Ping User-Name

HKLM\SYSTEM\CurrentControlSet\Services\IAS\Parameters

Data type	Range	Default value
REG_SZ	User name	Blank

Description

Specifies a user name (or user name pattern with variables) that the Internet Authentication Service (IAS) recognizes as a fictitious name. As a result, IAS rejects authentication requests and responds to all accounting requests from this user. Also, IAS does not record transactions involving this user in any log files.

Proxy servers implementing the Remote Authentication Dial-In User Service (RADIUS) protocol and Network Access Servers periodically send authentication and accounting requests (known as "ping requests" to verify that the server is responsive. These ping requests include fictional user names.

This entry helps IAS recognize the fictitious name or naming scheme used in ping requests. This method is likely to improve IAS performance and make the event log easier to interpret.
