Passing data in the variable while doing invoke-vmscript

[vin01]

I have data in $dnsserver variable but while doing invoke-vmscript I can't able to pass the data inside the guest os. How to do it?

$dnsserver
$dnsserverinstall= @'
Install-WindowsFeature  DNS -includeManagementTools
Add-DnsServerPrimaryZone -Name $dnsserver.Sitename -ZoneFile $dnsserver.Sitename
Add-DnsServerPrimaryZone -NetworkId $dnsserver.IP -ZoneFile  $dnsserver.Sitename
Add-DnsServerResourceRecordA -Name $dnsserver.VMName -IPv4Address $dnsserver.IP -ZoneName $dnsserver.Sitename -CreatePtr
'@
Invoke-VMScript -VM 'LIBPRO02' -GuestUser 'administrator' -GuestPassword 'password' -ScriptType Powershell -ScriptText $dnsserverinstall

Error:

Use the ExpandString method.
See alse my Here strings and the ExpandString method dive.

$dnsserverinstall= @' 

Install-WindowsFeature  DNS -includeManagementTools 

Add-DnsServerPrimaryZone -Name $dnsserver.Sitename -ZoneFile $dnsserver.Sitename 

Add-DnsServerPrimaryZone -NetworkId $dnsserver.IP -ZoneFile  $dnsserver.Sitename 

Add-DnsServerResourceRecordA -Name $dnsserver.VMName -IPv4Address $dnsserver.IP -ZoneName $dnsserver.Sitename -CreatePtr 

'@

$dnsserverinstallSub = $ExecutionContext.InvokeCommand.ExpandString($dnsserverinstall) 

Invoke-VMScript -VM 'LIBPRO02' -GuestUser 'administrator' -GuestPassword 'password' -ScriptType Powershell -ScriptText $dnsserverinstallSub

Hello LucD. This is not working for me!

when I executed this

$dnsserverinstallSub = $ExecutionContext.InvokeCommand.ExpandString($dnsserverinstall) 

$dnsserverinstallSub

$dnsserver contains multiple values. How to select exact value like ($dnsserver.Sitename =LIBPOC.abc.COM)

[LucD · Accepted solution]

In that case, try like this

$dnsserverinstall= @'

Install-WindowsFeature  DNS -includeManagementTools

Add-DnsServerPrimaryZone -Name $($dnsserver.Sitename) -ZoneFile $($dnsserver.Sitename)

Add-DnsServerPrimaryZone -NetworkId $($dnsserver.IP) -ZoneFile  $($dnsserver.Sitename)

Add-DnsServerResourceRecordA -Name $($dnsserver.VMName) -IPv4Address $($dnsserver.IP) -ZoneName $($dnsserver.Sitename) -CreatePtr

'@

$dnsserverinstallSub = $ExecutionContext.InvokeCommand.ExpandString($dnsserverinstall)

Invoke-VMScript -VM 'LIBPRO02' -GuestUser 'administrator' -GuestPassword 'password' -ScriptType Powershell -ScriptText $dnsserverinstallSub

Superb Its working

One last question.

With this script I can able to configure DNS inside the guest OS.

After DNS is configured I need to create host records.to achieve this I am importing a list of vmnames with required info from a csv ($inputfile) but unable to create host records.

$inputfile=Import-Csv -Path 'C:\Users\vk185112\Desktop\answerfilecsv.csv' -UseCulture
$dnsserver
$dnsserverinstall= @'
$inputfile
Install-WindowsFeature  DNS -includeManagementTools
Add-DnsServerPrimaryZone -Name $($dnsserver.Sitename) -ZoneFile $($dnsserver.Sitename)
Add-DnsServerPrimaryZone -NetworkId $($dnsserver.IP) -ZoneFile  $($dnsserver.Sitename)
foreach($dnsrecords in $inputfile){
Add-DnsServerResourceRecordA -Name $($dnsrecords.VMName) -IPv4Address $($dnsrecords.IP) -ZoneName $($dnsrecords.Sitename) -CreatePtr
}
'@
$dnsserverinstallSub = $ExecutionContext.InvokeCommand.ExpandString($dnsserverinstall)
Invoke-VMScript -VM 'VM1' -GuestUser 'administrator' -GuestPassword 'Paswd' -ScriptType Powershell -ScriptText $dnsserverinstallSub

I think the best way to do this would be in 2 stages.

First install and setup the DNS server and zone.

Then create the A- and PRT-records.

Something like this

$dnsserverinstall= @' 

Install-WindowsFeature  DNS -includeManagementTools 

Add-DnsServerPrimaryZone -Name $($dnsserver.Sitename) -ZoneFile $($dnsserver.Sitename) 

Add-DnsServerPrimaryZone -NetworkId $($dnsserver.IP) -ZoneFile  $($dnsserver.Sitename) 

'@

$dnsserverinstallSub = $ExecutionContext.InvokeCommand.ExpandString($dnsserverinstall) 

Invoke-VMScript -VM 'VM1' -GuestUser 'administrator' -GuestPassword 'Paswd' -ScriptType Powershell -ScriptText $dnsserverinstallSub

$addRecord = @'

Add-DnsServerResourceRecordA -Name $($dnsrecords.VMName) -IPv4Address $($dnsrecords.IP) -ZoneName $($dnsrecords.Sitename) -CreatePtr 

'@

$inputfile = Import-Csv -Path 'C:\Users\vk185112\Desktop\answerfilecsv.csv' -UseCulture 

foreach($dnsrecords in $inputfile){ 

    $addRecordSub = $ExecutionContext.InvokeCommand.ExpandString($addRecord) 

    Invoke-VMScript -VM 'VM1' -GuestUser 'administrator' -GuestPassword 'Paswd' -ScriptType Powershell -ScriptText $addRecordSub

}

Yeah. This looks better way then earlier. Thanks for your suggestion. 

[vin01]

The corresponding PTR record is not creating. What could be the issue?

I am suspecting the reverse lookup zone is created wrongly.

Add-DnsServerPrimaryZone -NetworkId 153.77.115.194 -ZoneFile  LIBPOC.Test.COM

[LucD]

Is the reverse lookup zone created correctly?

[vin01]

No Its creating Like this.

Its should be like this right '115.77.153.in-addr.arpa'

[LucD]

Try doing the creation of the reverse lookup zone as

Add-DnsServerPrimaryZone -NetworkId "$($dnsserver.IP.Split('.')[0..2] -join '.').0/24" -ReplicationScope Domain

[vin01]

I can able to create like this.

Add-DnsServerPrimaryZone -NetworkId "$($dnsserver.IP.Split('.')[0..2] -join '.').0/24" -ZoneFile $($dnsserver.Sitename)

Thanks LucD for all your support
