if you've just installed Windows Server 2008, and are trying to get connected to the internet via wireless you'll have no end of problems as it just will not see any wireless networks no matter what driver you install for your wireless card.

The reason is because Wireless is disabled by default in Windows Server 2008.

To resolve it, do as follows

in Server manager scroll down to Features Summary and click on Add Features.

启动memcached
# service memcachedstart

centos 5.7
