Having run the Products & Technologies Configuration Wizard, you’ll want to run up Central Administration to complete the configuration of your SharePoint installation. Depending on your environment you might need to perform these 2 additional steps before you launch Central Administration, otherwise you might find that IE starts complaining about trusted sites and you get the nag prompt to enter your Network credentials.

These instructions are valid for IE7 and IE8.

Add the SharePoint Central Administration site to the list of trusted sites

1. In Internet Explorer, on the Tools menu, click Internet Options.
2. On the Security tab, select the “Trusted Sites” zone and click the Sites button.
3. Clear the “Require server verification (https:) checkbox for all sites in this zone” check box.
4. In the “Add this Web site to the zone” box, type the URL for the SharePoint Central Administration site, and then click Add.
5. Select the “Require server verification (https:) for all sites in this zone” check box.
6. Click Close.
7. Click OK.
