Gpupdate not updating computer policy

LDIFDE This tool is used to import and export directory information.

You can use LDIFDE to help you perform advanced backup and recovery of policy settings that are stored outside of GPOs.

Gpupdate replaces the SECEDIT /refreshpolicy tool that was available in Windows 2000.

If you type gpupdate at a command prompt, both the Computer Configuration settings and the User Configuration settings in Group Policy will be refreshed on the local computer.

My Question, and forgive me for putting it here, I had no idea where else to put it, I thought about tutorials, but I know this... Whenever I check Windows Update, I get a message that says "Windows Update cannot currently check for updates, because updates on this computer are controlled by your system administrator".
