Re: Access is Denied after Win2K to XP Upgrade

Tech-Archive recommends: Fix windows errors by optimizing your registry

Start the Windows Management Instrumentation (WMI) service, the Network
Connections service and DCOM Server Process Launcher. Also set them all to
Automatic.

You can get online w/o the Network Connections service running, but the
Network Connections folder won't work right.

[[Note the following things will fail if this service is not running:
• The builtin defrag will fail to work, and if running defrag from the
command line one gets this error:
Windows cannot connect to the Disk Defragmenter engine

• System Information (MsInfo32) will fail to work and give this error:
Can't Collect Information
A network error occurred in connecting to Windows Management
Instrumentation. Ensure that your network connection is
functioning properly.

• If Windows Firewall is enabled, then it will fail to start and all
incomming traffic will be blocked. More Info MS KB 892199
http://support.microsoft.com/kb/892199

• Disk Management will fail and give this error:
The RPC server is unavailable

• The install of new applications will fail and give this error:
The InstallShield Engine (iKernel.exe) could not be launched.
The RPC server is unavailable. ]]

DCOM Server Process Launcher

[[Note if this service is stopped, it will at least have the following
effects:
Actions that requires WMI will give errors like:
Interface: Class not registered

Win32: The service cannot be started, either because it is disabled or
because it has no enabled devices associated with it

* Unable to see Service Dependencies using Services.msc
* Unable to select Properties for the Computer Management (Local) using
CompMgmt.msc
* Unable to see System Information using MsInfo32
* (WinXP) Will experience long delays with System restore (Or not work at
all) ]]

[[CAUSE
The error message occurs if the Windows Management Instrumentation (WMI)
service is not started. This can occur if the service is disabled, if a
dependent service is not started, or if a problem is preventing the WMI
service from starting. The System Information utility will be able to
collect information after the WMI service is started. ]]

In news:9CD5B3B5-5F70-4D27-A141-5EF4898CDB8F@xxxxxxxxxxxxx,
MOW <MOW@xxxxxxxxxxxxxxxxxxxxxxxxx> hunted and pecked:
I have just upgraded a laptop from Windows 2000 Service Pack 4 to Windows
XP Service Pack 2 and since doing so I cannot get access to WMI data.
I've also noted the following symptoms:

- Can't see any Network Connections in the Network Connections folder.
- Receive an error 0x800A0046 when running Windows Updates.
- Receive the message WMI: Access is denied when looking at service
dependencies.
- Receive the message "Can't collect information" when using MSinfo.
- Receive the message "WMI: Access is Denied" when looking at the
properties of WMI Control under Computer Management.

So far I've:
- Done everything in Knowledge Base articles 254631 and 823775
- I've run the command "rundll32.exe setupapi,InstallHinfSection WBEM 132
%windir%\inf\wbemoc.inf" to rebuild the WMI database.
- I've reregistered all the WMI components.
- I've deleted the repository folder (and saw that it was recreated).
- I've checked that the SERVICE account has the "Impersonate a client
after authenitcation" permission.
- I've checked that all necessary services are running with the correct
credentials.
- I've checked the DCOM default impersonate and authenication levels.
- I've removed the machine from the domain.
- I've checked and compared the registry permissions to a working machine
using AccessEnum for SysInternals.
- I've run an inplace upgrade (repair) install, starting from Windows and
starting from booting from the CD.

I'm pretty sure this is simply a permissions problem, but can't for the
life of me find where the problem is. Is there anything else to try
before a clean install?

Thanks
