A WMI filter gone rogue
DNS: Domain name shenanigans
1. SYSVOL folder permission drama
Error message: "The permissions for this GPO in the SYSVOL folder are inconsistent with those in Active Directory"
Issue
Your SYSVOL folder is not letting users log in to the domain due to a conflict of interest with Active Directory.
Fix 1
Grant read access to the corresponding client.
How to do it
Navigate to the SYSVOL folder on your domain controller.
Right-click the folder and navigate to Properties > Security > Advanced > Add.
Enter the name of the user or group.
Select the desired permission for the user.
Fix 2
Bribe it with gpupdate /force. It’ll come around.
How to do it
Open Command Prompt as an administrator.
Type gpupdate /force and press Enter.
Wait for the update to finish. Reboot the system if required.
2. GPO conflict wars
Error message: "Group Policy settings were overwritten by a higher authority (domain controller)"
Issue
Your two GPO settings are fighting over custody.
Fix 1
Use the Group Policy Modeling Wizard to analyze conflicts or adjust GPO precedence.
How to do it
Open Group Policy Management.
Navigate to and right-click Group Policy Modeling. Select Group Policy Modeling Wizard.
Follow the wizard to simulate GPO processing and identify conflicts.
Note: The wizard will simulate how the policies are applied in the specific scenario. It generates a report showing which GPOs are applied, their order of precedence, and any conflicts or errors.
Fix 2
If they don’t stop, give one a timeout (change the precedence order).
How to do it
Open Group Policy Management.
Navigate to the linked GPOs for the affected OU.
Use the up or down arrows to adjust the processing order.
Ensure the GPO with the higher priority is processed last.
3. A local policy corruption meltdown
Error message: "Corrupted Group Policy folder detected"
Issue
The local Registry.pol files are corrupted.
Fix 1
Delete the corrupted Registry.pol files and run gpupdate /force.
How to do it
Delete the corrupt Registry.pol files from the following directory:
C:\Windows\SYSVOL\sysvol\Policies
Run gpupdate /force and let them grow up into fresh, responsible files.
4. A WMI filter gone rogue
Error message: "WBEM_E_PROVIDER_FAILURE"
Issue
A WMI filter is misconfigured.
Fix 1
Use WBEMTEST to validate the WMI query or remove the faulty filter.
How to do it
Open WBEMTEST from the Start menu.
Click the Connect button and enter the Namespace (e.g., root\CIMv2).
Click Connect to establish a connection and test the query.
If it keeps misbehaving, ditch it.
Fix 2
Remove the faulty WMI filter.
How to do it
Open Group Policy Management.
Navigate to WMI Filters.
Expand your domain and click Group Policy Objects.
For each GPO, do the following:
Click the GPO name.
On the right pane, look under the Scope tab.
Check the WMI Filtering section at the bottom. If it says , the GPO has no WMI filter.
If a WMI filter is listed, note its name by doing the following:
Check the linked GPOs.
Expand the OUs on the left pane.
Select the OU where the affected computers or users reside.
Check the list of linked GPOs on the right pane on the Linked Group Policy Objects tab.
Look for any linked GPOs with a WMI filter applied.
Identify the affected systems.
For each GPO with a WMI filter, note the filter name.
Navigate back to the WMI Filters section.
Analyze the query to determine:
What systems or users the filter is targeting (e.g., the OS version, RAM, or CPU).
Whether the filter might exclude systems or users that it should include.
Validate the WMI filter.
Test the WMI query using WBEMTEST or PowerShell on an affected system:
Using WBEMTEST, connect to root\CIMv2 and run the query.
Using PowerShell, enter the following:
Get-WmiObject -Query "" -Namespace "root\CIMv2"
If the query fails or returns no results, the WMI filter is likely the issue.
Check the event logs in the affected systems:
On an affected computer, open Event Viewer.
Navigate to Applications and Services Logs > Microsoft > Windows > GroupPolicy > Operational.
Look for errors or warnings related to GPO application.
Fix or remove the WMI filter.
In Group Policy Management, navigate to the affected GPO.
Right-click the GPO and select Edit.
On the Scope tab:
Navigate to the WMI Filtering section.
Click <none> to remove the WMI filter, or select a different, valid filter.
Click OK to save the changes.
5. DNS: Domain name shenanigans
Error message: "Domain name not available"
Issue
DNS misconfiguration prevents domain authentication.
Fix 1
Set the DNS server to the domain controller’s IP and verify it with nslookup.
How to do it
Open the Network and Sharing Center.
Click Change adapter settings and open the properties of your active network connection.
Select IPv4 and configure the DNS server to point to the domain controller's IP.
Fix 2
Use nslookup to make sure they’re actually talking. It’s networking speed dating.
How to do it
Open Command Prompt.
Run nslookup and test queries to the domain controller's fully qualified domain name (FQDN).
To find your domain controller's FQDN:
Open the Control Panel.
Select System and Security.
Select System. Your Full computer name is your domain controller's FQDN.
