SYMPTOMS

When you start Microsoft Management Console (MMC console) such as services.msc or gpedit.msc, you may get the following error message:

One or more ActiveX controls could not be displayed because either: 1) Your current security settings prohibit running ActiveX controls on this page, or 2) You have blocked a publisher of one of the controls. As a result, the page may not display correctly.

Additionally, when you click OK in the error message, you receive the same error message again.

The desktop sidebar gadgets may also stop working and show as black squares with a green vertical line down the center.

Edit the registry to change a Value data in the Zones registry setting.

In the Value data box, type either 1 or 0 to overwrite the existing value of 3. Then, click OK

The values 0, 1, and 3 are associated with the following behavior:

0 = Enabled, or the action is permitted
1 = Prompt
3 = Disabled, or the action is not permitted

Note If you type 1 in the Value data box, you will receive the following prompt when you start Microsoft Project:
Do you want to allow software such as ActiveX controls and plug-ins to run?
