Users who want to connect to WestlawNext Campus Research from home should not have any more problems (the search box had been missing if you were using any browser except for IE).
After I called technical support at Thomson, they sent me some additional lines to add to the database stanza in the configuration file in EZproxy. After I restarted the EZproxy server and tested the connection from my office and my home, it was apparent that the EZproxy settings were the source the problem (actually, it’s the vendor that started this by making changes to the interface and system without notifying customers like us so we could then tinker with our EZproxy servers as needed).
