Based on my own experience (and now yours too, apparently), there is something basically incompatible with IE11 and the Juniper VPN connection functionality. I myself had this occur for three separate remote customer sites I connect with, and believe it is Java related (but I'm not sure). However with IE11 Network Connect wouldn't launch at all.
I can't recall now if I tried 'compatibility view' as a way to 'simulate back-level IE' to get around this, though I suspect I did and it still made no difference.
Anyway, the tech support help desks at all sites said 'they do not support IE11', and suggested I revert back to IE10 which I did.
Sure enough, Juniper VPN once again worked perfectly under IE10 on all three sites.
Doesn't make a serious difference to me which version of IE I'm using, since Firefox is my primary browser. I only use IE (and then IE10 at that) for customer VPN connection issues when required, including Citrix ERD sites as well as Juniper sites.
Sorry... we're both in the same boat here. IE10 is what's on my 'work machines'.

We have an issue where host checker is taking a long time to run and it is because our machines do not have internet access and cannot check.
