FIM 2010 RC1 update 2

Update 2 for Forefront Identity Manager 2010 RC1 was publicly released yesterday on windowsupdate.
This patch applies to:
- the FIM synchronization service
- the FIM service

Before installing these optional updates:
- stop the FIM service
- stop the FIM synchronization service

Additionaly, you have to apply these updates in the following order:
- FIM 2010 RC1 update 2 for FIM SERVICE
- FIM 2010 RC1 update 2 for FIM SYNCHRONIZATION SERVICE

Since the update 1 failed if we used a non self signed certificate, altough I was not sure it was necessary, I did the temporary certificate replacement before Forefront Identity Manager 2010 RC1 update 1 trick.

It ows the KB977312. You can check details on the Microsoft Support website.
I advise you to read this article on Jorge's blog.

How to install the FIM RC1 2010 Update 2 with a custom certificate:

1. Back up the FIM Service database.
2. Start regedit, and navigate to \HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\FimService. Find the value for CertificateThumbprint, and save it for later use.
3. Uninstall the FIM Service and Portal.
4. Reinstall the RC1 version of the FIM Service and Portal, with the options Re-use existing database and Use self-issued certificate. This allows the FIM Service installer create the certificate.
5. Install FIM 2010 RC1 Update 2.
6. After installation is complete, start regedit, and navigate to the registry key \HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\FimService. Change the value of CertificateThumbprint to the value that you saved previously.
7. Restart the FIM Service.
