| Description | ISA Server has encountered an error while loading the RADIUS Server List. The error was encountered while loading information for the RADIUS Server named %1. |
| Event Information | According to Microsoft Cause: This event occurs when ISA Server is unable to read the RADIUS server attributes (such as order, connection timeout, port, use msg authenticator, shared secret) from storage, or memory allocation fails, or ISA Server was unable to resolve the RADIUS server name to an IP address (i.e., GetHostByName failed). Resolution: Verify that your RADIUS Server settings are correct. If you specified the RADIUS Server as a FQDN, verify that the name can be resolved to an IP address.Check that memory resources are available. |
