adding an addtional subnet to a 2003 AD domain.

I have two physical sites with the following IP Schemes setup.

SiteA: 10.1.1.0/24
SiteB: 10.1.2.0/24

I need to create an additional subnet(10.1.4.0/24) at SiteA

 I have setup the routes and i am able to ping 10.1.4.0 from both subnets, but do i need to do anything in AD?

Within AD Sites & Services you should create the subnet and then link the subnet to the proper site. This way AD knows which subnets belong to which sites.

If you wanted all of them in the same site you could use a catch all subnet   http://technet.microsoft.com/en-us/magazine/2009.06.subnets.aspx   Not needed in your case though.

Thanks
