SharePoint Trouble Shooting for Administrator (On-Promises)
There are numerous way to trouble shoot when SharePoint Farm is down or any services are not running properly:
1. Check Servers are running by pinging from any machine. Example: ping
2. Check DB is up and running by creating udl file and passing the SharePoint DB instance and credential and test the connection.
3. Check your IIS, app pool
4. Manually check SharePoint services
5. Check is there any 3rd party tools or new updates applied on system level such as firewalls etc.
6. Check security policy or AD group policy applied?
7. Read the application ULS Logs using ULSViewer application
8. Read Windows application event logs filter with Error and Critical/High from front-end/application/DB servers
9. Check disk storage in all SharePoint servers
10. Note CPU and Memory utilization
11. Make sure farm account is active (not locked out, not disabled etc.)
12. Check other application running on your intranet? If No, meaning could be network issue or datacenter
13. If Portal application is running on https secure socket layer, double check the SSL certificate expiry date
14. Restart all Front-end servers’ IIS with no force option one by one
15. Read the browser HTTP/Request based error 404 or 401, 500, 503
16. Investigate is the issue related to one user/group of users/building Zone/Region?
17. Clear client browser cache or refresh browser using Ctrl+F5
18. Add URL/APP to trusted sites
19. In the last you need to open the support ticket with Microsoft.
20. Check BlobCache Size in the web.config file with storage drive
I decided the list down soem useful checklist which I experienced so far becasue when the evnironment is down sometime it is difficult to focus on key areas.
In the end it is always good to share your experience with others.
