BNবাংলা#Troubleshooting
Troubleshooting is the step-by-step process of finding the real cause of a problem instead of guessing at fixes. For websites and e-mail that means reading error messages, headers, logs and DNS records carefully. A good troubleshooting routine starts with the simplest checks and changes one thing at a time.
