I recently encountered an unusual issue when upgrading from Operation Manager 2012 SP1 to Operation Manager 2012 R2. Actually, update itself did not cause any problems, everything went well. However, after the upgrade each time when I ran the web console a window appeared with a proposal to do an additional setup.
This issue occurs because the system cannot retrieve trusted and untrusted certificate trust lists (CTLs). If the system does not have access to Windows Update, either because the system is not connected to the Internet or because Windows Update is blocked by firewall rules, the network retrieval times out before the service can continue its startup procedure. In some cases, this network retrieval time-out may exceed the service startup time-out of 30 seconds. If a service cannot report that startup completed after 30 seconds, the service control manager (SCM) stops the service.
Assume that you apply the update that is described in Microsoft Knowledge Base (KB) article 2677070 on a computer that is running Microsoft SQL Server Reporting Services (SSRS). When you try to start SSRS, you receive a time-out error, and event ID 7000 and event ID 7009 are logged in the Application log.
