We have a problem on about 5% of machines which are set via group policy to use an automatic configuration script (from an HTTP source)
The issue is that when starting ie 8 the intranet page is displayed however when going to an external web site (which would needs to go via a proxy) the page times out. Pressing refresh and the page is displayed.
ie then works as expected.
Closing ie and opening it again and the problem returns. Most machines work fine
I am not sure how to start trouble shooting this
Any advice on how to trouble shoot this would be great.
