Troubleshooting Server Down Issues

Troubleshooting server down issues is never an easy task. Whether you have a small home network, or a super connection of thousands of computers, there are meticulous steps you need to take to get your server back up running. Here is a comprehensive outline of the steps that you need to take when troubleshooting.

Troubleshooting Server Down Issues

1. Analyze Your Network Infrastructure

You will have a better chance at troubleshooting network problems if you first figure out where everything is connected in the infrastructure. You will be able to spot network vulnerabilities by finding out all applications, processes, and computers on the network.

2. Study Your Network

If you don’t have an infrastructure design to go by, you will have to learn your network’s layout when analyzing your connectivity. Several tools can help you to map out the entire network infrastructure. Tools such as IPCONFIG can aid in finding the problem. Run the network diagnostic application to understand the nuts and bolts of your system.

3. Connection is Down

From the network troubleshooting application, find out from the OSI model if all the seven layers are working correctly. Usually, if the first layer doesn’t work the whole connection will be down. Check whether the network cable is plugged in. The issue could also be a broken connection where the network cable is disconnected or cut. Also, check whether the network switch is working correctly.

4. No IP Address

Your server could be down just because of unknown IP address settings. Anon IP address such as 0.0.0.0 or an automatic one that starts with 169.254 will typically result in server down problems. You will need to obtain a valid IP address before you can get your server back up. To solve this problem, open the network and sharing center and select obtain IP address automatically.’ You can also enable a DHCP server to resolve the issue.

5. No DNS Servers

Without DNS servers configured on your network, all communication will only be possible through an IP address. A server down issue, in this case, might be a broken a line between the router and the internet. To resolve this issue set DNS server to manual configuration and fill in the server IPs. You can also configure Google public DNS servers to help you ping and trace hung packets.

6. No Default Gateway

Your servers could be down because there is no default gateway IP address. This breaks the communication between the subnet and the local area network. You will still be able to work as usual on your local servers. If you need to get to an external network, however, you will need to configure a gateway IP address manually.

7. Misconfigured IP Subnet Mask

A misconfigured subnet mask IP can impede server communication. You can manually configure this IP subnet mask or work with the DHCP server to identify the source if there is a misconfiguration.

Summary

When troubleshooting server down issues, you should understand the various aspects of your connection. You can quickly learn all the details using a server troubleshooting application. To get your servers back up and running, configure IP address manually or automatically, configure Google Public DNS servers to help you ping and trace hung packets and manually configure an IP subnet mask. If your server is having issues and you cannot seem to pinpoint the problem, Gordian Networks provides a team of experts to help eliminate any issues.
