Powershell and Active Directory

Hi Expert,

I am Sachin, new to powershell and Active directory. I am creating a web based application(asp.net, C#) which should create a new user/group in Active Directory. I want to run that application on my laptop which is not part of any domain. But, the server machine whose active directory i want to call is a domain server. Can i update Active directory content from any machine (Public) if I have required credentials ?

Please share some code snippet. It's urgent!!!
