Description

On Windows, the following error message is displayed when you start Enterprise Server v3 Prelude using the server adapter within Eclipse:

Please stop the server process using the same port as the one used
by the Application Server. A server process is already running on this port
but we cannot determine if it's a GlassFish
process (lack of info or credentials)

The message does not list which port is blocked by a server process, making it difficult to locate the blocking process. Obvious candidates such 4848 or 8080 are not blocked, according to TCP View.
