You can try team viewer, the free version works and no need to purchase

Install on both machines and must have internet access
-have teamviewer running at office and copy the login and password at office PC teamviewer screen and bring home
-open teamviewer on home PC and then enter the login information and you will be connected to your work PC

Work PC must be running, would turn off any screensavers or power options at work, leave PC running connected to the net

TeamViewer Download

Only your company's IT department can allow you or configure your external access to the company's Domain.
