IT administrator guides

Start with the system closest to the problem.

Guides available

Accounts & Google Workspace diagnosis

Diagnose account, browser, permissions, performance and device issues before deciding whether a Workspace problem is local or school-wide.

Windows & Office troubleshooting

Work through Windows Update failures, repair components and services, then handle common Microsoft Office update and installation problems.

Networks & shared devices

Use these guides when a problem appears to be linked to the school network, web filtering, shared computers or shared classroom panels.

Interactive displays & device management

Configure ViewSonic panels, manage EDLA permissions and firmware, and prepare classroom displays for reliable school use.

AI & IT knowledge workflows

Use AI to organise technical knowledge, turn troubleshooting notes into reusable guidance and create repeatable support workflows.

Escalation & evidence

Collect enough information to make the next support conversation useful instead of starting the investigation again from the beginning.

Before deeper troubleshooting

Establish the scope first.

Good troubleshooting starts by identifying whether the failure belongs to the user, device, application, network or wider school environment.

1

Confirm whether the issue affects one user, one device, one classroom or multiple users across the school.

2

Record the exact error message, error code, device model, operating system and application version where relevant.

3

Check whether account policies, proxy settings, firewall rules, web filtering or device-management settings could be controlling the behaviour.

4

Before making a wider change, test the proposed fix on a limited number of devices and keep a record of what was changed.

Need a second pair of technical eyes?

Send us the affected system, device or application, the scope of the issue, exact error details and the troubleshooting already completed.
