Alternate option to get same changes in Exchange server 2003 instead of running scripts in powershell

Hi MS Support team,

We are have exchange server 2003 SP2 on windows server 2003 Standard Edition SP2 and Powershell 2.0 installed.

We have to install SAP Groupware connector 5.0 to connect CRM system with the above exchange server 2003. In this scenario SAP installation document have provided  some Powershell scripts to change properties of admin account and to create a new throttling policy, Please find the given script will give more idea on this.

1. Add-ADPermission -Identity “Exchange Administrative Group (FYDIBOHF23SPDLT)”  -User <Groupware Administrative Account Name> -AccessRights ExtendedRight -ExtendedRights "View information store status" -InhertanceType Descendents

2.New-ThrottlingPolicy -Name <Name of the throttling policy> -RCAMaxConcurrency $null -RCAPercentTimeInAD $null -RCAPercentTimeInCAS $null -RCAPercentTimeInMailboxRPC $null;

3. $b = Get-ThrottlingPolicy <Name of the throttling policy created in previous step>;Set-Mailbox -Identity <AdminUserAccount> -ThrottlingPolicy $b;

This script for grant permission for GW connector Admin user a/c, but it is not working in our exchange server 2003, and getting the error like this."'Add-ADPermission' is not recognized as the name of a cmdlet...........Error"

Here we are using Windows 2003 server standard edition SP2 and added the Powershell by an Update for Windows Server 2003- WindowsServer2003-KB968930-x86-ENG.exe

Can you please provide any alternative manual steps to get the same results on exchange server 2003, instead of running the scripts. Or any alternate method that provide the script availability in the  exchange 2003 Powershell for administration.

Please consider this an urgent, awaiting your favorable response.

Thanks+Regards
