Configure A Wireless Ap As An Nps Radius Client
You can use this procedure to configure an AP, also known as a network access server , as a Remote Authentication Dial-In User Service client by using the NPS snap-in.
Important
Client computers, such as wireless portable computers and other computers running client operating systems, are not RADIUS clients. RADIUS clients are network access serversââ¬âsuch as wireless access points, 802.1X-capable switches, virtual private network servers, and dial-up serversââ¬âbecause they use the RADIUS protocol to communicate with RADIUS servers such as NPSs.
Membership in Domain Admins, or equivalent, is the minimum required to complete this procedure.
To add a network access server as a RADIUS client in NPS
On your NPS, in Server Manager, click Tools, and then click Network Policy Server. The NPS snap-in opens.
In the NPS snap-in, double-click RADIUS Clients and Servers. Right-click RADIUS Clients, and then click New.
In New RADIUS Client, verify that the Enable this RADIUS client check box is selected.
In New RADIUS Client, in Friendly name, type a display name for the wireless access point.
For example, if you want to add a wireless access point named AP-01, type AP-01.
In New RADIUS Client, in , do one of the following:
To manually configure a RADIUS shared secret, select Manual, and then in , type the strong password that is also entered on the NAS. Retype the shared secret in Confirm shared secret.
Register Nps In Active Directory Domain Services
You can use this procedure to register a server running Network Policy Server in Active Directory Domain Services in the domain where the NPS is a member. For NPSs to be granted permission to read the dial-in properties of user accounts during the authorization process, each NPS must be registered in ADÃ DS. Registering an NPS adds the server to the RAS and IAS Servers security group in ADÃ DS.
Note
You can install NPS on a domain controller or on a dedicated server. Run the following Windows PowerShell command to install NPS if you have not yet done so:
Install-WindowsFeature NPAS -IncludeManagementTools
Membership in Domain Admins, or equivalent, is the minimum required to complete this procedure.
To register an NPS in its default domain
On your NPS, in Server Manager, click Tools, and then click Network Policy Server. The NPS snap-in opens.
Right-click NPS , and then click Register Server in Active Directory. The Network Policy Server dialog box opens.
In Network Policy Server, click OK, and then click OK again.
Juice Up Your Wifi Security With Radius
The best way to increase the security of the WiFi network is to have each user uniquely log into the network. This is generally how it is handled with wired networks. For wireless networks, the process is to leverage RADIUS servers and protocols to send credentials from the WAP to the directory service. The RADIUS server is the intermediary to connect the WiFi network to the directory. While this process is understood by many IT admins, it is a painful challenge to manage all of these components.

Who Owns A Domain Name
A domain name is legally owned by a domain registrant. Whenever someone registers a domain name, the registrar will gather the registrants personal information and submit it to the WHOIS directory.With that in mind, if you register a domain name, you automatically become the registrant and will continue being so as long as you renew the fees.

Positives And Negatives Of Wireless Networks
Wireless networks are now the norm. Users are able to be more productive and mobile with WiFi. IT organizations have an easier time deploying network infrastructure because there are fewer cables. Also, it is more cost effective to deploy.
As you might expect, there are some negatives along with all of these positives. The primary negative is security. WiFi networks are available outside the building, so it is critical that IT organizations lock down their WiFi. Unfortunately, most organizations simply leverage the shared passphrase as their security mechanism. Of course, when somebody leaves they still have the passphrase, which can be passed around easily. The minimal security of WAPs today also makes it easy for hackers to break the passphrase.
Other Domain Name Types
While the above-mentioned domain name categories are the most frequent, there are other variations that you can run into.
Second-Level Domains
Youve probably seen these domain names before. Were talking about a domain that sits directly below a top-level domain name. Were not going to get too technical here because its easier to show with examples, particularly when it comes to country codes.
For example, British companies occasionally use .co.uk instead of .com, and its a perfect example of a second-level domain. Another second-level domain is .gov.uk, which is often used by governmental institutions, and .ac.uk, which is used by academic institutions and universities.
Subdomains
Subdomains are useful because they dont require webmasters to purchase an additional domain name to create divisions within their site. Instead, theyre able to create a subdomain that effectively points to a specific directory on the server. This can be super useful for campaign sites and other types of web content that should be kept separate from the main site.
For example, Facebook uses developers.facebook.com to provide specific information for web and app developers who want to use the Facebook API. Another great example is support.google.com
Free Domains
There are also free domain names that you can get from different website builders such as WordPress.com, Squarespace, Weebly, etc.

