Curative Analysis: ‘Own IT’ for November 2018

The Curative Analysis team in IT is tasked with finding the causes of significant IT issues that affect campus. In this news update, we draw your attention to some of the problems being investigated or issues handled recently.

Blackboard Login Issues:  A security feature from the updated firmware on the external firewall caused the firewall to incorrectly block Blackboard authentication traffic.  This firmware was updated during the fall Data Center outage, and a basic security feature that has been enabled since we have had this firewall in place now appears to not be working correctly.  It has now started blocking authentication traffic for Blackboard.  We have rolled back the firewall firmware to prevent this issue from recurring.

Windows Computers:  An issue was discovered after a recent Windows Feature Update causing several computers running the Windows operating system to attempt to log in to the Azure AD domain instead of the WCU domain.  Clients can still log in to their computers by using wcu\ before the username (i.e. wcu\username) at which point a technician can unbind the computer from the Azure AD domain and rebind it to the correct WCU domain. IT staff are working with Microsoft to determine the cause of the issue.

Zoom:  Users who have a pre-existing Zoom account using their WCU email address are intermittently unable to login to Zoom using single-sign on (SSO). As a workaround, users can be directly invited through Zoom, and then SSO access works correctly after initial setup.  IT staff are working on a permanent resolution for this issue.

Outlook Login Prompt:  Several users are receiving a login prompt in Outlook repeatedly. Even when typing in their credentials, users continue to receive this prompt. Users can close the login window and continue to use their inbox normally.  Checking for Outlook updates and running them has fixed the issue for everyone.

Upper Campus Network:  Bad fiber on upper campus caused an interruption in network connectivity in November.  The networking team has installed a switch midway through the problem link to act as a repeater.  The fiber is expected to be replaced in December as work continues to prepare for the new upper campus residence hall.

ShareLink:  An update to the firmware for ShareLink in conference rooms is causing an issue with Extron audio transmissions.  IT staff are working with the vendor to obtain an update.  As a workaround, we are rolling back to firmware version 2.0.2.5 and adjusting the digital audio gain or attaching an audio cable.
