I have uninstalled and reinstalled mongo (3.0.1), being sure i accepted the network access on windows 8, and yet i still have the same issue of \"waiting on 27017\".
The waiting for connections message in the console output indicates that the mongod.exe process is running successfully.
http://docs.mongodb.org/manual/tutorial/install-mongodb-on-windows/?_ga=1.82566930.525730850.1428016333
Next you need to connect to MongoDB through mongo.exe shell using another command promt.
As soon as you are done with that, the waiting message in first console would change to connection accepted.
Hope that helps :)
