I was experimenting with WAMP on my laptop, not a big deal in itself, but when I rebooted the Apache server failed to start.

Event logs showed something else had already been binded to port 80.

Quick Fix was to determine which PID had it by running the following:
netstat -ano
From there you can use task manager, determine the conflicting process, kill the PID.

(If you had CYGWIN installed)
netstat -ano | grep :80
ps -Wef | grep <pid> # To determine the process
kill -9 <pid>

Not all of them mind you, but some important ones none-the-less:

• KFW_STARTJVM=N
• KFW_USE_EMBEDDED=Y
• KFW_EWAS_SERVER_PID_FILE=C:\IBM\ITM\CNPSJ\profiles\ITMProfile\logs\ITMServer\ITMServer.pid
• KFW_EWAS_STARTSERVER_SCRIPT=C:\IBM\ITM\CNPSJ\profiles\ITMProfile\bin\startServer.bat
• KFW_EWAS_STOPSERVER_SCRIPT=C:\IBM\ITM\CNPSJ\profiles\ITMProfile\bin\stopServer.bat

I verified the following by modifying all the variables in my %CANDLEHOME%\CNB\kfwenv file where numerical values like ports and max where incremented by one, and the string vlaues had _XXX_ inserted

The modified kfwenv was backed up, then I reconfigured the TEPS and ran a diff on both files, and the above variables are the resulting default values.
