Install the App-V Databases and Convert the Associated Security Identifiers by Using PowerShell

Use the following PowerShell procedure to convert any number of Active Directory Domain Services (AD DS) user or machine accounts into formatted Security Identifiers (SIDs) both in the standard format and in the hexadecimal format used by Microsoft SQL Server when running SQL scripts.

Before attempting this procedure, you should read and understand the information and examples displayed in the following list:

• .INPUTS – The account or accounts used to convert to SID format. This can be a single account name or an array of account names.

• .OUTPUTS - A list of account names with the corresponding SID in standard and hexadecimal formats.

• Examples -

  .\ConvertToSID.ps1 DOMAIN\user_account1 DOMAIN\machine_account1$ DOMAIN\user_account2 | Format-List.

  $accountsArray = @("DOMAIN\user_account1", "DOMAIN\machine_account1$", "DOMAIN_user_account2")

  .\ConvertToSID.ps1 $accountsArray | Write-Output -FilePath .\SIDs.txt -Width 200

To convert any number of Active Directory Domain Services (AD DS) user or machine accounts into formatted Security Identifiers (SIDs)

1. Copy the following script into a text editor and save it as a PowerShell script file, for example ConvertToSIDs.ps1.

2. To open a PowerShell console click Start and type PowerShell. Right-click Windows PowerShell and select Run as Administrator.

   .SYNOPSIS
   This PowerShell script will take an array of account names and try to convert each of them to the corresponding SID in standard and hexadecimal formats.
   
   .DESCRIPTION
   This is a PowerShell script that converts any number of Active Directory (AD) user or machine accounts into formatted Security Identifiers (SIDs) both in the standard format and in the hexadecimal format used by SQL server when running SQL scripts.
   
   .INPUTS
   The account(s) to convert to SID format. This can be a single account name or an array of account names. Please see examples below.
   
   .OUTPUTS
   A list of account names with the corresponding SID in standard and hexadecimal formats
   
   .EXAMPLE
   .\ConvertToSID.ps1 DOMAIN\user_account1 DOMAIN\machine_account1$ DOMAIN\user_account2 | Format-List
   
   .EXAMPLE
   $accountsArray = @("DOMAIN\user_account1", "DOMAIN\machine_account1$", "DOMAIN_user_account2")
   
   .\ConvertToSID.ps1 $accountsArray | Write-Output -FilePath .\SIDs.txt -Width 200

           Write-Output $SIDs
       }
   }
   

3. Run the script you saved in step one of this procedure passing the accounts to convert as arguments.

   For example,

   .\ConvertToSID.ps1 DOMAIN\user_account1 DOMAIN\machine_account1$ DOMAIN\user_account2 | Format-List” or “$accountsArray = @("DOMAIN\user_account1", "DOMAIN\machine_account1$", "DOMAIN_user_account2")

   .\ConvertToSID.ps1 $accountsArray | Write-Output -FilePath .\SIDs.txt -Width 200”
