1. Download Cygwin from the following location: https://www.cygwin.com/
   
   
2. Run the installer and follow the prompts:

• If you installed CYGWIN sshd as cyg_server user, it should be able to allow Endpoint connection as any user on the server, but that may not work always. In this situation you can try these options.
  
  1. Make sure that cyg_server account is added to Replace a process level token policy using gpedit.msc. Reference - https://technet.microsoft.com/en-us/library/dn221975(v=ws.11).aspx, https://technet.microsoft.com/en-us/library/cc957225.aspx
  2. Another option is to run CYGWIN sshd as user that you want to connect as from FlexDeploy Endpoint. Here are the steps to make that change.
     1. Make sure the account you want to connect as is Administrator account. See my example of flexuser that I used instead of cyg_server
        
     2. Stop CYGWIN sshd service. 
     3. Edit CYGWIN sshd service and make it use user that you want to connect as from FlexDeploy Endpoint. See example below.
        
     4. Click OK.
     5. Run Cygwin terminal as Administrator.
     6. Run ssh-host-config option and follow prompts.
        
     7. Now start CYGWIN sshd service.
