Check the FAQ. This is a very common failure in third party junk products that install themselves into the network stack. The stack consists of the drivers you see in Control Panel - Networks - [network adapter] Properties... when look at the Networking tab of the adapter properties page, it will show you a list of network stack drivers. These might include Client for Microsoft Networks QoS Packet Scheduler File and Printer Sharing for Microsoft Networks TCP/IPv4 etc. These happen to be Microsoft drivers. Third party drivers which are incompatible with the Windows Sockets API (junk drivers) will cause Apache to fail to start up; that behavior should happen no matter which Apache httpd package you obtain from where ever. What is in your list of adapter drivers? That would help us to suggest if there is something you should uninstall. The other possibility is that a malicious driver was installed for your network stack by some trojan or malware app. In the case of that possibility, it may not show up in the list of drivers. --------------------------------------------------------------------- The official User-To-User support forum of the Apache HTTP Server Project.
