Question : Exchange 2010 new-mailbox fails

I'm trying to learn Exchange 2010 and setup a lab environment with some VMs.  After installing Exchange 2010 I can create mailboxes for existing users without a problem.  I can create mail contacts and distribution groups without a problem.  But I cannot create a mailbox for a new user regardless of the type.  From my understanding doing this is suposed to create the AD user object for me.  I get a weird powershell error type error when going through the GUI.  So I jumped to the exchange shell and tried the new-mailbox command with basic arguments.  

I get the message below.  Any ideas what could be going wrong?

Exception calling "GetSteppablePipeline" with "1" argument(s):  The type initializer for 'Microsoft.Exchange.Management.RecipientTasks.NewUserBase' threw an exception"
CategoryInfo:        NotSpecified: (:) [] MethodInvocationException

Answer : Exchange 2010 new-mailbox fails

ADWS was not running on the domain controler.  This was preventing Exchange from creating the AD user account.
