Checking Current ConfigurationPrint the current unit Internet Parameters configuration.Locate a PC connected to the same Subnet Mask as the unit, then from the DOS Prompt, type thefollowing command-line utility: "ipconfig /all" for Windows 98/Me/2000/NT/XP.Verify that the displayed Network configuration on the PC, matches the following Internet Parametersettings of the unit:Default Gateway IP Address:DNS Server IP Address:Subnet Mask: (whether it is valid)For Windows 98 / Me / 2000 / NT / XPThe following example shows the output after you type "ipconfig /all" at a command prompt:From the above examples, you know the Network configuration for the specified Subnet Mask is asfollows: IP Address: 192.168.3.4; Subnet Mask: 255.255.255.0; Default Gateway (Default Router IPAddress): 192.168.3.254; DNS Server: 192.168.1.1 and the Domain Name: labo.pcc.com(obtained from the Host Name).3. Using "PING" to Test Physical ConnectivityThe Packet Internet Groper (PING) is a command-line tool included with every Microsoft TCP/IP client(any DOS or Windows client with the TCP/IP protocol installed). PING is a simple utility that is used tosend a test packet to a specified IP Address or Hostname, then, if everything is working properly, thepacket is echoed back (returned).Sample command-line PINGing and parameters are shown below. There are several available optionsthat can be specified with the PING command. However, for our examples, we will use two options (-nand -w) which are commonly used when the response from the destination location is too long.-n count : The number of echo requests that the command should send. The default is four.-w timeout : Specifies the period PING will wait for the reply before deciding that the host is notresponding.Host Name : ec4.labo.pcc.comDNS Servers : 192.168.1.1Node Type : HybridNetBIOS Scope ID :IP Routing Enabled. : NoWINS Proxy Enabled : NoNetBIOS Resolution Uses DNS : NoEthernet adapter IBMFE1 :Description : IBM 100/10 EtherJet PCI AdapterPhysical Address : 00-04-AC-EE-9C-E8DHCP Enabled : NoIP Address : 192.168.3.4Subnet Mask : 255.255.255.0Default Gateway : 192.168.3.254Primary WINS Server : 192.168.3.18C:\>ipconfig /allWindows NT IP Configuration
