SYMPTOMS

In Windows XP, you run the "ipconfig /displaydns" command to display the contents 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.

CAUSE

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.

RESOLUTION

To resolve this problem, install the following hotfix and the hotfix for KB934401. For more information, click the following article number to view the article in the Microsoft Knowledge Base:
