SSL Certificate renewal not working on Exchange 2003

Hi Experts!

We've got a customer with an SSL certificate that expired and we tried to renew it.  Everything works with the CSR request, but when we get the certificate back via email from our SSL provider, it won't import the certificate.  Currently, I've manually imported the certificate (using the certificates add-in in MMC) and have attached the proper certificate (meaning it has the new expiration date) to the Default Website (the one that contains /exchange).  However, it's not working.  Anyone have some ideas I can try?  I've disabled the "default" Rapid SSL certificate and imported the certificate authority that they sent.  We're stuck and the customer can't get email via smart phones or web.

Thanks!

I would go back to the SSL provider and ask if you can get the SSL certificate reissued from a new CSR. Then generate a new CSR in IIS manager and send it to them.

It isn't unusual for CSRs to get corrupt at either stage - I remember once having to do it five times because the firewall was corrupting it!

I've even tried deleting the certificate and going through the entire process (by creating a new certificate request in directory security).  But it refuses to import the .cer file I create and talks about private keys (sorry I don't have the exact error message)...

Here's the exact error message when I try to import the .cer file:

The pending certificate request for this response file was not found.  This request may be canceled.  You cannot install selected response certificate using this Wizard.

I got a new SSL certificate (a wildcard this time) from our provider and went through the entire process and it worked.  But, I can't access my website.  It's not giving me any errors or anything, even local https://servername doesn't work.  I'm lost.

Check in IIS manager that you have the correct bindings. You should have two - 80 and 443.

Simon,

Thanks for the help.  Ended up doing the new certificate and it worked, but I had followed some instructions elsewhere on EE about doing the certificate renewal with a temporary website.  IIS had started the temp website instead of "Default Website".  Once I deleted the temporary one, all is well.  Still would have liked to figure out the corruption of the old one, but completely new SSL certificate wins.  Thanks!
