I've been using this MS tool to test our user based web application by entering URLs with session IDs. I have 2 test accounts set up, with 2 tests. In each test the test user just hits two pages (i'm testing how long it takes those pages to load)

The first test account runs smoothly, and I get expected results.
BUT, for the second test account, all I get are Socket Connection errors. But if I manually type in the URL which I'm testing, I can reach the page with no problem.

So my question is, what does the Socket Connect error mean in the web application stress tool?

Socket Errors
Connect: 6723
Send: 0
Recv: 0
Timeouts: 0
