Browsing issues…

I have a NT 4.0 network divided into 2 subnets connected via 2 routers. On one subnet I have a WINS server and the PDC, and on the other subnet I have another WINS server and a BDC. Everyone can log in fine and ping everyone on both subnets but network neighborhood doesn’t appear to be working. Specifically the subnets don’t see eachother….yet you can ping them via their name. Interesting?
