As an administrator, your job would probably be a bit easier if you could centrally configure and distribute wireless network settings to all the computers in your Active Directory network. Fortunately, Windows supports a special Group Policy extension for Computer Configuration that lets you do just that. It’s
called the Wireless Network (IEEE 802.11) Policies extension, supported by computers running Windows Vista™, Windows® XP, Windows Server® 2003, and the next version of Windows Server, code-named "Longhorn."
Here’s how it works. Either when joining the domain, or when starting up (and on an ongoing basis after that), these operating systems automatically download the wireless settings in this Group Policy extension and apply them. You can configure wireless policies for a domain-based Group Policy object from the following node in the Group Policy Object Editor snap-in: Computer Configuration | Windows Settings | Security Settings | Wireless Network (IEEE 802.11) Policies.