Whats In A Domain Name
Domain names function on the Internet in a manner similar to a physical address in the physical world. Each part of the domain name provides specific information. These pieces of information enable web browsers to locate the web page. The naming system is closely regulated in order to prevent confusion or duplicate addresses. As demand increased exponentially, a new Internet Protocol version, or IPv6, was created to expand the number of domain names available.

Domain Names And Ip Addresses
An Internet Protocol, or IP, address is different than a domain name. The IP address is an actual set of numerical instructions. It communicates exact information about the address in a way that is useful to the computer but makes no sense to humans. The domain name functions as a link to the IP address. Links do not contain actual information, but they do point to the place where the IP address information resides. It is convenient to think of IP addresses as the actual code and the domain name as a nickname for that code. A typical IP address looks like a string of numbers. It could be 232.17.43.22, for example. However, humans cannot understand or use that code. To summarize, the domain name is a part of the URL, which points to the IP address.
What Is A Port Number
To put it simply, a port number is the means through which a specific message is identified when its forwarded to a server. As there are 65,535 ports for each IP address, a specific designation would refer to one or several of those thousands of ports. Depending upon the service type, the message will either be associated with a TCP or a UDP port.

Specify Wireless Ap Channel Frequencies
When you deploy multiple wireless APs at a single geographical site, you must configure wireless APs that have overlapping signals to use unique channel frequencies to reduce interference between wireless APs.
You can use the following guidelines to assist you in choosing channel frequencies that do not conflict with other wireless networks at the geographical location of your wireless network.
-
If there are other organizations that have offices in close proximity or in the same building as your organization, identify whether there are any wireless networks owned by those organizations. Find out both the placement and the assigned channel frequencies of their wireless AP’s, because you need to assign different channel frequencies to your AP’s and you need to determine the best location to install your AP’s.
-
Identify overlapping wireless signals on adjacent floors within your own organization. After identifying overlapping coverage areas outside and within your organization, assign channel frequencies for your wireless APs, ensuring that any two wireless APs with overlapping coverage are assigned different channel frequencies.
Tld: Top Level Domains
A top level domain is exactly what it sounds like: a type of domain name which is at the top level of the internets domain name system. There are over a thousand TLDs available but the most common include .com, .org, .net, and .edu.
The official list of TLDs is maintained by an organization called the Internet Assigned Numbers Authority and can be viewed here. IANA notes that the list of TLDs also includes ccTLDs and gTLDs, which well talk about next.

Domain Names And Urls
The universal resource locator, or URL, is an entire set of directions, and it contains extremely detailed information. The domain name is one of the pieces inside of a URL. It is also the most easily recognized part of the entire address. When computer users type a web address directly into the field at the top of their browser window, it initiates a process of locating the page requested. To do so, the instructions contained inside the URL, including the domain name, must correctly point to that location. The IP address is a numerical code that makes this possible.
Find Your Domain Host
Your domain host is typically who you bought your domain name from. If you dont remember who your domain host is, search your email archives for billing records about registration or transfer of your domain name.
Your domain host is listed on your invoice.
If you cant find your billing records, you can search for your domain host online. The Internet Corporation for Assigned Names and Numbers is a non-profit organization that collects domain information. Use the ICANN Lookup tool to find your domain host.
Domain resellers
Some domains are hosted by resellers through a separate registrar. If you cant sign in with your listed registrar or the registrar field is blank, your domain host may be a reseller.
If there is no reseller listed, contact the listed registrars support team for help.

What Does A Port Scanner Do
Basically, a port scanner probes a host or server for open ports. These applications are commonly used by administrators to verify network security policies . In fact, even hackers use port scanners to identify open ports on a host so they can exploit any vulnerabilities attributed to those open ports.
Activate Default Wireless Network Policies
This procedure describes how to activate the default Wireless Network Policies by using the Group Policy Management Editor .
Note
After you activate the Windows Vista and Later Releases version of the Wireless Network Policies or the Windowsà XP version, the version option is automatically removed from the list of options when you right-click Wireless Network Policies. This occurs because after you select a policy version, the policy is added in the details pane of the GPME when you select the Wireless Network Policies node. This state remains unless you delete the wireless policy, at which time the wireless policy version returns to the right-click menu for Wireless Network Policies in the GPME. Additionally, the wireless policies are only listed in the GPME details pane when the Wireless Network Policies node is selected.
Membership in Domain Admins, or equivalent, is the minimum required to perform this procedure.
To activate default Wireless Network Policies
Follow the previous procedure, To open or add and open a Group Policy object to open the GPME.
In the GPME, in the left pane, double-click Computer Configuration, double-click Policies, double-click Windows Settings, and then double-click Security Settings.
