Some of my Windows 2008 R2 servers have been reaching over our 80% committed memory threshold more often than preferred. There is a hotfix out as noted on Kevin Holman’s OpsMgr Blog – http://blogs.technet.com/b/kevinholman/archive/2010/06/09/wmi-leaks-memory-on-server-2008-r2-monitored-agents.aspx , however the server admins have not tested and deployed the hotfix yet so in the mean time I needed an efficient way to bounce the WMI service along with dependencies.
In case anyone else if having this issue… This is the script I am using as a Recovery Task with Winmgmt as its parameter to run and sorry if I made any mistakes this is only my third PowerShell script! Feel free to change and let me know if there is a better way! .. NOTE: You will probably need to sign the code unless you changed the PowerShell script execution policy to Unrestricted !
