The client is a Citrix server. It's fine on every other of the 88 Citrix servers we have. DNS is fine (although I have tried using http://ipaddress<domain>.index.html and that gives the same result.
Firewalls are fine (I've done a telnet from the client to the qvs server on port 4750). I've tried it from standard client PCs (fine again). There is just one server that can't get past the 'Loading Content' stage. The 'faulty' client does indeed list this address as being one of IE's 'Local Intranet' sites.
The server is in a pair of Citrix servers for that site. One works perfectly and one doesn't. As far as I can tell they're configured the same. Same version of Java etc.. The only difference is that the 'faulty' server is running IE11. The working server is running IE9. However, we can connect successfully from other clients running IE11.
Can anyone suggest anything else? I'm running out of ideas. We have thousands of clients. What could it be about this one client that would give us this 'Loading Content' error? Thanks.
Regarding the second link - would this log-on-as-batch job permission be required on a machine that is connecting to the qlikview server via Internet Explorer? None of the other client machines (and there are literally thousands of them) are configured this way.
