I am supporting a tester who does not seem to be able to access the Internet using the Test Studio application. He is using a dedicated domain test user account to logon to test studio and I have verified that this user can gain access to the internet via a browser, however when the tester tries to run a test with an IE browser it is as though he cannot gain access to the internet through our web appliance and he is getting 'page cannot be displayed' message.
I have looked for areas in the software where a web proxy could be configured but have found no setting for it. He is using version 2015.1
