Try contacting the C&IT Help Desk for assistance, or try reloading the resource after logging into VPN. You may be encountering one of the following issues:
Trying to access EZproxy on port 2048, and behind a firewall that blocks access to port 2048 (in this case, simply delete ":2048" from the URL and try again).
Using a plugin or spyware protection that misidentifies EZproxy as malware.
Using high-speed dial-up or a web accelerator (try turning off the highspeed or accelerator feature while using EZproxy).
