Hello,
Please try the following solutions:
Option 1: Check GPO Enforcement via Group Policy Management
If this is a domain-joined machine:
- Open Group Policy Management (gpmc.msc).
- Locate the applied Group Policy Object (GPO) for the affected machine under:
• Computer Configuration -> Policies -> Windows Settings -> Security Settings -> Account Policies -> Account Lockout Policy
- If the settings are enforced at the domain level, you cannot change them locally.
- To modify, you need Domain Admin rights to edit the applicable GPO in Active Directory.
If this is a domain-joined machine:
Option 2: Use secpol.msc for Local Security Policy (If Not Domain-Joined)
If this is a workgroup or standalone machine, try:
- Run secpol.msc (Local Security Policy).
- Navigate to:
Security Settings -> Account Policies -> Account Lockout Policy
Option 3: Verify Using RSOP (Resultant Set of Policy)
To check the applied policies:
- Open Command Prompt (Admin) and run:
gpresult /h C:\GPOReport.html - Open the generated GPOReport.html file to see which GPO is enforcing the policy.
Option 4: Check Permissions & Registry Lockdown
If you’re using an admin account and still cannot modify settings:
• Try running Group Policy Editor as SYSTEM:
psexec -i -s mmc
• If you must modify via the registry (not recommended for GPO-enforced settings):
- Take ownership of HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\RemoteAccess\Parameters\AccountLockout.
- Grant Full Control permissions to administrators.
- Modify the registry values.
- Reboot the system to apply changes.
Thanks,
