Random timeouts with TruClient IE? ...

Every so often (I tell the script in vugen for example to run 25 iterations) the script will fail with a timeout error. It looks as though the Web site is simply down or unavailable. But that’s definitely not the case. When this happens I can easily browse to the site with IE on the vugen machine or another machine.

If I kill the run in vugen and hit Play again it works fine, for a while. It’s almost like TC/VUGen simply forgets how to get to the URL? And we're not talking about any processing. it's a static landing page.

Any ideas? I'm intentionally using "Simulate a new user on each iteration."

Thanks in advance,
Chris
