I have remote locations connected by fiber.
I have to get up on them Lan to Lan VPN since it is a requirement of the company and to meet standards.

The tunnel is working properly but I can not make the machine see my Active Directory, mounted on windows 2003 server.

I can not give users access to my domain, and that does not resolve the name

I can not implement policies for the active directory.

Any idea how to pass this traffic through the VPN.

broadcast or multicast are not supported over IPSEC tunnels.

try to use GRE in site to site VPN it supports Broadcast and Multicast even routing protocols.
