Apache - AH00341: winnt_accept: Asynchronous AcceptEx failed

Question

I'm using apache for my system. Recently I received complaints from the client saying they unable to access the system. I remote to my server and checks my Apache and its working fine. I try to launch the localhost ant it working fine also. I could not find any issue and have no other go rather than restarted my apache. After restarted the system back to normal. After some digging in the log files, I found something there.

The specified network name is no longer available. : AH00341: winnt_accept: Asynchronous AcceptEx failed.

I try to google it out but unable to find the solution for this. Is there anyone face the same issue earlier and solve this. Below is my server details:

Window Server 2008 R2 Standard
Apache 2.4
Using SSL Connection

Any advice or reference links for the issue is highly appreciated.

This usually occurs due to some software or driver inserting itself into the Windows network stack. You can skip over these layers by adding this to 2.4:

AcceptFilter https none

AcceptFilter http none

In older releases, this was turned off "Win32DisableAcceptEX".

after adding Win32DisableAcceptEX to the httpd.conf file, the syntax validation is failing; I was trying to follow options given in the article: could any one please provide further info? – Castalia

I confirm that it works and it's explained in the documentation: wiki.apache.org/httpd/AcceptExFailed – Encincture

This did the trick for me. I was experiencing really odd server freezes on my developer test system, where Apache started refusing to handle any requests until certain other requests completed - honestly had no clue how it was happening until I spotted this error in the log.
