    Unfortunately I am a Jack Of All Code and Master of None....  This problem has surpassed my abilities and searches do not respond with anything close to my issue.

    I have coded a page that takes a source listbox that is populated with available options and a partner listbox to pass the selected options to.  I've stripped the page down to just the list boxes and manually entered items.  I am developing on a Windows 10 laptop, testing on a Windows 2008 R2 server, and deploying to a Windows 2012 R2 server.  The listbox renders correctly in development and testing.  When published to the production server it is drawn but it does not respond to clicks of the list items.

    I created a test site on the production server and the page worked as expected.  This test site was <servername>.<domainname>.com:1180.  I found that when I altered this test site to <alias hostname>.<domainname>.com:1180 the listbox failed again.  Thinking this may be a security issue in Windows 2012 I added the alias to the SETSPN list for the local machine.  This did not resolve the issue.

    Is this a security issue in Windows 2012?  I do have other Telerik controls working on this production server without issue.

    Thanks in advance for any help or support.

    This is awkward..  I have spent two days on this but 30 minutes after creating this post I found that my working applications do not use the Telerik script manager.  After replacing the script manager the problem seems to have been resolved.
