When starting a RADIUS validation server from the VIP Enterprise Gateway console the following error is displayed.
First, verify that the port is not already being used by another validation server. If it is not, use the netstat command-line utility to check if anything else might be using the port.
If the port is not currently bound to another service on the server it is possible that the validation server did not stop completely. This issue can be resolved using the following steps.
The validation server should now start again using the original port.
