Did you change the Link Order in the OU? Otherwise the GPO on domain level will win.

You will need to check the precedence of the GPOs under the inheritance tab in GPMC if they are at the same level.

Normally GPOs apply in this order: site, domain, OU and child OU. As a result, your GPO applied at the child OU level should overwrite the settings. From what you are saying, however, it sounds like this isn't happening.

Have you tried to enforce the GPO at the child OU?

If you don't want any of the settings from the default domain GPO, you could block inheritance from GPMC.

There are two ways you can go about this.

1. Block inheritance and link all the GPOs that are required directly to the child OU. Take care of the precedence order.

2. Enforce the GPO containing your default homepage settings.

Try both methods on a test OU with a test user and see which one works better for you.

Blocking and Enforcing is not best practice.

Unless the GPO that is linked to the domain is configured as "Enforced", GPOs linked directly to OUs will take precedence by default. Setting a GPO to be "Enforced" causes it to take precedence on the OUs it is linked to and all child OUs. Using the Enforced setting is not a best practice because it complicates troubleshooting efforts. Right click the GPO that is linked to the Domain and make sure the Enforced option doesn't have a Checkmark next to it. If it does, click on it to remove the checkmark so it isn't enforced anymore. Once you do that, your GPOs linked to the child OUs you want should then take precedence. Enforced GPOs will *always* win when the settings in other GPOs are different. You can't keep this from happening by changing link order in GPMC, so make sure that Domain level GPO setting the home page isn't enforced.
