What troubleshooting step should be taken first if a user cannot access their network share?

When a user cannot access their network share, the first troubleshooting step should be to check network connectivity to the server. This is crucial because if there is no network connectivity, all subsequent troubleshooting steps regarding permissions, server status, or even restarting the user's computer would be futile.

By ensuring that the user's device is capable of reaching the server, you can eliminate the possibility that the issue is simply a matter of a disconnected cable, a problem with the wireless connection, or an issue with the network configuration. Confirming that there is proper connectivity first allows you to isolate the issue to either a connectivity problem or something deeper like permissions or server operational status.

If network connectivity is intact, then you can proceed to verify permissions, server status, or potentially restart the user's computer, but starting with connectivity is foundational in troubleshooting this type of issue.
