launch powershell command

[valentinabombel]

hi, i have add to my vCO a powershell host, now i need to launch a command into this host machine (in my case the AD host) i need to make move a computer from original folder CN=Computers,DC=domain,DC=xxx to another organization unit ..

i use this command

Import-Module ActiveDirectory

get-adcomputer computername | Move-ADObject -TargetPath 'OU=Computers,OU=xxxxx,DC=xxxx,DC=xxx'

but i need the "computername" is a dinamic variable because the "computername" change every virtual machine i create..

i user the workflow "Invoke a powershell scripts" but i don't know if is the correct way because i have some error, but if i launch the command directly from PS in the host machine this work...

can anyonw help me to untherstand to use powershell

thanks :smileygrin:

Could you provide the error that you receive?

the log of run workflow is this.

first i use the workflow "create computer in a organization unit" and after "invoke a powershell script", in the field Value of workflow invoke powershell i put the PS command is right?

i use to connect to vCO client administrator@vpshere.local and i have configured SSO authentication, is correct? or i need to configure LDAP authentication and use the domain admin to launch the powershell script on the host?

thanks :smileygrin:

[igaydajiev]

Could you try invoking following script from vCO itself and from the PowerShelll console and then post the results.

-----------

$env:PSModulePath

get-module -listavailable

--------------------

[Spas_Kaloferov]

In order to use the AD* cmdlets into a powershell session, you must first import the AD powershell module into that session.

[valentinabombel]

i have create a workflow with "invoke powershell script" with your command :

$env:PSModulePath

get-module -listavailable

this is result:

but i don't understand how i can move a specific computer from an active directory folder to another OU.. because i have to pass to the PS command the computer name, but i need to be dinamically with new virtual machine created (every new vm have a different computer name)

thanks for help :smileygrin:

[Spas_Kaloferov]

HI,

Commands seems correct . I've just tested it. Note that i'm on a PSv4 Host. What you can try is importing the module with all parameters: Alias, Cmdlet, Function, and Variable . Something like this:

import-module activedirectory -Alias:@() -Cmdlet:* -Function:* -Variable:*
get-adcomputer computername | Move-ADObject -TargetPath 'OU=Computers,OU=xxxxx,DC=xxxx,DC=xxx'

Ref: https://connect.microsoft.com/PowerShell/feedback/details/716857/module-partially-loads-with-import-...

As for passing parameters to a PS script you can use this WF as starting point.

[valentinabombel]

i have manage my script and now work

i have use for my scope this command:

Import-Module ActiveDirectory

Get-ADComputer -Filter 'Name -like "machinename*"' | Move-ADObject -TargetPath 'OU=Computers,OU=xxxx,DC=xxx,DC=xxx'

in machinename* field you put the machine name start with... so i use as machine prefix in vCAC clone, i put clone* so all vm clone migrato to another OU

[valentinabombel]

if i try to invoke an external ps1 script on a server, and it call an active directory object the orchestrator return me an error, but if i try to call a simple script for exemple only print a word it work..

to better understand:

if i invoke this script "write-host testword"   this work and in ochestrator log i can see the result

but if i invoke a script that it use the Import-Module ActiveDirectory and the Get-ADComputer i have an error:

PowerShellInvocationError: Errors found while executing script

If you go to the powershell host which is being used by vCO and you run the command import-Module ActiveDirectory and the Get-ADComputer , does it work ? From the message i would suggest the powershell host cannot contact the AD server to query the objects.

[valentinabombel]

yes, if i run the command from the powershell in the host it work correctly, only from orchestrator this doesn't work... it's possible a problem of authorization? who is the user run powershell in the host ?

[Spas_Kaloferov]

Well you need Domain Credentials to query the info from AD. the user ID under which the command is being run when running from vCO is the user ID you have used when you have added the powershell host in vCO. If you have used local admin credentials when adding the powershell host you might not have enough permissions to perform this operation.What you can do is :

- add the -Credential switch to the get-adComputer command and supply domain credentials. Use domain credentials that have enough permissions to query AD (Lesss complex to achieve / Not so recommended as you have to hard code credentials in the script. )

- Add again the powershell host and use Kerberos as authentication. Use domain credentials that have enough permissions to query AD. (more complex but no credential hard codding needed)

You might try the 1st approach just ot be sure this is your problem and might consider implementing the second for more long term / production solutions.

