Unable to start bootstrap server using port 2810

 I got "Caused by: com.ibm.ws.naming.distcos.NameSpaceConstructionException: Unable to start bootstrap server using port 2810. Verify that no servers or other processes are already using the bootstrap server port. Also verify that the bootstrap server is being started with a user ID which has sufficient (e.g., root, Administrator) privileges.

My Findings
1. Most of the time, a restart of the machine would solve the problem.
2. This happens when the port is being used by some other process (you can verify that using Windows netstat command)
