1.4 Relationship to Other Protocols
The W32Time Remote Protocol uses RPC over Server Message Block (SMB), as specified in [MS-SMB], as its transport. The W32Time Remote Protocol is commonly used to control and monitor a time service that implements the NTP Authentication Extensions [MS-SNTP].
The following diagram illustrates the W32Time Remote Protocol client-side relationships.
Figure 1: Client-side protocol relationships
The following diagram illustrates the W32Time Remote Protocol server-side relationships. The W32Time Remote Protocol server-side protocol requires that a client and server implementation of NTP Authentication Extensions [MS-SNTP] be co-located on the same machine as the W32Time Remote Protocol server implementation (see section 3.2.1 for details).
