Thumbprint, think of it as GUID, you generate a new cert... http://www.digicert.com/ssl-support/exchange-private-key-missing.htm
________________________________ From: Steve Hart Sent: Thursday, January 24, 2013 5:31 PM To: MS-Exchange Admin Issues Subject: RE: Exchange 2007 Cert Problem It doesn't show up in the certificates MMC. It doesn't show up in Get-ExchangeCertificate When I try Import-ExchangeCertificate, it says that it's already there. Workaround question: What determines the footprint of a cert? ie How do I get a cert with a different footprint? Change the CSR? Buy a new cert from the CA?

It sounds like at one point you dropped the associated private key, I'd look to see if it was actually still in the store, but from the sounds of it, I doubt it. jlc ________________________________ From: Steve Hart Sent: Thursday, January 24, 2013 4:42 PM To: MS-Exchange Admin Issues Subject: RE: Exchange 2007 Cert Problem Request: [PS] C:\>New-ExchangeCertificate -GenerateRequest -Path c:\mail_wrightimg_com.cs r -KeySize 4096 -SubjectName "c=US, s=Oregon, l=Portland, o=Wright Business Grap hics, cn=mail.wrightimg.com" -DomainName wrightimg.com, autodiscover.wrightimg.c om -PrivateKeyExportable $True Ran the CSR through the provider downloaded the cert files, unzipped them Import: [PS] C:\>Import-ExchangeCertificate -path c:\Certs\1-2013\Cert\wrightimg.com\gd_ iis_intermediates.p7b Worked the first time.
