Cassini service keeps crashing

Question

I'm running XP home which doesn't support IIS. Therefore i'm running Cassini.

It usually works well. How ever i've notice in the last 2 weeks it crashes. I'm guessing there is some conflict. Perhaps something i've installed recently tho i can't work out what.

How can i work what is conflicting, also i've read about running it on a different port that 80. How would i set this up? Or maybe it's something else?

thanks.

Answer 1

if you run:

netstat -a -n -o

you will get a list of what is running on each port.

This list includes the PID (process id) you can then use task manager to find which process is on port 80.
