2.1.5 Relevant Standards

The Group Policy protocols use the following communication standards to allow interoperability with other external systems:

DNS: Specified in [RFC1034] and [RFC1035]. Used for locating the Group Policy server and determining site membership.

Lightweight Directory Access Protocol (LDAP): Specified in [RFC2251]. Used for communication with the Group Policy server to obtain GPO attribute data.

File access services: As described in [MS-FASOD]. The Windows platform chooses an SMB file access protocol to remotely access the Group Policy file share and obtain user policy information, computer policy information, and GPO version data.

SPNEGO: Specified in [MS-SPNG]. Used for authentication and authorization. See [MS-GPOL] section 1.4 for the authentication protocols that the Group Policy protocols support.
