Service process crash

A service process has crashed and a specific service cannot be accessed. The problem might be related to the application underpinning the service.

DNS failure

DNS is a system that translates domain names into IP addresses, allowing computers to find each other on the internet. If DNS is not working, you might be able to connect to servers by IP address but not by name.

Troubleshooting DNS

Troubleshooting DNS involves checking if the domain name can be resolved to an IP address. The nslookup command is a tool that can be used to perform this check.
