Test-DnsServer

Tests that a specified computer is a functioning DNS server.

Syntax

Parameter Set: Context
Test-DnsServer [-IPAddress] <IPAddress[]> [[-Context] <String> {DnsServer | Forwarder | RootHints} ] [-CimSession <CimSession[]> ] [-ComputerName <String> ] [-ThrottleLimit <Int32> ] [ <CommonParameters>]

Parameter Set: ZoneMaster
Test-DnsServer [-IPAddress] <IPAddress[]> -ZoneName <String> [-CimSession <CimSession[]> ] [-ComputerName <String> ] [-ThrottleLimit <Int32> ] [ <CommonParameters>]




Detailed Description

The Test-DnsServer cmdlet tests whether a computer is a functioning Domain Name System (DNS) server. The DNS server must be running Windows Server® 2008 R2 operating system or above.

When you specify a computer by its IP address only, the cmdlet tests whether the computer is a DNS server. If you also specify a zone name, the cmdlet validates that the DNS server can resolve the specified zone.

Parameters

-CimSession<CimSession[]>

Runs the cmdlet in a remote session or on a remote computer. Enter a computer name or a session object, such as the output of a New-CimSession or Get-CimSession cmdlet. The default is the current session on the local computer.
