Windows Services - Best practices question???

Question

Hi All, I'm not sure if this is the place to post this question but I didn't see a forum just for Windows Services. If anyone can please help me by answering my questions or by pointing me in the right direction I'd really appreciate it. I wanted to know which is better, to have one service in one process or to have multiple services in one process? I see that in .NET it allows you to start multiple services under one process. Also, if one of your services crashes does it crash all of the services that are in the same process? I'm new to .NET and C# so any help would be highly appreciated. Can anyone point me to some real good samples for Windows Services because all the ones I find are so basic they have no meat and potatos to them.
