What Happens When You Grant Permissions To The Network Service Account

Since there is so much confusion almost functionality of standard service accounts, I'll try to give a quick run down.

First the actual accounts:

• LocalService business relationship (preferred)

  A limited service business relationship that is very similar to Network Service and meant to run standard to the lowest degree-privileged services. However, unlike Network Service it accesses the network as an Anonymous user.

  • Name: NT AUTHORITY\LocalService
  • the account has no password (any countersign data yous provide is ignored)
  • HKCU represents the LocalService user account
  • has minimal privileges on the local computer
  • presents anonymous credentials on the network
  • SID: S-1-v-nineteen
  • has its own profile under the HKEY_USERS registry primal (HKEY_USERS\S-1-v-19)

• NetworkService account

  Limited service account that is meant to run standard privileged services. This account is far more limited than Local System (or even Administrator) but still has the right to access the network equally the machine (encounter caveat above).

  • NT AUTHORITY\NetworkService
  • the account has no password (whatever password information yous provide is ignored)
  • HKCU represents the NetworkService user account
  • has minimal privileges on the local computer
  • presents the computer'south credentials (e.g. MANGO$) to remote servers
  • SID: South-1-5-xx
  • has its ain contour under the HKEY_USERS registry key (HKEY_USERS\S-i-5-xx)
  • If trying to schedule a task using it, enter NETWORK SERVICE into the Select User or Grouping dialog

• LocalSystem business relationship (unsafe, don't use!)

  Completely trusted account, more than so than the administrator business relationship. There is zero on a single box that this business relationship cannot do, and information technology has the right to access the network every bit the machine (this requires Active Directory and granting the machine account permissions to something)

  • Name: .\LocalSystem (can besides utilise LocalSystem or ComputerName\LocalSystem)
  • the account has no countersign (any password information you lot provide is ignored)
  • SID: South-ane-5-eighteen
  • does non have any profile of its own (HKCU represents the default user)
  • has extensive privileges on the local calculator
  • presents the computer'due south credentials (e.1000. MANGO$) to remote servers

In a higher place when talking well-nigh accessing the network, this refers solely to SPNEGO (Negotiate), NTLM and Kerberos and not to whatsoever other authentication machinery. For example, processing running as LocalService tin can even so access the internet.

The general outcome with running as a standard out of the box account is that if you modify whatsoever of the default permissions you're expanding the prepare of things everything running as that account can do. So if you grant DBO to a database, non only can your service running as Local Service or Network Service admission that database merely everything else running as those accounts can likewise. If every programmer does this the computer will accept a service account that has permissions to do practically anything (more specifically the superset of all of the different boosted privileges granted to that account).

Information technology is always preferable from a security perspective to run every bit your own service business relationship that has precisely the permissions you need to do what your service does and zilch else. Nonetheless, the toll of this arroyo is setting upwards your service account, and managing the countersign. It's a balancing act that each application needs to manage.

In your specific case, the issue that y'all are probably seeing is that the the DCOM or COM+ activation is limited to a given set of accounts. In Windows XP SP2, Windows Server 2003, and above the Activation permission was restricted significantly. You should use the Component Services MMC snapin to examine your specific COM object and come across the activation permissions. If you lot're not accessing anything on the network as the machine account you should seriously consider using Local Service (non Local Organization which is basically the operating arrangement).

In Windows Server 2003 you cannot run a scheduled chore equally

• NT_AUTHORITY\LocalService (aka the Local Service account), or
• NT AUTHORITY\NetworkService (aka the Network Service account).

That capability merely was added with Task Scheduler two.0, which only exists in Windows Vista/Windows Server 2008 and newer.

A service running as NetworkService presents the machine credentials on the network. This means that if your reckoner was called mango, it would present as the automobile account MANGO$:
