Adding exception to firewall in Windows Server 2003/2008 using C#

I want to add exceptions to windows firewall in Windows Server 2003/2008.

I have written the code which works fine for Windows 7, but it doesn't work on Win server 2003/2008.

The problem is with the开发者_开发问答 NetFwTypeLib (FirewallAPI.dll)

Can someone guide on the same.

It seems like its not possible.

Also from the link given in the comment by Adrian talks about same. Hence am closing the question.
