Troubleshooting Problems with Off-Campus Database Access

If you get a call from a patron saying that they're not able to access our databases from off-campus, unless EZproxy went down at that very second, it's highly likely that the problem resides with the patron's computer or network, not with us.

Of course, if you get these calls, please feel free to just refer folks to me, by phone or email. But, if it's after my office hours and they don't want to wait to talk to me, first get their contact info so I can get back in touch with them if I need to.

Then, ask them where they're trying to connect from. 9 times out of 10, it's going to be their workplace, so it's probably a firewall thing. Most of the calls I've gotten were from students who couldn't connect from major corporations like Morgan Stanley and Comcast. After consulting with our EZproxy administrator, I learned that, for security reasons, many companies are restricting Internet traffic on anything other than port 80, but EZproxy uses another port, so our databases are blocked. We just have to tell folks that, until something changes, they won't be able to access the database from their workplace.

If they're trying to connect from home, and they're not running some major firewall, the next most likely scenario is that their browser isn't set to accept cookies. Gotta accept cookies for EZproxy to work correctly. Have them set that up and see if it works.

If it's neither of those two things, have them clear the cache and try again. It's highly unlikely that it would go further than that, but, if it still doesn't work it may be a genuine problem with the DB and I'll need to speak to the vendor.

Again, you don't have to do any of this. If it's during my office hours, or they don't mind waiting until I am back in the office, just send them my way, but I thought you all might like a little more background info too.
