What is the Security Identifier (SID) for the Network Service Account on Windows OS?

• S-1-5-19
• S-1-5-17
• S-1-5-7
• S-1-5-20 

 

EXPLANATION

This is one of the well-known SIDs in a Windows operating system. It presents the computer's credentials (e.g. MANGO$) to remote servers and has its own profile under the HKEY_USERS registry key (HKEY_USERS\S-1-5-20). If you try to schedule a task using it, enter NETWORK SERVICE into the Select User or Group dialog. This account is meant to run standard least-privileged services.and is far more limited than Local System (or even Administrator) but still has the right to access the network as the machine.
