ERROR_WMI_DP_FAILED 0x00001071 Fix for Windows

Yeah, this one's annoying — especially when it pops up in the middle of a deployment script or on a machine you can't easily reboot. Let's skip the throat-clearing and fix it.

The fix (do this first)

Open an elevated Command Prompt or PowerShell. If you're not admin, the rest of this is a waste of your time. Ninety percent of 0x00001071 hits go away after you verify and, if needed, rebuild the WMI repository. Run the verify first — it tells you whether the repo is actually corrupt before you start nuking things.

winmgmt /verifyrepository

If it says WMI repository is consistent, the repo isn't your problem — skip to the provider re-registration below. If it says inconsistent, salvage it:

winmgmt /salvagerepository

Salvage is non-destructive. If salvage fails or the error comes right back, then you rebuild. Rebuild blows away custom WMI namespaces and any third-party providers that registered into the repo — this is why you don't reach for it first. On a server with SCCM, SCOM, or vSphere agents installed, a rebuild can leave you re-registering those agents. Salvage first, always.

net stop winmgmt /y
cd %windir%\system32\wbem
ren Repository Repository.old
net start winmgmt

Windows will re-create the Repository folder on the next WMI call. Reboot after this — don't try to shortcut it, the provider host process caches too much.

If the repo is fine, your provider is the problem

0x00001071 literally means a data provider failed to execute a request. The WMI service itself is fine; the DLL that's supposed to answer a query blew up. Common offenders: antivirus WMI providers (CrowdStrike, older Symantec builds), the Dell Command | Monitor provider, and the Microsoft Storage Spaces provider on servers with degraded pools.

Find the culprit by watching the Application log for Event ID 5858 from WMI-Activity. It names the provider and the namespace. That's your target.

Once you've got the provider name, re-register its DLL with regsvr32. For example, on a machine where the storage provider is the problem:

regsvr32 /s %windir%\system32\wbem\storagewmi.dll
regsvr32 /s %windir%\system32\wbem\wmiprovider.dll

For third-party providers, the vendor's installer usually has a repair option. Use it. Doing it by hand is a coin flip.

Why this works

WMI is three pieces: the service (winmgmt), the repository (a hierarchical store of class definitions), and providers (DLLs that translate WMI queries into real answers from the OS, hardware, or apps). 0x00001071 is thrown when a provider is asked to do something and either returns a failure or crashes. If the repository is inconsistent, the provider can't resolve the class definitions it needs and fails — that's why the rebuild fixes so many cases. If the repo is fine but the DLL is unregistered or damaged, same result. Verify catches the first, event log plus regsvr32 catches the second.

Less common variations

Per-user repository corruption. Rare, but the error only triggers under one profile. Test with a different admin account. If it works there, it's a profile issue — rebuild the user's WMI namespace or just recreate the profile.
Namespace permissions. Someone tightened ACLs on root\cimv2 or a vendor namespace. Run wmimgmt.msc, right-click the namespace, check Security. Default is Everyone: Execute Methods, Enable Account, Remote Enable plus Authenticated Users with the same.
64-bit vs 32-bit mismatch. Calling a 64-bit provider from a 32-bit process (or vice versa) gives you this on some legacy apps. Check %windir%\SysWOW64\wbem for the 32-bit store.
DCOM hardening. After a patch cycle, some servers tightened DCOM and broke WMI remote calls. Symptom: local WMI works, remote queries throw 0x00001071. Check dcomcnfg → Component Services → My Computer properties → COM Security, and confirm the calling account has Remote Activation.
Corrupt MOF files. If mofcomp has been run manually and failed halfway, the class definitions are half-baked. Recompile the standard ones: mofcomp %windir%\system32\wbem\cimwin32.mof and .mfl.

Prevention (the boring part that actually matters)

Don't install two AV products with WMI providers. They fight. Pick one and clean the other's provider off the box with its official uninstaller.
Patch Windows deliberately. Half of the DCOM-related WMI breakage I've seen came from a rushed patch Tuesday followed by a zero-day patch two days later. Test on a canary ring.
Back up the WMI repository before major agent installs. Copy %windir%\system32\wbem\Repository to another drive. Takes 30 seconds.
Stop running scripts as SYSTEM when a service account will do. Lots of WMI corruption traces back to scripts racing the provider host at boot.

Reboot after any of the fixes above and re-run winmgmt /verifyrepository to confirm clean. If 0x00001071 persists on a fully rebuilt repo with no third-party providers installed, you're looking at hardware or a disk-level corruption issue — run chkdsk /f on the system volume and consider an in-place repair install of Windows. That's rare but it happens.
