[ganapa2000]

Hi,

I am having trouble executing this command from a batch file on few of the VMs and I am getting below error.

Please help

Command

Powershell.exe -noprofile -executionpolicy bypass -command "&{start-process powershell -ArgumentList -noprofile 'Get-DnsClientServerAddress | where {$_.ServerAddresses -contains 192.168.15.5} | Set-DnsClientServerAddress -ServerAddresses 192.168.5.100,192.168.5.101' -Verbose -Confirm:$false; ipconfig /flushdns; ipconfig /flushdns; Clear-DnsClientCache; Register-DnsClient -verb RunAs}"

Error

The ArgumentList parameter expects an array with arguments.

I'm not sure what you are trying to do, but the following should get rid of the error.

$code = @'

$sProcess = @{

    FilePath = 'powershell.exe'

    ArgumentList = '-noprofile',

        '-verb runas',

        '-command "&{Get-DnsClientServerAddress | where {$_.ServerAddresses -contains 192.168.15.5} | Set-DnsClientServerAddress -ServerAddresses 192.168.5.100,192.168.5.101 -Verbose -Confirm:$false; ipconfig /flushdns; ipconfig /flushdns; Clear-DnsClientCache; Register-DnsClient}"'

}

Start-Process @sProcess

'@

powershell.exe -noprofile -executionpolicy bypass -command "&{$code}"

LucD,

I am trying to run script as .cmd file for DR Servers to update the DNS while performing the DR.

Below is the script, which I am using.

Currently I am getting the below error

C:\DR>Powershell.exe -noprofile -executionpolicy bypass "&{start-process powershell -ArgumentList '-noprofile', '-verb r

unas', '-command "  & {Get-DnsClientServerAddress   | where {$_.ServerAddresses -contains 192.168.15.5}   | Set-DnsClien

tServerAddress -ServerAddresses 192.168.5.100,192.168.5.101 -Verbose -Confirm:$false; ipconfig /flushdns; ipconfig /flus

hdns; Clear-DnsClientCache; Register-DnsClient}"' }"

The string is missing the terminator: '.

    + CategoryInfo          : ParserError: (:) [], ParentContainsErrorRecordException

    + FullyQualifiedErrorId : TerminatorExpectedAtEndOfString

'{Get-DnsClientServerAddress' is not recognized as an internal or external command,

operable program or batch file.

Did you try it like this?

powershell.exe -noprofile -executionpolicy bypass -command "&{Start-Process -FilePath powershell.exe -ArgumentList '-noprofile','-verb RunAs','-command "&{Get-DnsClientServerAddress | where {$_.ServerAddresses -contains 192.168.15.5} | Set-DnsClientServerAddress -ServerAddresses 192.168.5.100,192.168.5.101 -Verbose -Confirm:$false; ipconfig /flushdns; ipconfig /flushdns; Clear-DnsClientCache; Register-DnsClient}"'}"

[ganapa2000]

Yes LucD.

I am getting the below error

The string is missing the terminator: '.

    + CategoryInfo          : ParserError: (:) [], ParentContainsErrorRecordException

    + FullyQualifiedErrorId : TerminatorExpectedAtEndOfString

'{Get-DnsClientServerAddress' is not recognized as an internal or external command,

operable program or batch file.

It's a quoting issue.

The following seems to work for me

powershell.exe -noprofile -executionpolicy bypass -command "&{Start-Process -FilePath powershell.exe -ArgumentList '-noprofile','-command &{Get-DnsClientServerAddress | where {$_.ServerAddresses -contains 192.168.15.5} | Set-DnsClientServerAddress -ServerAddresses 192.168.5.100,192.168.5.101 -Verbose -Confirm:$false; ipconfig /flushdns; ipconfig /flushdns; Clear-DnsClientCache; Register-DnsClient}'}"

Hi LucD,

Now, I am not getting any error but DNS IP is not getting changed.

If I execute the below command directly, DNS is getting changed. but when added with script, DNS is not getting change.

Get-DnsClientServerAddress | where {$_.ServerAddresses -contains 192.168.15.5} | Set-DnsClientServerAddress -ServerAddresses 192.168.5.100,192.168.5.101 -Verbose -Confirm:$false

[LucD]

You probably need elevation for the cmdlet to work.

[ganapa2000]

Yes LucD, I tried as below also, still no luck

powershell.exe -noprofile -executionpolicy bypass -command "&{Start-Process -FilePath powershell.exe -ArgumentList '-noprofile','-command &{Get-DnsClientServerAddress | where {$_.ServerAddresses -contains 172.24.255.5} | Set-DnsClientServerAddress -ServerAddresses 172.25.255.5,172.25.255.6 -Verbose -Confirm:$false; ipconfig /flushdns; ipconfig /flushdns; Clear-DnsClientCache; Register-DnsClient -verb RunAs}'}"

all the other commands work, but first command for changing the DNS still dont work.

Your initial call to powershell.exe will not run elevated.
