Delete the lock file \data\db\mongod.lock, and run mongod --repair.

On Windows I just needed to run mongod --repair – Trent Seed Nov 20 '13 at 07:14
Be warned that doing this on a large database will take potentially many hours and requires enough disk space for another copy of the entire database. You also shouldn't need it if you are using journalling. http://docs.mongodb.org/manual/tutorial/recover-data-following-unexpected-shutdown/ – Tom Robinson Nov 22 '13 at 09:51

You definitely want to run repair if you remove the lock file. If you do run mongodb with journaling you should not have to repair. More info on both can be found at http://www.mongodb.org/display/DOCS/Durability+and+Repair

Bugfix If it don´t help to delete the mongodb.lock file, try to repair MongoDB with the command --repair

Start MongoDB as a Service If you want to start MongoDB as a Service you can addthe command --service. if you have multiple instances, cou can use also --serviceName{name} and --serviceDisplayName{name} for uniqe names. You can find here more information about starting as a Service
