"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Inadequate information above, but what I have done for this is:

1. For site-to-site tunnels: Delete tunnels at each end in the router setup, restart both routers (at each end) and remake the tunnels.

2. For client-to-site tunnels:  Delete the tunnel at the router end, restart the router and remake the tunnel. Test the client and remake the client profile if need be.

The above works for me at all my clients.
Shut down tunnel, or removing NHRP  for a period of time and configure it again, should be sufficient to reset DMVPN tunnel.
