Windows Servers

1. Ensure Telnet Client is Installed:
   • Go to Control Panel > Programs > Turn Windows features on or off > Telnet Client.
   • Check the box for "Telnet Client" and click "OK."
2. Run the Telnet Command:
   • Open Command Prompt and execute:
     bash

     Copy code

     telnet TargetServer PortNumber
   • Result:
     • If the screen goes blank, the port is open.
     • If a connection error appears, the port is closed or blocked.

• The result will indicate whether the port is open or closed.

1. Using Robocopy (Built-in Tool)

• Schedule a task to run Robocopy for syncing directories.

• /MIR: Mirrors the source and destination (deletes extra files in the destination).
• /Z: Enables restartable mode.
• /LOG: Saves the output to a log file.

1. Open Task Scheduler on one server.
2. Create a new task and add the robocopy command in the "Action" tab.
3. Set the trigger for the desired schedule (e.g., daily or hourly).

2. Using PowerShell with Scheduled Tasks

• Write a PowerShell script to sync files and use Task Scheduler to automate.

3. Third-Party Tools

• Use tools like FreeFileSync, Resilio Sync, or GoodSync for advanced options like real-time syncing, logging, and file versioning.

Best Practices:

• Test before deployment to avoid overwriting or deleting important data.
• Ensure network and user permissions are correctly configured for access.
• Use a VPN or encryption for secure data transfers over the network.

To Check Connectivity:

1. Ping Test
   • Open Command Prompt and run:
     bash

     Copy code

     ping TargetServer
   • This checks basic connectivity and measures latency.
2. Tracert Command
   • Open Command Prompt and run:
     bash

     Copy code

     tracert TargetServer
   • This identifies network hops and highlights potential delays.
3. PowerShell Test-Connection
   • Open PowerShell and run:
     powershell

     Copy code

     Test-Connection -ComputerName TargetServer
