    did you or anyone else touch the code of the application and put a new version on the server? If so retrace your steps and see what was added/changed/removed and get it back to a functional state.

    If not check with the IT department which keep the servers alive to see if they had to install a new patch on their servers which might conflict with your application.

    Does the application still run locally or on another server?
