The optimum solution is to discover what you had configured as the enable secret:
- try the password with CAP lock on, and try with it off.
- try the password with a trailing space.
- try the password with various possible keystroke errors (perhaps a t instead of a g, etc).
The next best solution is to have out of band access to the router (perhaps a modem connected to the console port).
The next best solution is to ship a replacement router to the site and have someone replace the existing router (for which you do not know the password) with a router for which you do know the password.
The ultimate fallback solution is to plan a trip to the remote location and to do the password recovery procedure.
