When a service is starting, it has to communicate with the service controller in 30 seconds time (standard), if it doesn't, the service controller considers the service failed and kills it. I've had the same problem with the service tier of NAV2009R2. I fixed it in this way: You have to increase the time before the service controller kills a service. I upped it to 2 minutes to be sure.
