After installing the latest cumulative updates to OCS 2007 R2 some services don’t start

[tweetmeme source=”stalehansen” only_single=false]I have experienced this issue in my latest OCS deployments now and want to share this information. This issue happens after installing the january cumulative updates server-side. This issue is not related to the CryptoAPI issue described here: https://msunified.net/2009/10/14/for-now-hold-off-on-installing-kb-974571-on-ocs-2007-r2-servers-and-possibly-r1/

The Problem 

  • I have experienced this issue on Enterprise Front End servers and Mediation servers
  • The after reboot it takes for ages to be able to connect through RDP, ping works fine
  • When you finally log in you find that the Front End or Mediation service has not started
  • When you start the services everything works fine

The Solution 

  • Set the services below to automatic start
    • [Winmgmt] – Windows Management Instrumentation
    • [Keyiso] – CNG Key Isolation
    • [WMIapsrv] – WMI Performance Server
    • [Rasman] – Remote Access Connection Manager
  • On the Enterprise Front End server set the rtcsvr dependent on the above services
    • Open Command Prompt as administrator and run the below command
    • sc config rtcsrv depend= WinMgmt/KeyIso/WmiApsrv/rasman 
  • On the Mediation server set the rtcmedsrv dependent on the above services
    • Open Command Prompt as administrator and run the below command
    • sc config rtcmedsrv depend= WinMgmt/KeyIso/WmiApsrv/rasman

  1. This happens to server with HP WBEM software… Uninstalling this HP software solves the problem. :)

  2. Has anyone seen this issue on Windows 2008 R2?

    I’m trying to build out an OCS 2007 R2 Director (on a Standard Edition Front End), and seem to have hit this issue.

    Unfortunately the tips above don’t seem to help :(
