Sorry about the unclear details. Inline SmoothWall so they were subject to normal filtering on a hidden "exams" SSID. I suppose technically they weren't 100% non domain devices as they were authenticated with domain accounts but they were vanilla windows with only surpass installed and computers were not members of the domain. I didn't have much faith in the software after my testing encountered numerous issues, especially with the AV software we run. With my previous experiences with exam software I wanted to have the simplest environment, as they often encounter problems. The students were under exam conditions so while this wasn't the optimal solution we concluded this would most likely be the most reliable way of running the test and we'd use the invigilators to keep an eye out for anything suspicious. These are very important to the students and school so making sure they were able to take the assessment trumped having a more secure environment. Starting the tests was a little slow but they got there after a bit of a wait so we were concerned their may have been a bandwidth issue our end but after looking at our bandwidth usage we were no where near full utilization (max of about 20%) of our 1 gbps connection so it was clearly it was a problem at their end. Here is the internet utilization over the 2 hour period of the exam.
If you want me details PM me and I can go into more detail.
