This network card is DHCP-enabled

[This topic is intended to address a specific issue called out by the Exchange Server Analyzer Tool. You should apply it only to systems that have had the Exchange Server Analyzer Tool run against them and are experiencing that specific issue. The Exchange Server Analyzer Tool, available as a free download, remotely collects configuration data from each server in the topology and automatically analyzes the data. The resulting report details important configuration issues, potential problems, and nondefault product settings. By following these recommendations, you can achieve better performance, scalability, reliability, and uptime. For more information about the tool or to download the latest versions, see "Microsoft Exchange Analyzers" at http://go.microsoft.com/fwlink/?linkid=34707.]

The Microsoft® Exchange Server Analyzer Tool queries the Win32_NetworkAdapterConfiguration Microsoft Windows® Management Instrumentation (WMI) class to determine whether a value is set for the DHCPEnabled property. If the value for this property on an Exchange server is one (1), an error is displayed.

Running Exchange on a DHCP-enabled network card is a supported configuration. However, this configuration is not recommended. Running Exchange on DHCP-enabled computers is not a best practice because if the DHCP service fails or is interrupted, Exchange may stop delivering mail or may otherwise fail.

It is recommended that you configure all computers running Exchange to use static IP addresses.
