FWIW this error happens frequently enough for Apache under windows that it's in their FAQ: ---- quote ---- Apache for Windows does not start. Error log contains this message: "[crit] (10045) The attempted operation is not supported for the type of object referenced: Parent: WSADuplicateSocket failed for socket ###". What does this mean? We have seen this problem when Apache is run on systems along with Virtual Private Networking clients like Aventail Connect. Aventail Connect is a Layered Service Provider (LSP) that inserts itself, as a "shim," between the Winsock 2 API and Window's native Winsock 2 implementation. The Aventail Connect shim does not implement WSADuplicateSocket, which is the cause of the failure. The shim is not unloaded when Aventail Connect is shut down. Once observed, the problem persists until the shim is either explicitly unloaded or the machine is rebooted. Another potential solution (not tested) is to add apache.exe to the Aventail "Connect Exclusion List". Apache is affected in a similar way by any firewall program that isn't correctly configured. Assure you exclude your Apache server ports (usually port 80) from the list of ports to block. Refer to your firewall program's documentation for the how-to. ---- end quote ---- It's probably not directly related, but there is this blurb about LSP from the page on ---- quote ---- Winsock self-healing Detailed description Winsock, Windows’ network socket facility for applications, is extensible by a mechanism known as a Layered Service Provider (LSP). Winsock LSPs are available for a wide range of useful purposes, including internet parental controls, and web content filtering. In previous versions of Windows XP, removing a malformed (also known as “buggy”) LSP could result in corruption of the Winsock catalog in the registry, potentially resulting in a loss of all network connectivity. Winsock now has the ability to self-heal after a user uninstalls such an LSP. ---- end quote ---- And finally, although it's probably not relevant, the following passage from might help track down the problem: ---- quote ---- IPv4 Inbound Connections for Applications. An application that completes a listen operation on a TCP socket or successfully binds to a UDP socket through Winsock is covered by this scenario. Examples of these applications include audio and video in MSN or Windows Messenger, or hosting a multiplayer game. For this scenario, ICF can automatically open and close ports as needed by the application. When an application that needs to listen on a port or ports is being installed by an administrator, it will need to ask the user if he/she wants to allow the application to open ports in the firewall. If the user consents to this, then the application should use the INetFwV4AuthorizedApplication API to add itself to the AuthorizedApplications collection as enabled. If the user does not consent, then the application should use the INetFwV4AuthorizedApplication API to add itself to the AuthorizedApplications collection as disabled. ---- end quote ---- Brian -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
