MORE INFORMATION

In Windows Server 2003 and in Windows XP SP2, the Remote Procedure Call service runs under the Network Service account. In versions of Microsoft Windows earlier than Windows Server 2003 and Windows XP SP2, the Remote Procedure Call service runs under the SYSTEM account.

In Windows Server 2003 and in Windows XP SP2, calls to Windows Installer do not impersonate the SYSTEM account. Instead, calls to Windows Installer impersonate the Network Service account.
