I don't really know much about the error logs but, is this a fresh install or have you been changing any of Apache's settings? If so what have you changed? If it is a fresh install do you have any other programs (Such as Skype) that would be listening on port 80? –  Sour Lemon Nov 12 '11 at 16:58
    
its fresh install and 80 port is open and also free –  jayesh Nov 12 '11 at 17:01
    
What OS are you trying to run Apache on? I ask because my only other advise would apply to XP SP2. –  Sour Lemon Nov 12 '11 at 17:15
    
window xp services pack 2 –  jayesh Nov 12 '11 at 17:19
    
Ok, I posted my final suggestion as an answer - Hopefully it's what you're looking for. –  Sour Lemon Nov 12 '11 at 17:23

Try uninstalling any anti-virus and/or firewall software you have then restart Windows and try to start WAMP again. If it works try a different AV and/or firewall software combination until everything plays nice together.

From this Bugzilla entry it appears certain AV and firewall software can cause this issue on XP SP2, no mention of which ones though.

If it is not the LMHOSTS Lookup issue then there is likely something already running on the port on which Apache is trying to listen. Open a command prompt, run netstat -an and look for listening processes. Compare the port(s) listed with the Listen ports in your Apache conf.

On windows, use the command : NETSTAT.exe -an | FINDSTR.exe "LISTENING" –  djangofan Jan 17 '12 at 20:36
    
Or the simpler netstat -an | find "LISTENING" –  Dave Forgac Jan 26 '12 at 13:14
