The server initialization begins with the procedures described in [RFC1305] section 22.214.171.124, "Initialization Procedure". It is followed by the following initialization steps:
The server MAY set the sys.refid element to "VMTP" <21> If the sys.refid element is set to "VMTP" then:
The sys.stratum element SHOULD<22> be set to one greater than the stratum of its virtualization host.
If the sys.refid element is set to "LOCL" as defined in [RFC2030] section 4 then:
If the AnnounceFlags element is set to Reliable_Timeserv_Announce_Yes, then the sys.stratum element MUST be set to 1.
If the AnnounceFlags element is set to Reliable_Timeserv_Announce_Auto and the Trusted Domain element is NULL, then the server MUST execute the DsRolerGetPrimaryDomainInformation method defined in [MS-DSSP] section 126.96.36.199, using an InfoLevel value of DsRolePrimaryDomainInfoBasic. If the MachineRole field of the DSROLER_PRIMARY_DOMAIN_INFO_BASIC structure that is returned has a value of DsRole_RolePrimaryDomainController, then the sys.stratum element MUST be set to 1.
The sys.refid and sys.stratum elements are defined in [RFC1305] section 3.2.1, "Common Variables".
All abstract data model elements are configured by the server either during initialization or when it is informed of a configuration change through Service Control Manager (section 3.2.4).
