Server & Computer Network

Maintenance Checklist

Over the many years, APACMS have established a very large and thorough Server and Computer Networking maintenance checklist. The types of things we go over within this checklist help our clients get the most out of their computer equipment.
By discovering and resolving issues on the spot and performing routine tasks on our client's IT equipment, we are able to help ensure our clients remain free from data corruption, security breaches, and poor network performance, just to name a few.

Just like a car or any type of automobile, you need to maintain it so that it will continue to work throughout the ages. This type of analogy is a good way to understand the requirements of your office's IT infrastructure. We usually perform this maintenance monthly however; some clients have very large networks and require maintenance on a fortnightly basis. The types of checks we perform include.
