6.8 Compaq Distributed Computing Environment (DCE) for

OpenVMS

This section contains important release notes for existing users of Compaq

Distributed Computing Environment (DCE) for OpenVMS VAX and OpenVMS

Alpha.

Remote procedure call (RPC) functionality was integrated into the operating

system beginning with OpenVMS Version 7.2. As of OpenVMS Version 7.2-1,

NT Lan Manager (NTLM) security has been available in RPC calls. For more

information about RPC functionality, refer to the Compaq DCE for OpenVMS

VAX and OpenVMS Alpha Reference Guide.

Caution

Do not install Compaq DCE for OpenVMS Version 1.4 on OpenVMS

Version 7.2 or higher. Doing so will overwrite the new RPC ﬁles with

those from Version 1.4. This problem does not occur with Compaq DCE

for OpenVMS Version 1.5 or Version 3.0.

6.8.1 DCE System Management Command Procedure

V7.3

With the update of the DCE RPC ﬁles in OpenVMS Version 7.2-1, the following

changes have been made to the DCE system management command procedure

(SYS$MANAGER:DCE$SETUP.COM):

• DCE$SETUP once again stops the RPC daemon when shutting down DCE,

although SYS$MANAGER:DCE$RPC_SHUTDOWN.COM may still be called

in place of DCE$SETUP if DCE is being used in RPC-only mode.

• DCE components can no longer be started, stopped, or conﬁgured without

shutting down the RPC daemon.

6.8.2 NTLM Authenticated RPC Functionality Now Available

V7.3

The new authenticated RPC functionality in DCE for OpenVMS Version 3.0,

including impersonation and authentication with NT Lan Manager (NTLM)

protocol, is included as of OpenVMS Version 7.2-1.

The Compaq Distributed Computing Environment for OpenVMS VAX and

OpenVMS Alpha documentation that ships with OpenVMS Version 7.2-1 and

Version 7.3 provides information about using NTLM.
