CompTIA® Server+ : Troubleshooting The Problems

6. Troubleshooting

Identify the problem and determine the scope

  • Question users/stakeholders and identify changes to the server / environment : This requires you to ask questions to the person who was using the server at the time problem occurred. These questions include what happened , if it is a frequent problem, if any specific error message was displayed.

  • Collect additional documentation / logs : Event logs should be checked for any error messages.

  • If possible, replicate the problem as appropriate : Try to replicate the problem yourself or with the help of the person who reported the problem.

  • If possible, perform backups before making changes : A backup should be taken before you start making changes to system to ensure if anything goes wrong there will be no data loss and possibilty of restoration.

Establish a theory of probable cause (question the obvious)

  • Once you have found the symptoms of a problem try to replicate the problem yourself or with the help of the person who reported the problem. Then start analysis from which you can develop theory of probable cause. Question the obvious means tell the user to perform the same task from beginning which is causing problem and observe any unusual activity which user didn't notice.

Test the theory to determine cause

  • Once you have established the theory of probable cause next step is to test the theory. To test this theory on the system giving problem if it requires permissions which are not in your scope of responsibility problem should be escalated to the concerned department.

Establish a plan of action to resolve the problem and notify impacted users

  • Implement the solution or escalate as appropriate : If you have successfully tested the theory and found the solution you can implement the solution. To implement the solution changes should be made one step at a time and once the problem is solved changes should be confirmed otherwise changes should be reversed.

Networking tools

Tool Description
Ping Ping: This command can be used to verify whether the target ip address or host name is present. You need to specify the target IP address or host name. You can ping the loop back address at 127.0.0.1. A response ensures that the TCP/IP stack is installed properly on your computer.
Tracert Determines the route packets take to reach the specified destination.
Ipconfig Displays TCP/IP configuration values, including IP address, subnet mask, and default gateway
Nslookup nslookup provides the IP address of the remote computer after querying the DNS server for the IP config information.
Net used net use can control drive mapping: mounting ("mapping" in Microsoft terminology) drive shares in a network environment. This command makes use of the SMB (server message block) and the NetBios protocol on port 139 or 445.
Route Displays and manipulates route information.
NBTSTAT This utility displays current NetBIOS over TCP/IP connections, and display
NetBIOS name cache.
NETSTAT Displays protocol statistics and current TCP/IP connections since the server was last booted.
