Enterprise Features
Enable Enterprise features
In the event an administrator decides to install Microsoft Office SharePoint Server 2007 by using the Standard license type, the following features are available:
Collaboration
Enterprise content management
Workflow
My Sites
Profiles and personalization
Enterprise search

On the other hand, a SharePoint Administrator can convert the license type to the Enterprise license, which would enable and, allow the SharePoint Administrator to push down the Enterprise feature set to all sites within a server farm. The following additional features, in conjunction with the Standard license features, are available with the Enterprise license type:
Business Data Catalog
Excel Services
Report Center
InfoPath Forms Services

Enable Enterprise features
In Central Administration, on the Operations tab, under Upgrade and Migration, click Enable Enterprise Features.
On the Enable Enterprise Features page, under Use these features, click Enterprise (Requires Enterprise client license).



In the Enter Product Key box, type the Enterprise Client license key.
Important You cannot return to using the Standard feature set after you have enabled the Enterprise feature set. If you want to return to using only the Standard features, you must turn off all of the Enterprise features on all sites. Alternatively, you can uninstall Office SharePoint Server 2007, reinstall it by using the Standard license type and create a new server farm, and then attach the content databases to the new farm. BTW, bad, bad, bad….
Enable features on existing sites
In Central Administration, on the Operations tab, under Upgrade and Migration, click Enable Features on existing sites.






On the Enable Features on existing sites page, select the Enable all sites in this installation to use the following set of features check box.




After enabling features for all sites, you will note the enabling status displaying a status of Initializing.
In essence, the configuration of the features allows a SharePoint Administrator to manage the features at both the Farm and Web Application level.
