The filename, directory name, or volume label syntax is incorrect.

trying to change 2012 windows DNS settings with following

 

$DC = read-host "Enter Datacenter"

 

$GuestCred = $Host.UI.PromptForCredential("Please enter admin credentials", "Enter Guest credentials", "", "")

$PrimaryDNS = Read-Host "Primary DNS: "

$SecondaryDNS = Read-Host "Secondary DNS: "

 

get-datacenter $DC | get-vm | ? {$_.NAme -notlike "*dc*" -and $_.powerstate -eq "PoweredOn"} | % {Invoke-VMScript -VM $_ -GuestCredential $GuestCred -ScriptType "bat" -ScriptText "netsh interface ip set dns ""Ethernet0"" static $PrimaryDNS && netsh interface ip add dns ""Ethernet0"" $SecondaryDNS" }

 

but keep getting following error

 

ScriptOutput
---------------------------------------------------------------------------------------------------------------------------------------------------------

i was able to use 

 

invoke-vmscript -VM $VM -scripttext {ipconfig /all}

 

this worked just fine. Also I checke the name of the ethernet name and it is correct "

[tdubb123]

I think the reason was some VM has ethernet interface labelled different

 

some as Ethernet0

some as Ethernet

some as PROD

 

any idea?

Then you would need to find the name of the interface first, and substitute that in the $code1 variable

[tdubb123]

is there way to get the variable from invoke-vmscript.?

 

$code0 = @"

$nic = (Get-NetAdapter | ? {$_.Status -eq "up"}).name

"@

 

 

 

[LucD]

Try like this

 

$code0 = @"
(Get-NetAdapter | ? {$_.Status -eq "up"}).name
"@
$nic = (Invoke-VMScript -VM $_ -GuestCredential $GuestCred -ScriptType "PowerShell" -ScriptText $code0).ScriptOutput

kept getting 

 

ScriptOutput

I didn't notice you had "bat" as the ScriptType, I corrected it to PowerShell.
Try again

The following works for me

 

$DC = Read-Host "Enter Datacenter"

$GuestCred = $Host.UI.PromptForCredential("Please enter admin credentials", "Enter Guest credentials", "", "")
$PrimaryDNS = Read-Host "Primary DNS: "
$SecondaryDNS = Read-Host "Secondary DNS: "
$code1 = @"
netsh interface ip set dns Ethernet0 static $PrimaryDNS && netsh interface ip add dns Ethernet0 $SecondaryDNS
"@
$code2 = @'
ipconfig /all
'@
Get-Datacenter $DC | Get-VM |
Where-Object { $_.Name -notlike "*dc*" -and $_.powerstate -eq "PoweredOn" } |
ForEach-Object {
  Invoke-VMScript -VM $_ -GuestCredential $GuestCred -ScriptType "bat" -ScriptText $code1
  # Verify setting
  Invoke-VMScript -VM $_ -GuestCredential $GuestCred -ScriptType "bat" -ScriptText $code2
}
