SMS and Multiple Subnets connected over WAN

[Guest_imported]

I am trying to set-up SMS 2.0 to a site which is based on small multiple WAN sites, one router and 3 PC’s per site this Network consists of 150 small sites. I have installed one PDC and also installed SMS 2.0 on it as a test server; I have enabled Network Discovery method and defined all the subnet ranges in sites boundaries and also in network discovery option. My SMS server is connected to WAN through a CISCO router through this router I can ping every remote router and also remote machines. But when I run discovery SMS only finds machines on the local subnet (where SMS is directly connected). And it also finds all the remote routers but it does not find any remote machines connected to remote routers, Although I can ping every machine. WINS is not installed on this network.

Please help
