First, if you are able to connect to the internet, you should be able to use VPN to access on-campus servers. Click the following link for information on connecting to VPN in windows. However, sometimes the network you are on may be too slow, or there is no internet available where you are. If this is the case, you can use Offline File Synchronization to access your files.
When using offline file synchronization, the files that you select are automatically downloaded from shared folders on the network and stored on your computer. When you disconnect, the files are available to use. When you reconnect to the network, your changes are added to the files on the network in a process called synchronization. If someone else on the network made changes to the same file, you can save your version, keep the other version, or save both.
Unfortunately, Mac OS X does not support offline file synchronization.
Setup in Windows Vista/7
- Locate the network file or folder that you want to make available offline.
- Right-click the file or folder, and then click Always Available Offline.
The next time you try to access this file or folder, you will be able to open it even if the network version is unavailable. This answer was originally published by Microsoft (http://windowshelp.microsoft.com/Windows/en-US/Help/02ecf57a-fa36-40be-a5c2-907f51cda1fe1033.mspx).
