At IU, why am I having trouble accessing some services, and what can I do about it?

At Indiana University, if you are having trouble accessing a secure service, such as Oncourse, IU Webmail, CAS, or OneStart, check the following:

• Visit the IT Notices page. The trouble you are experiencing may be part of a larger but temporary system problem. System outages, downtimes, and maintenance are all listed here, along with information about when the relevant services will again be available.
  
  
• Be sure that you have properly entered your login information (i.e., your Network ID).
  
  
• Use the Passphrase Maintenance utility to synchronize your passphrases; see At IU, how do I change my Network ID passphrase?
  
  
• Some browser versions may cause access problems. Installing the most recent updates for your web browser may resolve the problem. You might also try using a different browser entirely (e.g., if you were using Internet Explorer, try Firefox). For information about browser requirements, see About OneStart and web browsers, About the Student Center in OneStart, To access Oncourse, which web browser should I use?, and Which web browsers should I use with various IU services?
  
  
• Some spyware and peer-to-peer file sharing software packages may cause errors when accessing Oncourse or IU Webmail.

  UITS recommends that you install and use Windows Defender to remove such spyware programs; see What is Windows Defender and how do I use it?

• Some security software packages as well as newer web browsers include a feature called pop-up blocking, which reduces the number of windows that open when browsing web sites. Pop-up blockers alter the JavaScript code of the web page before it is displayed in your web browser. If you have pop-up blocking enabled, and you experience oddities interacting with a web page, disable the pop-up blocker and reload the page.
