This article discusses a few symptoms where an AppleShare IP server will display IP addresses instead of the DNS name.

1. The IP Manager's "Network Info" window lists the DNS name as either Unavailable or as the IP address.
2. The user's email address is listed as user@xx.xx.xx.xx where xx.xx.xx.xx is the server's IP address.
3. On an AppleShare IP 5.x server, this failure will cause a message in the error log that Open Transport is not loaded.
4. On an AppleShare IP 6.x server, the error log will note that the reverse lookup failed, but it will still exhibit symptoms (1) and (2) above.

1. Make sure the proper name servers are listed in the TCP/IP control panel of the server.
2. Make sure the name server containing the DNS record for the server is configured properly to do reverse DNS lookups (a TCP/IP troubleshooting utility like the shareware WhatRoute or Neon software's OTTool can help determine this). If you are using MacDNS, this is done automatically when you add a permanent host.
3. If the above steps indicate everything is okay and you are still having problems, trash the TCP/IP preferences on the server and set them up again from scratch. Be sure not to change the TCP/IP setting while any of the AppleShare servers are running.
