I have been asked once, what are the differences between local service, local system and network service.
Well , Network Service is the least powerful context on the local machine. Local system and local service has administrative rights on the local machines.
So what are the differences ?
Things get exciting when we see which context is used when accessing network resources …
Local System will use the machine account when accessing network resources while Local Service will use Anonymous. This is only if Kerberos is used . If NTLM is used , then both the local system and local service will use Anonymous.
Network Service will always use the machine account for network resource access on the other hand.
