To fix this problem, simply uncomment in \xampp\apache\conf\httpd.conf
the line # Win32DisableAcceptEx.
so it must appear as
The AcceptEx() is an improved Winsocks 2 produced by Apache but not working upon the Windows Home Family ( 98/ME and so on...)
Unfortunately, Windows 2000 and XP Professional are also affected.
Thus, disabling AcceptEx() is certainly the best way.
If you are running on XP Home edition, due to a bad memory management, Windows only allows 160 Kb to programs running under command.com, which is the case of Apache.
And Apache needs more memory...
How to fix it ?
Edit your config.sys file, yes Windows XP still have one (':evil:'), and add this line :
shell=c:\windows\command.com c:\windows /e:2048 /p
This will allow 2048 KB of memory for applications running on command.com
Then restart your computer.
Note : config.sys is in your root directory, commonly c:\
but it is a hidden file so you have first to make hidden files visible or use sysedit in the menu "start" "run command" and you are done.
