Sometimes you just need to pull up a remote command prompt. I use this in most cases to verify a device is what I think it is. I just need to run a simple
hostname command on a end user device.
As the title suggests, I use PSExec to accomplish this. These days you could also go the Powershell route, but this works more consistently for me at the time of writing. This tool requires that you have admin access to the remote device. In my case I use this as a SysAdmin where we have implemented LAPS, so I will need to pass a username and password to the command. If you are already admin on the device using your current credentials, possibly a domain environment without a PAW/LAPS setup, then you can exclude -u and -p. This page also includes all available parameters.
Download PSExec, unzip, and execute a single time to accept the EULA. Now in a command prompt
cd to the folder where you unzipped PSExec.exe.
Execute the following to open a remote command prompt on a remote device
psexec \\[ip_or_hostname] cmd.exe -u [remote_device_admin] -p [remote_device_password]
Once that executes it will drop you to a standard looking command prompt. You can type
hostname to display the computer name, and it should display the remote computers hostname. Now you can run any command as if you were sitting at the device.