Some guidance as also examples of credential passing in a script can be found here:

Using CredSSP with the vCO PowerShell Plugin 

[valentinabombel]

i have made some test, and i have understand the problem, i'm sure is a credential problem, the powershell is invoked with local administrative privileges,,and this user doesn't have the privilege to call the import-module activedirectory from another host

now how i can elevate with a command -Credential all my PS script?

thanks :smileygrin:

[valentinabombel]

but i need to use some other command in powershell, for exemple citrix powershell command and this doesent have the -Credential field...

so i think the only way is to add powershell with kerberos authentication..i have try but i receive some error..

this is my winrm get winrm/config

What error do you receive.

[Spas_Kaloferov]

Just to clarify. if i'm not mistaken you cannot import a module form HostB into HostA. Regarding the credentials i do not see the problem of using Citrix cmdlets. You use the credential switch when using the Invoke-Command. Afterwards in the ScriptBlock part you can invoke any PS command regardless if it supports the -Credential switch or not. For Example:

... (taken from the blog above)
Invoke-Command -ComputerName <PowerShellHost> -ScriptBlock { <MyCitrixCmdletCommand> } -Authentication CredSSP -credential $cred
...

[valentinabombel]

now i have reinstalle a new virtual machine ad now i can add without problem the Powershell host with kerberos authentication. when i launch my script from the host work correctly, but when i use orchestrator receive some error.. and now i'm sure the user launches the powershell is domain\administrator and no localmachine\administrator

the error:

it's possible a System.ServiceModel.CommunicationException Timeout socket ?

[Spas_Kaloferov]

Few questions:
Q: What is the script?
Q: Is the Powershell Host where you run the command a Domain Controller or only Domain Member server?
Q: Have you went through the steps i've pointed out in the article?

[valentinabombel]

this is the script i need, is to add machine to xendesktop

Import-Module ActiveDirectory

Import-Module Citrix.XenDesktop.Admin

Add-PSSnapin Citrix.*

$id = Get-ADComputer -Filter * -SearchBase "OU=Computers,OU=TNCLOUD,DC=tncloud,DC=it" | %{$_.ObjectGUID}

$vmname = Get-ADComputer -Filter * -SearchBase "OU=Computers,OU=TNCLOUD,DC=tncloud,DC=it" | %{$_.Name}

New-BrokerMachine -AdminAddress 'xendesktop.tncloud.it:80' -CatalogUid 1 -HypervisorConnectionUid 1 -HostedMachineId $id -MachineName $vmname

Add-BrokerMachine -MachineName tncloud\$vmname -DesktopGroup "Group"

$user = Get-ADUser -Filter * -SearchBase "OU=Users,OU=TNCLOUD,DC=tncloud,DC=it" -Properties * | %{$_.Name}

Add-BrokerUser tncloud\$user -Machine tncloud\$vmname

Get-BrokerAccessPolicyRule -DesktopGroupName "Group" | Set-BrokerAccessPolicyRule -AddIncludedUsers $user

if i launch this manually with powershell in the host, it work perfectly

the powershell host is a machine in the same domain of orchestrator

where is the article you have point?

thanks for your help :smileygrin:

[valentinabombel]

now i have try another test script without citrix command

Import-Module ActiveDirectory

$id = Get-ADComputer -Filter * -SearchBase "OU=Computers,OU=TNCLOUD,DC=tncloud,DC=it" | %{$_.ObjectGUID}

$vmname = Get-ADComputer -Filter * -SearchBase "OU=Computers,OU=TNCLOUD,DC=tncloud,DC=it" | %{$_.Name}

$user = Get-ADUser -Filter * -SearchBase "OU=Users,OU=TNCLOUD,DC=tncloud,DC=it" -Properties * | %{$_.Name}

write-host $id

write-host $user

write-host $vmname

this simple script, from host work correctly but from orchestrator failed, the problem is the import-module activedirectory

i receive this error:
