Speaking of CA server, I have a question: I am soon going to re-host my single tier CA from a server 2003 server to a server 2008 r2 server. I've done this in our test environment, and it worked just like the docs said it would.
My question: is there any way to extend the expiration time of the master certificate either when I do the migration, or afterward? I'm getting really tired of all sorts of stuff breaking every few years when our oddball certs expire. -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Tammy George Sent: Thursday, August 15, 2013 2:21 PM To: '[email protected]' Subject: RE: [NTSysADM] Certificate Authority expiration/renewal Thanks for the responses. We have a single-tier CA and I'm renewing it tomorrow morning.

We have a two-tier CA, and this is the procedure I worked out: The root certificate doesn’t expire until 2016, but the CRL expires every 180 days. o- Fire up the root CA - we use a 2008 R2 VM that's not joined to the domain o- Log in with the local Administrator account o- Start a command prompt (run as administrator) o- cd to c:\windows\system32\certsrv\certentroll o- issue the command "certutil -crl" (or use the GUI, as per http://technet.microsoft.com/en-us/library/cc778151%28v=ws.10%29.aspx)) o- verify that the date on the CRL file in your current directory has the current date/time o- map a drive to C$ (say, X:) on the issuing CA using your DA credentials o- copy the above CRL file to X:\\windows\system32\certsrv\certentroll o- shut down the root CA o- log into the issuing CA with your DA credentials o- issue the command "certutil -crl" (or use the GUI, as per http://technet.microsoft.com/en-us/library/cc778151%28v=ws.10%29.aspx)) Set a reminder for 170 days - which gives you 10 days notice to renew.
