I recently needed to disable compatibility view for intranet sites for all domain users and found that using Group Policy was the easiest solution.

Group Policy:
Policy: Turn on Internet Explorer Standards Mode for local intranet  (Enabled this disables compatibility view for local intranet sites.  Supported on at least Internet Explorer 8.0)  
Category Path: Computer ConfigurationAdministrative TemplatesWindows ComponentsInternet Explorercompatibility view
 
Compatibility View GPO Explanations:

To enable Compatibility View for multiple computers in an enterprise environment, administrators can use the following new Compatibility View Group Policy settings that are available for Internet Explorer 8 and for Internet Explorer 9:

  • Turn on Internet Explorer 7 Standards Mode: This setting enables Compatibility View for all websites and prevents users from enabling or disabling Compatibility View for any websites.
  • Turn off Compatibility View: This setting disables Compatibility View for all websites and prevents users from enabling or disabling Compatibility View for any websites.
  • Turn on Internet Explorer Standards Mode for Local Intranet: This setting disables Compatibility View (enables Standards Mode) for all intranet websites.
  • Use Policy List of Internet Explorer 7 sites: This setting lets administrators add specific sites that must be viewed in Compatibility View. Users can add or remove sites from the list. However, they cannot remove sites that are specified by the administrator.
  • Turn off Compatibility View button: This setting prevents users from using the Compatibility View button to try to fix websites.

These settings are available for both Users and Computers in the following location for each site, domain, and organizational unit:
