Greg,
Oops! forgot the 'sh' I now get this:
[C:\programs\apache24\bin]sh apachectl -k stop
apachectl: 101: apachectl: /apache24/bin/httpd: not found
Definitely something not right...
EDIT: after editing apachectl to have the correct HTTPD directory listed, if I try 'sh apachectl -f /Programs/apache24/conf/httpd.conf -k stop' I get an 'killed by SIGSEGV' exceptq trap file...
Regards,
