WMI and the ConfigMgr Client

If you still manage Windows XP machines with ConfigMgr I’m sure that you know that 9 out of 10 client health issues are WMI related. Whether it’s the CCM namespace getting corrupt or the entire WMI repository getting corrupt... Windows XP WMI + ConfigMgr = unstable.
Most of the time you can get away with simply deleting the ccm namespace and then reinstalling the ConfigMgr client to correct the problem. (More on that later) However there are times when the fix requires you to rebuild the entire WMI repository – which should be used as a last resort as there could be other applications on the machine that rely on WMI.
After searching around for WMI resources I came across this post which does a great job of detailing different ways to resolve your WMI issues based on your Operating System version. I've used many of these approaches in order to resolve client health issues but I’ve had the most success with the following command:

• From a command prompt run rundll32 wbemupgrd, RepairWMISetup

If you decide that rebuilding the WMI repository is what you need to do follow these steps for Windows XP:

• Open a command prompt and run the following
• net stop winmgmt
• Browse to %windir%\System32\Wbem
• Rename the Repository folder
• Go back to your command prompt and run the following to rebuild your repository
• net start winmgmt

As mentioned before, If you rebuild your WMI repository you run the risk of breaking other applications on that machine that require WMI. A safer method is to simply delete the CCM namespace and then repair the ConfigMgr client. One tool that I now use almost exclusively is SCCM Client Center. SCCM Client Center allows you to do a variety of things but one of the most handy options are it’s client repair options. After you install Client Center connect to the machine in question, (Top left-hand corner) click on the Agent Action menu (highlighted in the screen shot below) and as you can see there are a bunch of actions that you can kick off to repair the ConfigMgr client. Most of the time selecting Delete root \ccm will resolve your problem.



I find myself using this tool everyday for a variety of reasons.

Server 2008 R2 and wmiprvse.exe crashes

Recently I was checking the health of a couple of my primary site servers and as I was going through some of the logs I noticed in the application event log there where event 1000 application errors that kept reoccurring. It seemed that every couple of days wmiprvse.exe would crash and then restart but with little noticeable effect. After some digging I came across a blog entry describing a problem with SCVMM and WMI. It referenced a wmi hotfix (KB981314) that Microsoft released that deals specifically with event 1000 wmiprvse.exe errors. I decided to install the hotfix on the two site servers experiencing the problem as they are in a staging environment. Since installing the hotfix on both servers the number of wmiprvse.exe crashes has dropped significantly. It’s only been about three weeks but things are looking good…
