I'm having an issue with NetPath not showing the identity of one of our internal routers.
it's showing "No Response The device at the node(s) did not respond to repeated access attempts. This may be because it is blocking access."

From the probing machine I can successfully do a trace route and it does show the missing router.
C:\>tracert sc2000.net
