About this tag
The IP Helper service in Windows is a system component that provides network connectivity information to applications. Discussions on WindowsForum.com cover several issues related to this service. A notable security concern is CVE-2025-21231, a Denial of Service vulnerability affecting the IP Helper service. Users also report that the service can crash when a port proxy interface is removed, and that it may cause high CPU usage after startup, especially when combined with Group Policy Client. Additionally, the IP Helper API may return blank or incomplete MIB interface information. Some users have found that disabling the IP Helper service resolves random internet disconnections, though this is not a recommended fix.
