PowerShell - Read-Host to out-grid DC TCP/ICMP Info w/IP address resolves

Take the code and save as a named.ps1, it gets the DC's across the domain and asks for port to test, gives IP of DC's and Name, ping succeeds and tcp test succeeds reported per port

$a = Read-Host "Enter the Port For OutGrid View Across Domain"

# Get your ad domain

$DomainName = (Get-ADDomain).DNSRoot

# Get all DC's

$AllDCs = Get-ADDomainController -Filter * -Server $DomainName

# Using one-liner - Get all DC's and test connection on port 3269

(Get-ADDomainController -Filter * -Server $((Get-ADDomain).DNSRoot)).Hostname |

Foreach{Test-NetConnection -ComputerName $_ -Port $a -InformationLevel Detailed} |
