FIM 2010 R2 SP1: Inbound Sync Rule CustomAttributes Script "DomainObjectSid_IFFSStatement.ps1" script provided by The FIM Scriptbox. "Error: Could not find a forest identified by: 'domain'."

After reviewing the Microsoft guide "Syncing Active Directory with FIM", I got to the stage of populating the Synchronization Rules using the FIM Portal. In the guide the following section outlines how you must generate a CustomExpression string.
 
How to Sync Active Directory with FIM.


As the domain I was trying to sync with Active Directory was Windows Server 2003 based, which does not natively have PowerShell (or the AD DS PowerShell cmdlets) I used a Windows Server 2012 R2 VM with the AD DS server role installed.
At first I had to reconfigure the ExecutionPolicy to allow Unrestricted scripts. I then tried to run the DomainObjectSid_IFFSStatement.ps1 script provided by The FIM Scriptbox. I received the error Error: Could not find a forest identified by: 'domain'.
To recognize where in the code the script was failing I opened the script in the PowerShell ISE and selected small sections of the code and used the Run Selection button to break out where then the code encounters an error.
 
In this instance it was on Line 10 $ForestObject = Get-ADForest that was causing the script to fail. At first I thought it was a DNS issue that was causing the issues so I did all the usual things and could not find anything.
The fix in this case was to configure the Active Directory Web Services service to start Automatically on the system starting. Once I did this and re-run the script it generated the required CustomExpression string I needed to continue.
