Okay, so, we did something bad. :-\
When we were first learning about SharePoint and MS Project, we created a 2 or three 'training'/'test' sites (say, PWA_Test and PWA_Train). These, of course, needed their own databases and such. Well, months later, after we got the full enchilada up and "running", our DBA was going to write some backup routines for our SharePoint/Project sites and decided we no longer needed the old test and training databases so he deleted them.
We didn't notice anything wrong as we never went to those sites anymore. Then we had an error on our production project site and checked the event log to find that it was utterly filled with SharePoint errors claiming that syncing failed because they can't find their respective databases. By this time our backups of those old training and test databases no longer existed as they were a "waste of space".
So now we can't figure out how to remove the old sites without, basically, wiping the machine clean and starting fresh (which isn't really an option at all at the moment).
Any idea how to properly remove these old sites or "turn them off"?
I really appreciate it, in advance, if you do.
