Handy bit of PowerShell my bestest ever friend wrote to check DNS accross domain controllers:
#do dns servers agree for dns
$results = $null
$results = @()
$DNSServers = Get-ADDomainController -Filter *
$hostname = Read-Host('enter dns record to check')
foreach ($DNSServer in $DNSServers)
{
$dnsrecord = Resolve-DnsName -Name $hostname -Server $DNSServer.HostName -Type A
$result = New-Object psobject -Property @{
dnsserver = $DNSServer.Name
hostname = $dnsrecord.name
IPAddress = $dnsrecord.ipaddress
}
$results += $result
}
$results | select hostname,ipaddress,dnsserver | sort ipaddress
Man, that guy sounds like a douche. You need better friends. My bestest ever friend skinned me up a fatty!
