You can use remote access programs like on premise R-HUB remote support servers. It allows remote access of all computers and mobile devices from anywhere anytime.
I was a huge fan of Teamviewer until I started experiencing issues. Hence, switched over to a better alternative: R-HUB remote support servers. It works without any hassles and plus works from behind my company’s firewall, hence better security. Plus provides a simple and easy to use interface.
