Troubleshooting tools to use with IAS

To help you gather information to troubleshoot problems with IAS, the following troubleshooting tools are available:

  • IAS event logging and Event Viewer

  • Network Monitor

  • System Monitor counters

  • SNMP Service

IAS event logging and Event Viewer

Use Event Viewer to obtain information about hardware and software problems and to monitor all security events--including informational, warning, and error events.

To troubleshoot IAS authentication attempts in the system event log, enable event logging for IAS. Viewing the authentication attempts in this log is useful in troubleshooting remote access policies. When you have multiple remote access policies configured, you can use the system event log to determine the name of the remote access policy that either accepted or rejected the connection attempt. Enabling IAS event logging and reading the text of IAS authentication events in the system event log is the most useful tool for troubleshooting failed IAS authentications. For more information, see Event logging for IAS.

Network Monitor

You can use Network Monitor, available in Windows Server 2003, Standard Edition; Windows Server 2003, Enterprise Edition, or Windows Server 2003, Datacenter Edition; or a commercial packet analyzer (also known as a network sniffer), to capture and view RADIUS authentication and accounting messages that are sent to and from the IAS server. Network Monitor includes a RADIUS parser, which you can use to view the attributes of a RADIUS message and troubleshoot connection issues.

For more information, see Network Monitor.

System Monitor counters

You can use Performance console overview to monitor the resource use of specific components and program processes. With System Monitor, you can use charts and reports to determine how efficiently your server uses IAS and both identify and troubleshoot potential problems.

You can use System Monitor to monitor the following IAS-related performance objects:

  • IAS Accounting Client

  • IAS Accounting server

  • IAS Authentication Client

  • IAS Authentication server

SNMP Service

You can use SNMP to monitor status information for your IAS server. IAS supports the RADIUS Authentication server MIB (as specified in RFC 2619) and the RADIUS Accounting server MIB (as specified in RFC 2621).
