Powershell script to run dcdiag against all DCs in domain

Hello,

Hopefully this is a nice quick and easy answer, I am trying to wirte a script that will run a dcdiag against all DCs in my domain.

DCDiag /a only runs the dcdiag against all DCs in my site, but I have multiple sites

DCDiag /e runs dcdiag against all DCs in the Enterprise, the problem is that my domain is a child domain, and this test runs against every DC in the Entire Forest.

If I run a DCDiag /s:servername I can only pipe one server in per command.

Is there a way to run DCDiag against all DCs in my domain?

Try

Get-ADDomainController -Filter * | ForEach-Object {DCDiag /s:$($_.Name)}

Open in new window

I tried this

Get-adDomainController -Filter * | ForEach-Object {DCDiag}

Open in new window

Which does return results, but only result for the local domain controller I am running the script from, its weird because it returns the same amount of time as there are DCs

EG -

Get-adDomainController -Filter *

Open in new window

Returns 12 Domain Controllers:

So what I run the script it gives me the results for the local domain controller 12 times, instead and runnign the DCDiag against each DC.

I'm not familiar with the specifics of these cmdlets, but it seems to me that inside the {} of ForEach-Object you're going to need to specify the specific information of the domain controller to it, for example

Get-adDomainController -Filter * | ForEach-Object {DCDiag /s:$_.Name}

I'm not sure Name is the right property

Thanks for you reply

Hhhmm closer I think but I dont think powershell likes the $ straight after /s:

As I get this error

The host Microsoft.ActiveDirectory.Management.ADDomainController.HostName could not be resolved to an
IP address.  Check the DNS server, DHCP, server name, etc

Open in new window

It looks to me like it is trying to run a DCDiag against a erver called $_.Name

Well you can see if it's expanding that correctly like

Get-adDomainController -Filter * | ForEach-Object {Write-Host $_.Name; DCDiag /s:$_.Name}

but again I don't have the cmdlets for active directory to know if name is the right property

If you do Get-adDomainController - Filter * | ft -Autosize

the column names should give you a clue

Thanks again

Name will bring up the server name so I think that is correct what I dont think it likes is

/s:$

If I type that in the Powershell ISE it sees it as one long string rather than 2 seperate things.

Using your command above the host name is wrote to the screen but I get the same error

The host Microsoft.ActiveDirectory.Management.ADDomainController.Name could not be resolved to an
IP address.  Check the DNS server, DHCP, server name, etc

Open in new window

Because I think it still doesnt like /s:$_.Name
