You can use OpenRemoteBaseKey to access the remote registry but before that you need to impersonate an account with the correct access rights using WindowsIdentity.Impersonate.

The following MSDN link contains a complete sample to login as a different user programmatically: http://msdn.microsoft.com/en-us/library/system.security.principal.windowsimpersonationcontext.aspx
