Hello Alan, I contacted my telecom guy and he thinks maybe there is a new or changed parameter in a TCP/IP configuration file since 5.2 thats causing this. Do you think that could be the case? Also , I found the DTCARP049I message in the Messages and Codes book but not the others. Thanks, Mike Horlick

You made quite a leap going from 5.2 to 5.4 and you picked up a lot of new functionality. The z/VM 5.4 TCP/IP Messages and Codes book includes change bars for those DTCARPxxxx messages. It's telling you that you've got another host on your LAN that is configured with the same IP address as VM TCP/IP. It didn't used to warn you; now it does.
