When you try to perform a task that requires elevated user rights, you do not receive a response in Windows Vista

You do not receive a response when you try to perform any one of the following tasks in Windows Vista:

• Click any of the buttons on the sidebar in Backup and Restore Center.
• Modify the settings for Windows Firewall.
• Modify the settings for Offline Files.

Additionally, you do not receive a message or an error.

This problem occurs if the following conditions are true:

• The following Group Policy setting is configured to automatically deny elevation requests:
  Computer Configuration\Windows Settings\Security Settings\Local Policies\Security Options\User Account Control: Behavior of the elevation prompt for standard users
• You tried to perform a task that requires elevated user rights.

To resolve this problem, return the User Account Control: Behavior of the elevation prompt for standard users policy setting to its default settings. By default, this policy setting prompts for credentials when a standard user tries to perform a task that requires elevated user rights. To return the policy setting to its default settings, follow these steps.

Note If domain-level policy settings are defined, they override local policy settings. In this case, the policy setting must be changed at the domain level.

1. Log on to Windows Vista by using administrative credentials.
2. Click Start.
3. In the Start Search box, type gpedit.msc.
4. In the search results, right-click gpedit, and then click Run as administrator.
5. If you are prompted, enter a password in the User Account Control dialog box, and then click OK, or click Continue.
6. Under Computer Configuration, expand Windows Settings, expand Security Settings, and then expand Local Policies.
7. Click Security Options, and then double-click User Account Control: Behavior of the elevation prompt for standard users.
8. In the list, click Prompt for credentials, and then click OK.
9. Exit Group Policy Object Editor.
