Microsoft Security Updates from July 2018 Cause Errors
Posted by Brian Kleeman on 20 July 2018 11:15 AM

Updated July 23, 2018 (added specific Security Update codes for Server OSs).
 
Symptom:

After installing July 2018 Microsoft Security Updates the LMS no longer functions. Attempts to access it display the following or similar error in the web browser:
 
Microsoft VBScript runtime error '800a01a8'

Object required: ''

Cause:

Microsoft Security Updates released in July 2018, have broken COM component initialization given certain conditions.
 
Microsoft is aware of the problem with these updates and is actively working on a solution. Details can be found here.

Applies To:
 
Inquisiq LMS (all versions) running on the following operating systems (affected updates listed in parenthesis):
  • Windows Server 2008 (Security Updates: 4338422, 4338417)
  • Windows Server 2008 R2 (Security Updates: 4338423, 4338417, 4338420)
  • Windows Server 2012 (Security Updates: 4338416, 4338418, 4338419, 4338421)
  • Windows Server 2012 R2 (Security Updates: 4338424, 4338415, 4338419)
  • Windows Server 2016 (Security Update: 4338814)

A complete list of all effected updates can be found here


Resolution (Recommended):
 
Remove Microsoft Updates that are listed above:
  1. On your server, go to Control Panel > System and Security > Windows Update
  2. Click the "Installed Updates" link in the lower left corner of the window under "See Also".
  3. Find and select each Microsoft Update in the list and click "Uninstall".
  4. You may be required to reboot your server.

Additional Resolution:

Change the IIS Anonymous Authentication settings for the Inquisiq LMS website to "Application Pool Identity". This resolution is not recommended until we have a chance to fully test its ramifications. Also note that installing any Inquisiq LMS Upgrades will revert this setting, so you will have to perform these steps again after installing any LMS upgrades.

  1. In IIS, select the Inquisiq LMS website.
  2. Double-click the "Authentication" icon. 
  3. Click the "Anonymous Authentication" item; click "Edit..."
  4. Select the "Application pool identity" option and click "OK".
  5. You may need to restart IIS for settings to take effect.
