I had problems with my Apache too. I switched off the three directives:
EnableMMAP off
EnableSendfile off
Win32DisableAcceptEx

And now everything seems to be fine. I hope I can soon switch to Linux with my Server.

I used the instructions from the main post and it solved the same problem. It works.

No! Error not only in Win32DisableAcceptEx
In most cases there is a problem in winsock driver, shipped with custom network adapter.

To fix this, simple run “netsh winsock reset”

Yes it’s caused by NOD32, if you turn Web Access Protection off, the error is not showing anymore

Does this have anything to do with Win32DisableAcceptEx or Windows sockets etc ?

[...] the link if anyone needs it winnt_accept: Asynchronous AcceptEx failed Error in Apache Log

By: Inanc

WebServer : apache 2.2
PHP: 5
Browser :IE

This is strange. I just installed phpBB3 and configured it. When I try to access the web server for the first time, no problem. However i phpBB3, when I try to post something or try to logout for examle (this has to be something related to POST function of HTML) I can’t get a response from the server for say 5 minutes, then after everything turns back to normal. In this 5 minutes I can access the server locally using localhost directive.

Before phpBB3 I did not have this problem. I also experience this problem with IE, not Mozilla or Opera.

for what it’s worth – I only get the asynchronous error message when I manually add the ‘load phpmodule’ jargon to the httpd.conf file.

Apache (2.2.4 on winxp sp2) starts fine without the PHP (5.2.3) added lines – add those lines and Apache will not start …maybe xampp would be better than a manual install of each on top of xp…..

it’s not related in any way to my ISP, I am trying to surf LOCALLY from computer where webserver is running using my localip (127.0.0.1 / localhost / 10.0.0.14, etc)

mike…

It may be cause of the port number you are using at apache server, because most of the ISP block port 80. try to change your port number in httpd.conf file from 80 to 8000 or bay be something else, and then open website
like for example

http://202.5.152.83:8000/my_site.html

Actually, it’s generaly error that caused by Eset Nod32 antivirus, Microsoft already knows about that

hmm…

this still isn’t working for me. i have an “out-of-the-box” install of xampp with localhost working great. i have checked ports, routing, av software, firewall and everything seems OK. placing Win32DisableAcceptEx in httpd.conf and restarting apache does not help.
(ie. i no longer get the AcceptEx() error, but still can’t access server externally.)

any advice?

thx!

Hello.

My name is Scott McGavern, and I host my own site using apache software on a Windows XP machine, as noted below from my System Info:

After a quick Google search inspired by the reading of my server’s Error Log, I noticed the title to this blog popped up in the results. So, I decided to comment and maybe help someone out with my experiences with this directive.

Fist, I took note that I didn’t even have the Win32DisableAcceptEx directive in my httpd.conf file. So, I did that first, then saved my work.

Then, as the article mentioned, I did go ahead and turn the EnableMMAP and EnableSendfile to the off state, re-saved my httpd.conf file, and then restarted apache.

I then got a message in the command line utility that said “[notice] Disabled use of AcceptEx() WinSock2 API”. However, apache did start rather unremarkably, and appears to be running fine.

I then re-checked the new process entry in my Error Log file, and the “[notice] Disabled use of AcceptEx() WinSock2 API” message was there, too. But, other than that, I don’t believe I’ve ever had a nicer, cleaner system re-start of my Windows XP-based apache server.

I hope this information helps.
