In some situations, signaling or traffic issues can cause the network interface to stop working temporarily. Restart the network adapter (Wi-Fi or wired Ethernet, depending…): this basically turns off the network interface and then turns it back on. See this sequence in Figure 8.įigure 8: Various Ping commands check the IP stack, the network interface, the default gateway, and Internet access, respectively. Ping a known working Internet address for whatever reason MS often uses ping as its check). Ping the nearest router or gateway (Use ipconfig to look up the IP address for the “Default Gateway” – on my network it’s at 192.168.1.1, so that means ping 192.168.1.1 is the command to use)Ĥ. Ping localhost (this checks that the current network interface device is up and running)ģ. Ping loopback (this checks that TCP/IP is working, and looks for a response from a synthetic address that’s always available).Ģ. In the background, the troubleshooter checks local network access, Internet gateway access and then actual Internet access through a series of “reachability checks.” You can do the same thing at the command line using the PING command as follows:ġ. But because websites go down, too, changing to a different one helps determine if the “other end” of the attempted connection is itself having problems. Try a different website: Any given website is, of course, somewhere on the Internet. Let’s walk through those items to discuss what the troubleshooters look for, what they might find, and related fixes. The various actions suggested in the troubleshooters cover a wide array of possible problem sources. In our case 192.168.1.253 DEV-WriteBackSC.Figure 7: The wireless version of the troubleshooter checks Wi-Fi connections and capabilities. You have to do the following: Open your windows\system32\drivers\etc\ folder, open the hosts file with Notepad and add an entry for your static IP. Finally, modify your hosts file to associate your static IP address with your computer name. Image 10: Network connection Advanced settingsĥ. Make sure your loopback adapter network connection is at the top of the Connections list (use the up/down arrows if not). From Network Connections, click Advanced, and select Advanced Settings from the menu. Image 9: Loopback adapter Connection DNS configurationĤ. The subnet mask and the default gateway need to be introduced as well. There you type in the static IP that the ClearPeaks network administrator has assigned you (in our case 192.169.1.63). Here, you select Internet Protocol (TCP/IP) and click on the Properties button. Now, let’s right click on the original network connection and select properties. Image 8: Loopback adapter Connection IP address configurationģ. Then click OK and close the properties window. From the properties screen for TCP/IP, select ‘ Use the following IP address’ and fill in a loopback IP address (make sure to pick something not within your current subnet!). Image 7: Network connections List / Loopback adapter Connection TCP / IP settingsĢ. Open the Network Connections list, right click on the new network connection (it’s suggested to rename it to Loopback Adapter Connection before) and select properties. To properly configure the loopback adapter you need to go through the following steps:ġ. This will add the Microsoft Loopback Adapter as a new Local Area Connection in your Network Connections list. You’ll need to click next a few more times, then finish. Select ‘ Microsoft’ as the manufacturer, and ‘ Microsoft Loopback Adapter’ as the Network Adapter.ħ. Select ‘ Network Adapters’ from device types.Ħ. Select ‘ Install the hardware that I manually select from a list’, and click next.ĥ. Select Next to skip over the first two screens, then select ‘ Yes, I have already added hardware’ and select next again.ģ. Scroll to the bottom of the list on the following screen, and select the ‘ Add a new hardware device’ option, click next again.Ĥ. In order to install the loopback adapter in the Windows 2003 Virtual Machine, you need to:ġ. Go through the ‘ Add Hardware’ wizard (from the control panel).Ģ. In fact, Business Intelligence installation will fail for the mentioned environments if the loopback adapter is not properly configured. Having the loopback adapter set up is required before installing OBIEE 11g. The aim of this document is to provide a guide that thoroughly explains the steps of creating and configuring a Loopback Adapter.
