  • Dropping DNS Entries

    Hi. We run a Windows 2000 domain. All of a sudden, DNS entries are dropping like flies. We increased our scavening times, but this has not helped. We checked our logs, but could not find anything significant. Any suggestions on a tool to use or something else we can monitor? Thanks!

The IP and domain lookup in question appear to be related to malware and they are being blocked,...
