 The Network Utility provides these useful network tests:
-. **Ping:** The ping diagnostics utility is the primary TCP/IP tool used to troubleshoot connectivity, reachability, and name resolution. Ping verifies IP-level connectivity to another TCP/IP computer by sending Internet Control Message Protocol (ICMP) Echo Request messages. Receipts of corresponding Echo Reply messages are displayed, along with round-trip times.

->**Note:** The Windows firewall default settings block the ICMP echo requests used for ping command. To enable ICMP echo on Windows, go to Control Panel -> Windows Firewall -> Advanced settings -> Inbound Rules and enable File and Printer Sharing (Echo Request - ICMPv4-In) in the active security profile.
+''ping zoo.mcneel.com''
+Successful ping response looks like:
+<code>
+> ping zoo.mcneel.com

+Failed ping response looks like:

+Press **Ctrl+C** to cancel the **ping** command.
+. **nslookup:** The DNS Lookup diagnostic utility displays information that you can use to diagnose Domain Name System (DNS) infrastructure.
+''nslookup zoo.mcneel.com''
+Successful ''nslookup'' response looks like:
+<code>
+> nslookup zoo.mcneel.com

-{{:zoo:nu_lookup.png?640|Lookup}}
 .  **Traceroute:** The Trace Route diagnostic utility determines the route taken to a destination by sending Internet Control Message Protocol (ICMP) echo packets with varying IP Time-To-Live (TTL) values to the destination. Each router along the path is required to decrement the TTL on a packet by at least 1 before forwarding it, so the TTL is effectively a hop count. When the TTL on a packet reaches 0, the router should send an ICMP Time Exceeded message back to the source computer.

-. **Port Scan:** The Port Scan test scans for open TCP ports. In the case of the Zoo, you will want to scane for for TCP Port 80.

+. **Port Scan (nc):** The Port Scan test scans for open TCP ports. In the case of the Zoo, you will want to scan for TCP Port 80.
+''nc -z -v zoo.mcneel.com 80''
+Successful ''netcat'' response:

 //If this test fails, then make sure the Zoo server service is running. You can do this by using either ZooAdmin.exe or the Services applet in Control Panel. Also, make sure __[[zoo:window7firewall|TCP Port 80 is open on any firewall software]],__ for both incoming and outgoing traffic, running on the Zoo system.//
