Check Remote Servers Connectivity using PowerShell – Script

For the scripter or System admins, many times they need to deploy script on the remote servers. However, there is always a fear if the remote servers have active connectivity and ports are proper so the script wouldn’t fail.

Script will run the below checks.

• Test remote connectivity ICMP port.
• Test WINRM Connectivity
• Test WINRM HTTP port: 5985 , HTTPS port: 5986
• Remote Firewall profile (Domain, Public and Private)
• Execution Policy

Script:

function check-RemoteConnectivity {
    param(
        [parameter(Mandatory = $true, ValueFromPipeline = $true)]
        [String[]]$servers
    )


    Begin {
        Write-Verbose "`nRunning Connection Check "
