• Some times, we have to hide some files for particular reason like classified files and we do not want it be found by others.You just need :

• Image File or PDF File

• Files which are going to be hidden

• Archiver Application (WinRar, 7Zip, etc.)

• Command Prompt

• Now just follow this steps :

1. Compress your files and make them as archive file. In this example, I'm going to hide my test.rar file into my PDF (readme.pdf)
2.  Open your Command Prompt and run it As Administrator, direct to your files location, then type this command exclude quote marks : "copy /b readme.pdf + test.rar redme.pdf". Please adjust readme.pdf with your own PDFfile, test.rar with your own compressed file, and redme.pdf with your own new PDF name and this is up to you to give the name. After that, click ENTER button.
3.  If you did it right, you will get a New PDF files with bigger file size, because the binary codes between test.rar and readme.pdf are combined into one file is redme.pdf
   
4. To open your hidden files, you just open your archiver application, in this example is WinRar. Go to your PDF files and extract it. You will get new folder named redme and you will find your test folder inside it.

1. Connect to your server via RDP.
2. Open Windows Firewall with Advanced Security.
3. Click on Inbound Rules in the left pane.
4. In the Actions menu click on New Rule...
5. Select the Port radio button and click Next.

1. Click Next.
2. Leave the Allow the connection radio button on the Action screen selected and click Next.
3. On the Profile screen leave Domain, Private and Public checked and click Next.
4. On the Name screen give your new rule a name such as "CUSTOM RDP BLOCK".
5. Click Finish.

The new firewall rule has now been created and the IP restrictions need to be added.

Creating Your IP Restrictions

Due to our Domain Policy the IP Restrictions that will be added will block IP ranges around the IP addresses you need to leave open.  Before starting this step we suggest making a note of these IP ranges to ensure you do not restrict access to incorrect IP addresses.  

The ranges will need to be entered in ascending order. The first IP range will start at 0.0.0.0 and end at the IP address one below the IP you'd like to allow. For example, if you want to allow 60.73.200.19 your first range will be 0.0.0.0-60.73.200.18.  Your next IP range will start one IP address after the IP you want to allow and end on below the next IP you want to allow.  The final IP range will end with 255.255.255.255. 

You will need to allow the IP range of 208.88.72.0-208.88.76.255 to ensure that our tools and support department have the ability to connect to your server.

1. Right click on the new firewall rule you just created above and click properties.
2. Click on Scope tab.
3. Under the Remote IP address section select the These IP addresses option.
4. Click the Add... button.
5. Select the This IP address range radio button.
6. Enter your first IP range into the From and To boxes.

Add IP ranges to allow all the IPs required, and the IP range for our tools and support department.

Antivirus (AV)

• When using "locked" clones AV may not be required
• If you are using AV, avoid running AV scans concurrently

User Data

• Use folder redirection for My Documents potentially even to a Network Attached Storage (NAS)
• Easier to use existing file archival system, maintain multiple file versions
• Evaluate Profile Management Applications
• Turn off Outlook/thunderbird Cached Mode (VMs that are on same high speed network as your mail server don’t benefit as much from cached mode). This will save on disk space and conserve storage IOPS.
