Introduction
In today's article you will learn how to remove Internet Information Services 8 (IIS8) on Windows Server.

Step 1
First of all login to your Windows Server 2012 as Administrator by entering your password. After logging in your Server Manager will open automatically, if it doesn't then open it by clicking on the first button in the task bar.

As you open the Server Manager this window will be opened:

Step 2
On the Server manager you will see that IIS is already installed.

To remove the IIS go to the Manage option on the upper right hand corner and click on "Remove Rolls and Features".

Step 3
Now a Window will be opened that will inform you that you are going to removing the section. Just click on "Next" to proceed.

After that you must select a Server from the Server Pool. Since I have only one Server in this article, my default Server is Automatically selected.

Step 4
Once you click Next you will get a list (Rolls) from which click on the Web Server (IIS).

Now click "Next", then one more Window will open that will ask for permission to remove the features.

Step 5
You can select the features that are associated with IIS to be removed.

After clicking Next you must give permission to restart the server automatically if it's considered necessary, then click on "Next".

Step 6
Click on the "Remove" button and the process will begin.

When the removal process has completed your Windows Server 2012 will be restarted; that's because earlier you had given permission to do the restart.

Step 7
After restarting it will automatically show that the removal process had completed successfully.

You can also check this on the Flag that is present on the above right hand corner. Click on the Flag and following confirmation will be shown,

Let's follow the below steps to create an FTP site.

Open IIS manager, click on Sites and then click Add FTP site,

Give a name and specify physical path that has content to be shared, click Next.

We can specify an IP address and port number on which the FTP site is  to be hosted, select No SSL option. Default port for FTP is 21. We can select a SSL certificate, if it needs to be secured. Click Next.

We can specify authentication as anonymous [no authentication needed] or basic [need to supply credentials for accessing FTP]. We can set authorization rules like read-only for anonymous users or read-write for specific users or groups. Click Finish.

We can browse FTP site using Windows Explorer, IE or command prompt or tools like FileZilla by using path like ftp://<IP/machine name>/. Since we enabled anonymous authentication, we can login by supplying user name as ftp or anonymous and password as any email address as shown below:

Let’s explore other features of FTP under Features pane of IIS Manager.

FTP Authentication: We can enable/disable anonymous or basic authentication here.
FTP Authorization Rules: We can add rules to set authorization like read-only for anonymous and read-write for specific users or groups.

FTP Current sessions: It will show details of users connected to FTP currently.

FTP Firewall settings at Server level:
Used to set data channel port number and Firewall IP Address. In general, FTP uses two ports. One is for control channel to send commands [default is 21] and other is for data channel [which can be specified here as a range and same need to be opened on Firewall as well] for sending data like file content.

FTP IPv4 Address and Domain Restrictions: Used to restrict\ allow specific IP address for accessing FTP site,

FTP Logging: It is similar to IIS logs, logs information like port number, status code, etc and used for troubleshooting.

FTP Messages: Used to set welcome and exit messages for FTP Users.

FTP Request Filtering: Used to restrict specify file extensions, URLs or commands.

FTP SSL Settings: Used to set SSL and select SSL certificate for secure FTP.

FTP User Isolation: Used to isolate users from accessing other user’s FTP site or home directory.

We can use appcmd.exe tool to create FTP site and set attributes like SSL or authentication using this tool.

Troubleshooting Tips:
    If you are unable to create FTP site, ensure that FTP service is up and running under Windows services.
    If you are getting any authentication problem, ensure that login/anonymous users have sufficient permissions like read or write on physical files.
    We can troubleshoot FTP issues using tools Wireshark and process Monitor.
    Ensure port 21 is opened on Firewall for FTP communication.

I am ending things here, I hope this article will be helpful for all.
