I have Symantec netbackup 6.5 running as a client on the Windows 2003 server. However after I edited the hosts file, the server is able to ping each other by name, but cannot resolve by IP to name.
The DNS has nslookup disabled by default. I have another server on this network running the exact configuration, but is able to use the gethostbyaddr to resolve an IP to the host name.
Called Symantec but they said it is an OS issue.
