Use Remote Desktop Connection instead of Remote Web Workplace
For SBS 2008 and 2011 users, an easy and more direct way to connect to your office computer is to configure your Remote Desktop Connection on the computer you want to use to connect to your office computer so that it can find your office computer and connect you without having to use Remote Web Workplace.
Here's How:
Open up your RDP connection, click on the Advanced Tab, then click on the Connect from anywhere Settings Button.
Next, click on the Use these RD Gateway server settings and enter the IP address of your SBS server or fully qualified domain to connect to it. Example: remote.yourdomain.com
Click OK, then in the General Tab, enter the computer name of the computer you are trying to access that is inside your office. Example: mycomputer-pc
Next, enter your domain user name and password, save the connection settings and login!
This is much easier than using Internet Explorer in compatibility view settings, replacing dll's as Microsoft patches them with incompatible versions, etc.
