We are having a problem getting the HTTP monitor to work when targeted on a node running Server 2003. The exact same monitor works fine when applied to a Server 2008 node.
Anyone have any idea what may be going on?
What is the error that is returned? Does it work when you open the browser on the Orion server and enter http://<ip address>:80
Be sure to enter in the IP address and not the host name or FQDN as that may work differently then the IP address. By default the HTTP Monitor in APM uses the IP address to access the host via HTTP. Your server may be using host headers, or the root page not be available. I.E. http://10.2.3.4:80 might not work, but http://10.2.3.4:80/mypath might work fine.
