- TITLE :Discussion of DCE CDS and RPC NSI
- PRODUCT :Windows NT
- PROD/VER:3.10
- OPER/SYS:WINDOWS
- KEYWORDS:
-
- ----------------------------------------------------------------------
- The information in this article applies to:
-
- - Microsoft Windows NT operating system, version 3.1
- - Microsoft Windows NT Advanced Server, version 3.1
- ----------------------------------------------------------------------
-
- The Microsoft remote procedure call (RPC) run-time library provides a
- set of name service APIs (all prefixed by "RpcNs") to enable RPC
- applications to access name service information. RPC servers can
- export names and associated binding information to a name service
- database through these APIs. And, using the same set of APIs, RPC
- clients can import server binding information.
-
- The RPC library implements these APIs by accessing a name service
- database through the RPC run-time interface called the name service
- interface (NSI). This interface is used to access information stored
- by various name service providers, such as the RPC Locator or the DCE
- Cell Directory Service (CDS) service.
-
- On Windows NT systems, the default RPC name service provider is the
- RPC Locator. The RPC Locator maintains a loosely consistent database
- that is strictly cached and volatile. An administrator can select an
- alternative RPC name service provider from Control Panel in the
- Network section. (DCE CDS is the only alternative supported in Windows
- NT version 3.1.)
-
- Limitations
- -----------
-
- 1. If the DCE CDS is configured as the RPC name service provider, a
- Windows NT server can export its binding information to the CDS,
- and a Windows NT client can access server binding information
- stored in the CDS. However, a DCE server has no way of exporting
- its binding information to the RPC Locator, nor can a DCE client
- access the Windows NT Locator in order to acquire server
- information.
-
- 2. The Windows NT 3.1 RPC Locator does not support groups, that is,
- the group APIs (prefixed by "RpcNsGroup").
-
- For additional information, see the Win32 SDK "RPC Programmer's Guide
- and Reference."
