It’s usually a good idea to have some kind of checklist that you can tick off to show that you’ve completed these tests so that if a problem emerges, you can show with your logging that problems started after a specific date or time. Here are a number of the checks I run on systems. I have broken them into monthly, weekly and daily. Monthly checks Clean server room and coms room. Remove dust build up from server casing. Check air conditioning fans and vents. Check room security. Check Active Directory for old or unused computer or user accounts. Ensure all updates are downloading to Windows Server Update Services. Clean up Windows Server Update Services. Apply Updates from the previous month to Servers. Note, if there are hundreds of servers this would be a weekly task. Run a test restore from a random backup job. If there are clustered systems for redundancy, check a random service to ensure it fails over correctly. Weekly checks Check temperature of server rooms. Do a visual inspection of all servers. Distribute updates to workstations. Check server logs for errors. Check priority workstations for errors. Check that all anti-virus and other software is up to date. Check Anti-Virus logs for outbreaks or irremovable infections. Check logs from CCTV and door access systems to ensure there are no issues.
