What is the authentication mode you are using on your WCF Service? Seems like the winform app is running and providing the correct credentials while your windows service is not running with the specified privileges or the credentials being passed are not valid. Try to inspect your request using Fiddler when made from you winforms vs Windwos service and see the difference.
