A really weird issue has arisen on a 2012R2 Terminal server.
In IE or Chrome, when a PDF is downloaded, the file extension will be stripped from the name. (.exe and .zip files do not appear to suffer)
For example items on this page, beta.companieshouse.gov.uk/company/03452791/filing-history
Download from the site without the file extension on them and need to have it added manually.
This happens in both Chrome and IE11 but do not appear to happen at our other customers or even in our own office.
Second Issue is related to the same customer, in that on the same terminal server certain sites will not load in IE but will load perfectly in Chrome.
The following page is a PDF as well so it might be a related issue, when trying to load it in IE they get a "This page can't be displayed" This happens with other sites but I do not have a list of them at the moment.
http://goo.gl/fAhGE6 is the shortlink for it.
The weirder thing is that their other servers have no problem with this site and they all use the same server for DNS as well.
For opening PDF files we currently have Foxit Reader installed. Which has worked perfect over the past 2 years.
Can anyone think of a setting that might be causing it?
