6.4 Compaq DCE for OpenVMS

This section describes the enhancements in Compaq Distributed Computing

Environment (DCE) for OpenVMS Version 7.3.

6.4.1 Compaq DCE Remote Procedure Call (RPC)

Beginning with OpenVMS Version 7.2-1, the NT Lan Manager security in DCE

RPC is fully functional.

6.4.2 New Ethernet Device Support

If DCE RPC does not recognize the Ethernet device in your system, one new

device may be added to the table of known devices by deﬁning the system logical

DCE$IEEE_802_DEVICE to be the device name of your Ethernet device.

For example, to deﬁne a single DE500 Ethernet device, set the logical as follows:

$ DEFINE/SYSTEM DCE$IEEE_802_DEVICE EWA0
