Not tracking visitors from secure network
I'm hoping someone might have some ideas as been wracking our brains over this for months. We are using analytics on our internal intranet. We have various groups of staff visiting the intranet from several different networks. It is tracking visitors from most of them fine, but there is one particular network that we are not receiving any visits from even though we KNOW that people are visiting it. The network is a secure network using IE6 and Firefox 31. We have no visits recorded from either of those browsers.
Does anyone have any ideas as to what could be blocking them? And whether we can do anything to resolve it or is it more likely it would it need to be done by the sysAdmin of the particular network?
