I'm running Essential Business Server, which integrates SCE along with a few other server products. On the Secuirty Server, running Forefront TMG, we've recently seen the MonitoringHost.exe max out the CPU. This KB OK to apply this hotfix: http://support.microsoft.com/kb/954903 sounds like a good fit for this problem, and the mommodules.dll that we have is slightly older than what's delivered in this hotfix. Any issues with putting this hotfix into SCE within EBS?Thankstgoddard
