I've checked my browser settings. What else could be the problem?

Have you tried a different browser?
Some Add-ons and Plug-ins  designed for specific browsers may be incompatible with certain webpages.  

Do you have a personal firewall/virus protection installed on your PC?
Many corporate or government systems use a firewall for security purposes. If you are trying to log in from home your personal firewall can also cause problems. Norton Personal Firewall is a common offender. Temporarily disable your firewall/virus protection and see if that allows you to connect properly. You will need to consult your software manual and/or contact the software company's technical support for help in setting your security software so that you can access our library resources. 
Is the SSL facility disabled on your browser?
This can prevent you from logging onto LexisNexis. For further information, see the LexisNexis page.  

I'm able to search for items in an electronic index but I'm having problems viewing or printing Adobe Acrobat files

Adobe Acrobat documents are also known as PDF (Portable Document Format) files. PDF documents are now widely used to publish full-text articles on the Web. You need a copy of the Adobe Acrobat Reader plug-in to view and print a PDF document. In most cases, this presents no problem, as a copy of this plug-in was almost certainly installed with your browser. If you don't have a copy of Adobe Acrobat Reader, you can obtain it from the Adobe site.
Many Adobe Acrobat documents are quite large: their size is often measured in Megabytes (millions of bytes) rather than Kilobytes (thousands of bytes) as is the case with most HTML files. This can cause problems when you are on a slow connection. A common symptom is that nothing happens after you click on a link to an Adobe Acrobat file. The Adobe Acrobat window comes up, but the document remains blank. In such cases, your solution might be to download the file onto your hard drive and view or print it from there. The process is as follows: 

  • Hold your mouse over the link to the PDF file
  • Right click on the link
  • Choose Save Target As in the pop-up menu which appears
  • Select a location on your hard drive in the Save As dialog box
  • Click on the Save button
  • The file is now saved onto your hard drive. You can open this file just by double-clicking on its icon.

If you can view an Adobe Acrobat file, but have trouble printing it (receiving reports such as PostScript errors or out-of-memory errors), there are a number of things you can do. You can try to: 

  • save the file to your hard drive first (see above)
  • print it on a different printer, preferably one with more memory
  • print it one page at a time 

My username/password works with WebMail but I'm still getting "Authentication Failed"

The answer might be that your network account has been disabled. This would happen if:

  • You entered your username and password incorrectly several times. If you are staff, your password needs to be changed every 90 days. If it happens that you are trying to access remotely at the point when you should be prompted to change it, your account will be disabled.
  • To have your password reset:
    Students: - present your student ID card in person at the ISS Service Desk  in the Deirdre Thornton room
    Staff: - phone the ISS Service Desk 

I was able to sign in and use the database, but after a while it gave me a message that I had timed out

Many databases have a timeout feature that automatically logs you out of the database if you haven't interacted with it for a certain amount of time. You will need to return to the page where you originally clicked on the link for that database, and log in again. Note: time spent reading an article or composing a message to accompany citations you are mailing to someone does not count as time spent interacting with the database, and may trigger the timeout even though you are still "using" the database.

Questions or queries relating to library databases should be directed to the Library Information Desk or your Subject Librarian
