"svchost.exe -k LocalServiceNoNetwork" is to invoke the svchost.exe program to load the DLL file for the given service specified in the registry. The loaded DLL file will be executed under a shared process of svchost.exe named as the LocalServiceNoNetwork group as specified by the parameter "-k".

But services of a shared process have execution environment dependence. If one service is running into problem, all other services of the same process will be impacted.
