Server Fault is a question and answer site for professional system and network administrators. It's 100% free, no registration required.

I have 2 clients on my LAN that I'm trying to get to "see" each other. The first as follows

Computer1

IP 172.21.62.230
Subnet 255.255.255.224
Default gateway 172.21.62.225
Preferred DNS server 172.21.62.227

Computer2

IP 172.21.62.244
Subnet 255.255.255.224
Default gateway 172.21.62.225
Preferred DNS server 172.21.62.227

On computer1 I have a webserver and application server running. This works fine on http://localhost:8500 and on http://172.21.62.230:8500/ however I cannot ping 172.21.62.230 from computer2 ( I can connect to 172.21.62.230 using Remote Desktop).

I thought I would be able to connect the web server via browser from computer2 at http://172.21.62.244 but I cannot.

How can I work out whats going on?

This is much more of a question for Super User, not Server Fault. –  Jed Daniels Jul 14 '11 at 21:04

Windows firewall blocks ping by default. Either enable ping to pass though or disable the firewall.
