Troubleshooting 51

TCP/IP Direct Connect

If TCP/IP Direct Connect is configured with a link type of HSAS or MPCPTP,
please refer to the section titled “Troubleshooting” in the “MPC+ for Windows NT
Installation Guide”.

In Windows 2000 the easiest way to tell if TCP/IP Direct Connect has failed to
activate is to look at the system’s console(Figure 6-4). Since TCP/IP Direct Connect
is seen as a LAN connection by Windows 2000, a disconnect icon will display if
TCP/IP Direct Connect is not active.

Figure 6-4. Windows 2000 Console

If TCP/IP Direct Connect fails to activate using a Channel-to-Channel (CTC) link
type, here are some suggestions of things to look at:

1. Verify that the Mainframe IP address specified in the TCP/IP Direct Connect

Properties screen (Figure 6-5) matches the IP address assigned as the Home
address in the TCP/IP Profile on the mainframe (Figure 6-6).
