Chapter 7 Troubleshooting the System 167

5. Reconnect the target modem to the debug port on the target computer (or

restart the target computer in debug mode).

6. Use the host computer to dial into the target modem.

[Parity Error] Message

This message is displayed on the host computer if the baud rates are too high to

sustain a reliable connection. The following steps resolve this problem:

1. Force the baud rate of both modems to 9600 bps. Consult your modem

documentation for the initialization string(s) that sets the DTE and DCE rates

to 9600 bps. For U.S. Robotics modems, this command is AT&N6.

2. Add the /baudrate=9600 option to Boot.ini. This sets the baud rate on the

debug COM port to 9600 bps. Always set remote debug configurations for this

option.

3. Change the modem make and model on the target computer. If possible, use

the same make and model modem as the Citrix representative. Identical

modems appear to have a higher remote debug success rate versus modems

from different manufacturers.

5. Conduct a loopback test to isolate the network. Install the ICA Win32 Client

on the MetaFrame server and make an IPX connection back to the MetaFrame

server. If the loopback test passes, verify that ICA connections on the same

network segment as the MetaFrame server can connect. If clients on the same

network segment can connect but clients on other segments cannot connect,

there is a problem with the router configuration or cabling.

6. Install the most current ICA Client.

7. Install the most current network interface card (NIC) drivers on the client and

server machines.

8. Remove and reinstall the NWlink IPX service.

9. Use Event Viewer to check for connection-related error messages.

10. If the problem persists, create a debug trace for the ICA Client connection.
