I also would recommend blocking these outbound, if they are not. Especially 137, it's so useful in finding Windows machines on other networks.

Absolutely. All of the NetBIOS ports: 135, 137, 138, 139, 445.Ports 137, 138, 139, 445 have been blocked for a long time. But port 135 wasn't until today... Thanks! Adi
