Anyone have any idea how to get Routerstats to work on Windows SBS.
It doesn't seem to have any proxy config so connection fails.
IE has proxy configured and can browse the router's webpages but Routerstats doesn't seem to be picking that up.

UPDATE: It runs ok on a client PC (mine) but I would have preferred to have left it running on the Server. Oh well

I have my own MRTG scripts monitoring my network, so I only ever set up Routerstats for a trial, once, a while ago.

Have you tried disabling the proxy configuration in IE?
Can you ping and telnet (try port 23) to the router

Depending on your SBS networking setup, it could be the proxy is interfering with connectivity.

A bit more detail would be useful. 
How many network cards in the server?
Are you using ISA server?
What is the make and model of the router.
