How to close Windows 7 listening ports (TCP 49xxx)?

[Engineering]

System 792 TCP 135 epmap 0.0.0.0 0.0.0.0 Listening N/A RpcEptMapper, RpcSs

System 512 TCP 49155 0.0.0.0 0.0.0.0 Listening N/A

System 792 TCP 135 epmap :: :: Listening N/A RpcEptMapper, RpcSs

System 512 TCP 49155 :: :: Listening N/A

Services.exe seems to be producing the open ports: 49135, 49155, etc.

What's the deal with this?
