Re: .Net (C#) Service Fails To Start

One technique you could try if all else fails is to insert a try/catch block
around all of the code in your OnStart() method and show any errors in a
message box. Note this will require your service to have the "Interact With
Desktop" permission. Alternately, you could write the message to a known
file on disk.
