Need to replace self issued certificate with 3rd party certificate - questions

Hello,

When we were poor and cheap we created a self issued security certificate for SSL access to our OWA site.  It is now time to replace that certificate with a 3rd party certificate.  However, I no longer see the options to create the CSR to request the certificate.  Do I need to delete our existing certificates in order to create a CSR for a new one?  What am I missing here?

Thank you,

Hi Iamagrump,

To use the Wizard, open IIS Manager, expand all local computer folders, and then expand the Web Sites folder. Right-click the Web site for which you want to obtain a certificate, and then click Properties. On the Directory Security tab, under Secure communications, click Server Certificate. On the first page of the Wizard, click Create a new certificate. Follow the steps in the Wizard to create the certificate.


Hope that helps you Iamagrump
regards,

You will have to delete and create a new certificate request because the CSR will need to have vaild information that your self signed certificate did not require.  You should coodinate this so that your system is not without SSL for too long.

Can I install a CA on another server so that I do not have to remove my certificate until I have the new one?  Then once I have the new one, I can just install it on my server and I'm good, right?  ehh?

You can create another dummy website on the same server generate the request with the proper site name then install the cert on the real site.  I would not use an entirely different server.

How can I change the Organization name on my server?  The have Inc. on the end of our whois instead of Corporation, so I need to change it because the request does not match the whois record.

Yes.  I am clicking to "renew" my certificate in the IIS Server Certificate screen.  When it creates the certreq.txt file, it is creating it with an organization name of Acme Services Corporation.  The 3rd party verify will not issue the certificate, because the whois record for our domain is Acme Services, Inc.

So the 3rd party verifier will not issuer the cert because the whois and requestor name don't match.

Do I need to delete the existing cert altogther?  I can't remember when it asked for the company name. I was hoping to just have my existing cert renewed with the 3rd party.

You are getting a new cert from a 3rd party vendor.  You can't click renew because your current cert is self signed.  You are better off removing the current self signed certificate on the site and generate a brand new certificate request with the right info then install the 3rd party certificate when you get it and you are done.

Mental note:  Verify your WHOIS record before submitting a new CSR.  I had to wait until today to get our ssl back up and running because our WHOIS record had a previous address and the incorrect Company name.
