Detect rogue DHCP servers

If your clients experience network access problems due to incorrectly leased IP addresses & incorrect options, you probably have a rogue DHCP server on the network. Rogue DHCP servers are those DHCP servers that are misconfigured, unauthorized unknowingly or those that are configured with a malicious intent for network attacks.

Rogue detection tool is a GUI tool that checks if there are any rogue DHCP servers in the local subnet.

Following are the features with this tool:

  1. The tool can be run one time or can be scheduled to run at specified interval.
  2. Can be run on a specified interface by selecting one of the discovered interfaces.
  3. Retrieves all the authorized DHCP servers in the forest and displays them.
  4. Ability to validate (not Authorize in AD) a DHCP server which is not rogue and persist this information
  5. Minimize the tool, which makes it invisible. A tray icon will be present which would display the status.
  6. When you start the program, it queries the AD and lists all authorized DHCP servers.
