| .SYNOPSIS | |
| Script that will check the Replicated DNS Records between 2 DNS Servers. | |
| .DESCRIPTION | |
| ** This script will check whether the dns records on primary server exists on secondary server. | |
| ** The script will only search these record types: A, PTR, CNAME, MX, SRV, but not NS, AAAA | |
| ** You can use this script if the 2 DNS Servers are out-of-sync with each different records | |
| Example usage: | |
| Check_DNS_Records_Status_v1.1.ps1 -DestinationServer myServer2.contoso.local | |
| Author: Phyoe Wai Paing | |
| Country: Myanmar(Burma) | |
| Version : 1.0 : 03/30/2017 : Initial Release | |
| Version : 1.1 : 05/22/2023 : Removed lines that check Server 2008 or Server 2012R2 and execution for server 2008 (because it's already expired). | |
| Fixed PTR section. Thanks to Frank Dub <francois.dubois@gmail.com> for these commits. | |
| .EXAMPLE | |
| Check_DNS_Records_Status.ps1 -DestinationServer myServer2.contoso.local | |
| This will check whether the DNS records (A PTR, CANAME, MX, SRV) on the primary server (the local server the script is running) | |
| exists on the secondary server. | |
| .PARAMETER DestinationServer | |
| The secondary or destination server on which you check if the records on primary server exist. | |
| .LINK | |
