When you run the "Ipconfig /displaydns" command in Windows Server 2003, the results are incomplete

In Microsoft Windows Server 2003, you run the ipconfig /displaydns command to display the content of the DNS resolver cache. However, the results are incomplete. When this problem occurs, you do not receive a message.

This problem occurs if there are too many entries in the DNS resolver cache. Typically, this problem occurs when there are too many custom entries in the Hosts file.

This problem occurs when an allocated buffer is not large enough to contain all the contents of the DNS resolver cache. When the Ipconfig.exe tool allocates memory, it does not consider the DNS entries in the Hosts file.
