Web Server on XP

[David Jones]

WSAEADDRINUSE is the error message, not the server.
Have you ever installed a web server (like IIS or Apache)
on this machine before?

You can find the process causing it by issuing the
command 'netstat -ano' from a command prompt. Look for
the 0.0.0.0:80 line and find the associated PID. Then
run the command 'tasklist /svc' and find the PID that
matches - that will tell you what program is using the
port.

My mistake, that particular command only works on Pro it
looks like. You can do the same thing by opening Task
Manager, clicking the Processes tab, then clicking the
View menu and selecting 'Select Columns' Check the box
for PID (process identifier) and you'll get the same
result.
