Guys , need to know about the Renewing SSL Certificates on Exchange Server 2007, as we have two CAS/HUB server ( Server1 & Server2) , so my doubt is when i have renewing the certificate on Server 1 then i do the same on server 2 as well or on one server (Renewing SSL Certificates on Exchange Server 2007) will be fine. As i am following the below steps for the renewal. If anybody knows any other way please let me know as well. Thanks. Create a certificate Send it to 3rd part root CA Once you will get the the new certificate save to C drive Remove the existing expired certificate Import the certificate what we received Enable the certificate what we received.

Need to know ... necessary to install the certificate on both the servers ( CASHUB1 and CASHUB2) or on only one of the server it's fine ....

If both servers are accepting traffic from the internet then both servers should have the certificate installed. Both servers should also be listed in the SSL certificate, so that one certificate covers both servers. You only do the certificate request and response on one server. Once complete simply export and import the certificate on to the second server and enable it. The process is identical to the first certificate, I have the full steps here: http://exchange.sembee.info/2007/install/multiplenamessl.asp Simon.Simon Butler, Exchange MVP Blog | Exchange Resources | In the UK?

Thanks Simon for your reply, i got your point as per you decent article but from the safer side i am just telling you the steps what i am going to perform you just please let me know if that is the correct way. One Server 1. 1. Once will get the the new certificate 2. Remove the existing expired certificate 3. Import the certificate what we received 4. Enable the certificate what we received. Now One Server 2 ( Will repeat the same steps) - correct ? Apart from this we need to import the certificates on the ISA server as well ! There also we need to import on both the server s CORRECT ? or only on one server, both the server are open for the connections ....

I can't answer questions about ISA, as I don't use that product. My article covers all of the steps. I wouldn't remove the old certificate until you have the new one in place though. Simon.Simon Butler, Exchange MVP Blog | Exchange Resources | In the UK? Hire Me.
