Host unavailable when user is logged off

I am facing a problem that I discov开发者_运维知识库ered while I was implementing a small client/host application.

The client side runs Windows 7 64-bit and machine never turns off but user is automatically logged off after 30 minutes of inactivity. When user is automatically logged off the host becomes unreachable, first I thought the problem was isolated to my application, but after som investigation I discovered that resources and vnc server is also unavailable.

The question might be a bit off limit for this forum but I can't find any reasonable explanation somewhere else. Does anyone know how I can keep user being logged off automatically but with the host still reachable on the network?

You need to have them as services.

Are you connecting to some port opened by a server/service which runs as the user? If so, that's the reason. To circumvent, you need to have the service installed/started independently of the user, for entire machine (using administrator priviledges)
