Windows 2003 gethostbyaddr is not resolving IP to host name

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.

You should not be using a hosts file at all.  You need to set up your DNS with proper forward and reverse lookup zones.  The reverse lookup zone resolves an iP address back to it's name.

I do not have control on the DNS, locally we all use the hosts file to resolve.

Sounds like your DNS person needs to get on the ball. Servers show be in DNS with both a forward nd reverse entry.  I've not played with the host file for sometime.  Have you tried a reverse entry with the IP address then the server name.

Example:
ServerName     192.168.1.45
192.168.1.45    ServerName


From what I remember it should resolve.
