HP Insight Manager uses ICMP to check if a box is up or not with Windows 2008 ICMP is by default blocked on the firewall, we need to open this up for Insight Manager to work , to do this, you’ll need to create a rule that allows the Insight Manager Server to ping the server being monitored using the Windows Firewall with Advanced Security MMC.
On the server, open the Windows Firewall with Advanced Security from the Administrative Tools menu.
In the left pane of the Windows Firewall with Advanced Security console, right click the Inbound Rules node in the left pane and click New Rule.
On the Rule Type page, select the Custom option and click Next.
On the Program page, select the All Programs option and click Next.
On the Protocol and Ports page, click the down arrow in the Protocol Type drop down list, and select the ICMPv4 option and then click Next
In the Scope dialog box, accept the default settings for the local and remote IP addresses, which is Any IP address. Click Next. (or in the remote address you can just specify your Insight Manager server)
On the Action page, select the Allow the connection option and click Next.
On the Profile page, remove the checkmarks from the Private and Public checkboxes and click Next.
On the Name page, give the rule a name. In this example we’ll name the rule Allow ICMP Request. Click Finish.
You can see the Allow ICMP Request rule in the list of inbound rules.
