Has anyone seen this problem? It happens randomly on my network to clients.

I'm running PPTP Client on several Mikrotik boxes. After 5 minutes the connection will drop, re-dial and connect again. This keeps happening in a loop.

However if I delete the connection, re-add it, it works fine. It is not a problem with my PPTP Server as other clients have been connected for days, months, etc.

Any ideas?
