the page again by clicking the Refresh button. The timeout may have occurred due to Internet congestion.
Check spelling: Check that you typed the Web page address correctly. The address may have been mistyped.
Access from a link: If there is a link to the page you are looking for, try accessing the page from that link.

I installed the new cert on the exchange server. I ran the enable-exchangecertificate -thumbprint <id> -services "iis,pop,imap,smtp"  command  and all users immediatley received a certificate error message.  So I switched it back.

Any thoughts.

I have looked at the forefront logs and found the following entry. I have changed the private names and addresses where applicable:

It would appear that ISA is denying access when the name remote.domainB.com is used by the client.

Any further thoughts?

When you set up the publishing rule on your ISA, did you import the private key with the certificates?

I believe so.  I exported the cert from the management server and imported it into ISA. Then i added it to the listener.
