In my current client engagement I've been working on a MySite implementation, so naturally I've had to mess with the Shared Services Provider quite a bit. For reasons unknown to me, the SSP/MySites got messed up and I had to delete them. The problem was that you can't easily delete a SSP from the central admin, so once again STSADM to the rescue....
stsadm -o deletessp -title <YourSSPTitleHere> -force
The key here is -force, depending on the situation, if you don't add -force, your SSP won't be fully deleted.
