This question already has an answer here:
We are a medium sized company which has VPNs to more than 20 locations. We sometimes get complaints regarding access to the terminal server, and I would like to diagnose this as either a server issue or Internet connection issue.
What I am looking for is a utility that I can give an IP address to, and have it monitor/record whether or not that address is live. I am aware of munin, but I am looking for a more dedicated tool for this task, something that does not take a lot of time to get up and running.
EDIT: Using W2k3 terminal server. But I want to just monitor the VPN link between corp offices and the facility in question. Just something that pings on a determined schedule and records the result.
