In our domain we have a Windows 2003 SP2 Enterprise Certificate Server, our domain controllers have a policy so that the auto renew a certificate from the certificate server. We have an application that uses secure LDAP (ldap/ssl) to communicate with these domain controllers,  so we need to reboot the servers after the 30 day befor expiration window in which they get the new SSL and before the old one expires. What is a good way to monitor when they get a new certificate, is there an event log entry or something we can monitor?

Logon to your Win2k3 certificate server, and run the Certification Authority console, there you should see the certificate server, under there when you click on the "issued certificates", you should see all the info as to when the certificate was issued etc.

You can also check out this script that you can run - you might want to modify it for your own purposes for the appropriate certificate type(s):

Building on the last suggestion, that may be easier if you're not into modifying scripts.  Set a calendar reminder to run and then you can check the CA and you can filter certificates that expire after a specified date and before another specified date.  You can export this to .csv as well if you want a spreadsheet.
