I have started getting this error unexpectedly. I dont believe I changed any conf files. Questions:

Are there are any temporary I can restart in the apache installation to perhaps reset its cache/tmp. I have moved everything from /xampp/tmp

I have checked to see if localhost:80 is in use, I dont think this is the case.

Please recommend steps to reset apache as I believe it is possible this is an issue caused by a orphaned PID or something of that nature as nothing has changed and I do unexpected shutdowns of my computer.

This is on Windows XP, apache httpd.exe version is 2.2.11.0

Resolved. Unexpected behavior. 443 in use and then LMHOSTS reenabled after netsh
