Problem: IE does not connect to URL

Problem: IE does not connect to URL
I have a private instance of webpagetest, latest version (2.2). I can submit a test, and URLBlast gets the job and starts the test with no problems. For each iteration of the test it opens up about:blank in IE, then tries to go to the URL under test, but after about ten seconds of not reaching the URL, IE is closed.

I was able to repeat the test using Chrome, and after about ten seconds Chrome complains that DNS did not return an address for the hostname.

If I open up IE and Chrome from the desktop and try to go to the URL, they both work fine.

The URLBlast log file looks like this....

RE: Problem: IE does not connect to URL
Can you capture a tcpdump of the failed test (checkbox in the advanced settings)?

Any chance that the LAN you are on uses a proxy (manual or automatic)?

Can you do a "tracert mainline.tripadvisor.com" from a command prompt?

Thanks,

-Pat

RE: Problem: IE does not connect to URL
1) I've done this - where does webpagetest put the tcpdump output?

2) No - no proxy

3)

Here is a heavily filtered version of the cap file that removed everything not related to the test itself:
.cap  filtered.cap (Size: 11.4 KB / Downloads: 130)

From the looks of it, DNS resolved correctly to 192.168.36.136 and the HTTP GET was issued correctly and the response started to come back but the test machine completely stopped responding to the server after the response started coming in.

Hard to tell if any of the response was actually processed but it looks a lot like what you'd expect to see if a firewall on the PC clamped down the session for some reason (otherwise I'd at least expect to see ACK's for the packets go back out).

Here is the actual text of the request:

Code:
GET / HTTP/1.1
Accept: image/gif, image/jpeg, image/pjpeg, image/pjpeg, application/x-shockwave-flash, application/x-ms-application, application/x-ms-xbap, application/vnd.ms-xpsdocument, application/xaml+xml, */*

Accept-Encoding: gzip, deflate
Host: mainline.tripadvisor.com
Connection: Keep-Alive

and the response:
