Basic network troubleshooting steps
Check for local connectivity issues: The first step in troubleshooting network errors is to check cables, devices, switches, and routers for proper functioning. Teams can also try restarting devices such as the modem, PC, and router to resolve simple network issues. Another issue could be LAN connectivity. To identify and troubleshoot LAN connectivity issues, try to ping the destination IP and check configuration settings and source host.
Rectify the duplicate entry of IP address: To check whether the computer is receiving a valid IP address or not, type "ipconfig" in the command prompt. If the IP address starts with 169, it’s receiving an invalid IP.
Perform a DNS check: To determine server issues, use command “nslookup.” Results such as refused, timed out or server failure indicate the problem originates from the DNS server of the destination URL.
Check malware protection: Check your malware protection tools to ensure they haven't flagged any application, program, or settings affecting network performance.
Review logs: Reviewing logs is also one of the best ways to identify and troubleshoot network performance outages and issues. Logs provide elaborated information on each device, application, and program to help track the root cause of the issues.
