Microsoft CRM Dynamics 2011 PowerShell Error when disabling an organization - powershell

Question

Whenever I try the following line in a powershell script :
Disable-CrmOrganization -Name MyOrganization
I get the following error :
Disable-CrmOrganization : The Deployment Service cannot process the request because one or more validation checks failed.
+ Disable-CrmOrganization <<<< -Name MyOrganization
+ CategoryInfo : NotSpecified: (:) [Disable-CrmOrganization], FaultException`1
+ FullyQualifiedErrorId : System.ServiceModel.FaultException`1[[Microsoft.Xrm.Sdk.Deployment.DeploymentServiceFaul
t, Microsoft.Crm.PowerShell, Version=5.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35]],Microsoft.Crm.Pow
erShell.DisableCrmOrganizationCmdlet
However, if I manually disable the organization, I am able to execute the following line with no problem :
Remove-CrmOrganization -Name MyOrganization
Any idea why I cannot disable the organization with powershell?

You might have run across this page: Use PowerShell to Call the Deployment Web Service for the CRM PowerShell references.
Running this command gives additional error details: $error[0].Exception.Detail.ErrorDetails
Additionally the Windows Application Event Log was showing an error (in my case anyway):
Web service request FindItems to Report Server http://myserver/reportserver/ReportService2005.asmx failed with SoapException. Error: The permissions granted to user 'NT AUTHORITY\NETWORK SERVICE' are insufficient for performing this operation.
Which lead me to this post:

The solution was to run the CrmDeploymentServiceAppPool under an account with elevated priviledges. Logon as a service and sysadmin in SQL Server according to the post.

when I execute 2 times it works so try with:
try {
Disable-CrmOrganization -Name "oragnization_name"
}catch {
Disable-CrmOrganization -Name "oragnization_name"
}
