Introduction What is WMI? ◦Wikipedia: “WMI is Microsoft's implementation of the Web-Based Enterprise Management (WBEM) and Common Information Model (CIM) standards from the Distributed Management Task Force (DMTF).MicrosoftWeb-Based Enterprise ManagementCommon Information ModelDistributed Management Task Force ◦SMS 2.0 MOC: “WMI does for management software what printer drivers did for printing” ◦Me: “ The registry on steroids.”

WMI basics (1) Namespaces Classes Methods Properties ◦Embedded properties  Props  Proplists  regmultistringlists ◦Lazy properties

WMI basics (2) Providers ◦regProv ◦regPropProv ◦Disk & CPU ◦View instance provider ◦AI Providers (aainstprov) ◦Write your own ( i-provider-to-list-the-monitors-serialnr-and-model-name.aspx) i-provider-to-list-the-monitors-serialnr-and-model-name.aspx Events ◦SELECT * FROM __InstanceModificationEvent WITHIN 10 WHERE TargetInstance ISA 'SMS_Collection' Qualifiers ◦Dynamic ◦CimType

Troubleshoot WMI Wmidiag Repair ◦XP SP2+  rundll32 wbemupgd, UpgradeRepository ◦Vista and above (Needs to be Run as administrator)  winmgmt /salvagerepository ◦Windows server 2003  rundll32 wbemupgd, RepairWMISetup Re-register wmi components ◦cd /d %windir%\system32\wbem ◦for %i in (*.dll) do RegSvr32 -s %i ◦for %i in (*.exe) do %i /RegServer Rebuild repository as a last resort (Might kill other applications) ◦Net stop winmgmt ◦Ren %windir%\System32\Wbem\Repository %windir%\System32\Wbem\Repository_Bad ◦Net start winmgmt

Extended WQL Extended Wql ( ) ◦Select x from class ◦Other keywords  Distinct, count, join, where, order by  In / not in  GetDate, datediff, dateadd SELECT DISTINCT SMS_MonthlyUsageSummary.ResourceID FROM SMS_MonthlyUsageSummary INNER JOIN SMS_MeteredFiles ON SMS_MonthlyUsageSummary.FileID = SMS_MeteredFile.MeteredFileID WHERE DateDiff(day,SMS_MonthlyUsageSummary.LastUsage, GetDate()) < 90 AND SMS_MeteredFiles.RuleID = 6

WMI Tools Wbemtest Cim studio Wmic ◦ to-the-configmgr-2007-admin-console-1.aspxhttp://scug.be/blogs/sccm/archive/2009/09/15/adding-wmic-right-click-actions- to-the-configmgr-2007-admin-console-1.aspx Policyspy Script SDK ◦ AD-E3AF6218EDCC&displaylang=enhttp:// AD-E3AF6218EDCC&displaylang=en

WMI in ConfigMgr (1) Omni-Present ◦SMS Provider / Administrator console ◦Dynamic Collections ◦Queries ◦Hardware inventory ◦ConfigMgr client settings store

WMI in ConfigMgr (2) Namespaces used by Sccm ◦Server side  Root\sms (sms_providerlocation)  Root\sms\site_sitecode ◦Client side  Root\ccm  Root\ccm\invagt  Root\ccm\policy Sccm wmi Class structure ◦Abstract classes (Require sitecode='xyz')  Sms_sci  Sms_siib ◦Sms_r* ◦Sms_g* ◦Sms_cm_res_coll_collid

Advanced WMI in Configuratio Manager Local Policies ◦ us/magazine/ customizesms.aspxhttp://technet.microsoft.com/en- us/magazine/ customizesms.aspx ◦Examples  Request permission for Remote Tools  Custom Hardware Inventory  Disable individual agents [CCM_Policy_PartialPolicy(true)] instance of CCM_SoftwareDistributionClientConfig {SiteSettingsKey = 1; PolicySource = "Local"; // override only this property, all others from the Site/Management Point [CCM_Policy_Override(true)] Enabled = FALSE;};

SccmAutoDoc What is SccmAutodoc? 1.My source for getting to know WMI in ConfigMgr 2.A program that, based on WMI queries automatically documents your site settings Where can I get SccmAutodoc? ◦SccmAutodoc is currently in beta and can be downloaded from Is SccmAutodoc freeware? ◦SccmAutodoc will become moderately priced software once it leaves the beta stages, hopefully somewhere near the end of this year.
