Disable MySite and MyLinks in Sharepoint (MOSS) 2007

Post from: http://geekswithblogs.net/RogueCoder/archive/2006/11/01/95766.aspx

In order to turn off or disable the MySite or MyLinks functionality you need to be an Sharepoint administrator.

Go to the Central Administration Web Page
Click on the link for Shared Services Administration
--If you have more than one SSP, select the one that is running the MySites functionality
Under "User Profiles and My Sites" click Personalization Services Permissions

Select the group you want to limit the functionality for. More than likely you will just have NTAuthority\Authenticated Users.

In the next screen you will see a list of checkboxes,
--To disable MySites uncheck "Create Personal Site"
--To disable MyLinks uncheck "Use Personal Features"
