title: DHCP server management API in dot net application
body: <p>I need to use DHCP server management API in my C#.net application. My target platform is  Windows Server 2008 R2 (64 bit obvious I guess). I am getting this error 
  "A reference to 'dhcpsapi.dll' could not be added. Please make sure that the file is accessible, and that it is a valid assembly or COM component."</p>
  
  <p>Assuming it is a COM dll I even tried TLB export but with error 
  TlbExp : error TX0000 : Could not load file or assembly 'dhcpsapi.dll' or one of its dependencies. The module was expected to contain an assembly manifest.</p>
  
  <p>I found this assembly in C:\Windows\System32 folder. I have also tried starting VS in "Run as Admin" mode. Any help, highly appreciated.</p>
