Active Directory Services - Email Creation

On the Active Directory Services Server or the remote computer that holds the Active Directory Services, we need to create and  install WINDOWS service 

This windows service holds a class that contains the following methods: 

CreateUserEmail ( string adsUser) 

String adsUser must be in the form [first name] [space] [last name] [space] [company name(OU, or organizational unit in ADS)] 

SecureYourString( string input ) – this method converts a regular string to secure string  

On the ASP.NET website, that is hosted on remote computer, away from Active Directory Services, running on local or production IIS, we have a class, name it whatever you want, that contains a method: 

ADS_CreateMailBox ( string firstName, string lastName, string userName, string companyOU) 

Inside this method we use the following two classes: 

System.Runtime.Remoting.RemotingConfiguration.RegisterWellKnownClientType() 

RemotingConfiguration.IsWellKnownClientType() 

And here is the trick that makes it all happen:  On Active Directory Services Server, and on the Windows Service that we created earlier over there, a reference DLL, and not Windows or Web Service reference, should be added or copied from our local ASP.NET website.
