can u help me out as soon as possible. my prob is that after i created some virtual domains in the apache web server. i tried 2 restart the httpd service, but it failed. so i thought of restarting the system.but, while booting, while starting the services, it stops at "starting httpd service". so the system is not getting loaded fully.

I think every service will eventually time out (although some have timeout time as large as 10 mins) so while it may be annoying, there is no reason it should keep your system from booting altogether.
