Multiple Instances of msiexec.exe When C-State is Enabled
Posted by William Diaz on August 4, 2011
We recently started seeing a rash of performance issues and various program setup failures on different models of workstations. The problem can be identified as multiple instances of msiexec.exe running along side ccmsetup.exe:
The performance issues I have seen were disk related, while others noted program installation failures. This seems to specific to McAfee HIPS, ccmsetup.exe, permissions and a setting in the BIOS for C-State. C-State throttles the cores on multicore processors based on demand. To workaround, we have been disabling the C-State option under the Performance area in the BIOS.
I believe his TechNet Blog addresses the issue officially: http://blogs.technet.com/b/configurationmgr/archive/2011/10/31/information-regarding-mcafee-access-protection-rule-and-configmgr-2007-ccmexec-exe-behavior.aspx
