Since installing SP2 on our SharePoint enviornment it seems MySites have been enabled for some users.
Previously when users clicked on peoples names, for example a users name on the bottom of a page where a user has added an item, it would take them to a summary of the user. However since the SP2 install, for some users they no longer have a summary page, instead it is directing them to the MySites page.
I have tried going into the SSP admin, and disabling the MySites as detailed on this site, however there are no groups added to the permissions options, only a select number of users.
Click on the link for Shared Services Administration
Select the group you want to limit the functionality for.
In the next screen you will see a list of checkboxes,
Uncheck Create Personal Site
This does not remove the existing mysites. You need to remove them manually or with a powershell script.
