Hello,

I'm currently writing scripts to manage our public DNS Server but i'm now blocking on a script to delete mx record.

let's say i have a domain contoso.com

i have 2 mx Records for contoso.com

one with preference 10 pointing on mail1.contoso.com

and one with preference 20 pointing on mail2.contoso.com

if i use this command line :

Remove-DnsServerResourceRecord -ZoneName "contoso.com" -RRType "MX" -Name "@"  -Force

i can delete the two MX records at once

But i would like to be able to choose witch MX Record i want to delete.

i tried this command to delete the second MX record:

Remove-DnsServerResourceRecord -ZoneName "contoso.com" -RRType "MX" -Name "@" -RecordData "mail2.contoso.com"  -Force

but it ends with an error 

InputObject for resource record has an invalid value. Failed to remove the resource record on dns1.contoso.com server. Please check extended error for additional details.
    + CategoryInfo          : InvalidData: (dns1.contoso.com:root/Microsoft/...rResourceRecord) [Remove-DnsServerResourceRecord], CimException
    + FullyQualifiedErrorId : WIN32 13,Remove-DnsServerResourceRecord
    + PSComputerName        : 10.0.0.10

has anyone an idea that could help ?

Thank you 

StephaneDe

    Remove-DnsServerResourceRecord -ZoneName contoso.com
