Go into Services and stop the Windows management instumentation Serivce, Then go to C:WINDOWSsystem32wbemRepository and delete all files in their and reboot (the files will be automatically rebuilded) this might work

ok...I've deleted everything from C:WINDOWSsystem32wbemRepository but the problem is still there. Delete the Respository folder as well? or is there any others way beside than formatting?

Thanks for the reply.

I don't know if my problem is related to yours, but I've reinstalled Windows XP Professional 5 times in the past 3 days because of this error. At first I thought it was caused by some Microsoft maintenance update, but the problem was -- ta da:

Nero 5. It came with my new CD burner (with a "Designed for Windows XP" logo!!), and it reproducably destroyed my Windows XP Pro installation.

Apparently it damages something in the system so bad, that WMI doesn't work anymore. I got "WMI: Access denied" with many system components, and Windows Update wouldn't work correctly anymore either.

I've isolated the problem by doing step-by-step reinstallations, and it's definitely Nero 5. I can only recommend not to use it on XP.

CAUTION: If you have Nero 5 installed on XP, don't uninstall it. It won't help. The only solution is to do a complete reinstallation of XP, without Nero. (perhaps there's some fix from Ahead Software, but I haven't looked yet) -- the good aspect is that Nero works and you can do a backup first.

I've tried everything including setting every possible security descriptors for files, registry, DCOM objects and other items in the system -- for me, only a reinstallation worked with from blank system, without Nero 5.

I have no idea if other software can cause the same problems.

Hold it, IT WASN'T NERO 5. :oops:

It was QDI ManageEasy 2.0.

Sorry for any inconvenience if so occurred. I installed QDI ManageEasy always right before Nero 5, and the error occurred after the 2nd or 3rd reboot.

The error occurred when installing from the QDI CD that came with the motherboard (PlatiniX 4).

I downloaded QDI ManageEasy 2.012 from the QDI website, and with that, it seems to work so far.

Also, on XP the problem can be corrected by rolling the system back to the last functional restore point. I haven't tried uninstall yet, but I saw that the 2.0 version overwrote some files in the system32 directory, so I guess a rollback was the right thing to do.

With 2.012 I haven't had the problem again yet since.

i've got exactly the same problem now:

("Can't Collect Information Access denied to Windows Management Instrumentation
server on this computer . Have an administrator change your access permission.")

Just wandered how this one was solved

any ideas apart from reinstall ?

Thanks.

I am seeing a bunch of you having problems with WMI. Here is the solution:
If you make a copy of %windir%infwbemoc.inf (for example, wbemoc_reinstall.inf), and add these lines to the top of it:

[Components]
WBEM=ocgen.dll,OcEntry,wbemoc.inf,,7

Then you can run this command and step through the wizard:

sysocmgr /i:wbemoc_reinstall.inf /f

Afterward, check %windir%system32wbemlogssetup.log to verify that all mofs were loaded.

Note that during normal installation, winmgmt is partially disabled to increase setup performance and eliminate potential conflicts that can arise when updating schema while providers are active. Since NT setup will not be in progress this time, winmgmt will be fully active and it is possible that this process may take longer than usual and you may run into some conflicts.
