Many engineers not longer use the command prompt, heading straight to Powershell. However, a command prompt (also known as DOS prompt) can still be useful to perform actions quickly.
What is CMD?
To change the path in the command prompt, you can use the “cd” command followed by the directory path you want to change to.
Here are the steps:
- Open the command prompt on your Windows computer.
- Type “cd” (without quotes) and press Enter. This will display the current directory path.
- Type “cd” followed by the directory path you want to change to. For example, if you want to change to the “Documents” folder in the current user’s directory, you can type “cd C:\Users\USERNAME\Documents” (replace “USERNAME” with your actual username).
- Press Enter. You should now see the new directory path displayed in the command prompt.
Note that you can use relative or absolute paths with the “cd” command. Relative paths start from the current directory, while absolute paths start from the root directory of the drive. For example, you can type “cd ..” to move up one directory level, or “cd /” to change to the root directory of the drive.
The summary here is the traffic works and connects from our connection but fails from the users home.
This therefore clarifies that the issue is with the user’s home computer, or home router and NOT the office.
Telnet tests will save you a lot of time finding the cause of a connection problem.
If we wanted to be extra helpful, and if the user has a laptop, we could ask them to tether to their mobile phone. This is then removing the home router from the situation. If it now connects, we know it is not the machine at fault, and it is 100% the router, however if it doesn’t, we know it’s the machine that is at fault.
Some examples of when this could be used:
- We cannot load X website – of course you could just try the website in this instance.
- VPN issues.
- Our email is down – telnet theirmailserver 587
- When locking something down, and checking you cannot reach the port, the slip of trying to fix something.
