SSP Creation stuck at Provisioning in Progress
So you are building a SharePoint farm and your doing several tasks not in a particular order. You created a bunch of site collections, you worked on some UI customizations and you realized you haven't provisioned mysite, so you try to configure your SSP. At this point the Create SSP page times out with an error "Timer Job could not be completed and it will be re-tried after some time".
At some point your WFE server's timer job definitions went out of synch from your config DB. This is one of the root causes for lot of issues related to timer jobs. So once again clearing the file system cache come to the rescue!
Steps to Clear the File System Cache
Follow the instructions from the link above and wait for couple of hours. Go to your SSP Admin page, SSP will appear automatically because your server promised that it will re-try the timer job at a regular interval until it completes successfully.
