Don't forget you have to set the service to manual instead of automatic. To do this click Start>>>Run
type services.msc
scroll down to the Windows zero Configuration service right click, select properties
There is a drop down box next to start-up type, click on the arrow and select manual - ensure you are connected to your network whilst doing this else windows will be unaware what connection you wish it to stay with.

Then click OK
