After spending the better portion of this week troubleshooting, I've concluded that the Virus Scanning application on all the district computers is a large detriment to MAPS. In simplistic terms, when TestTaker starts up, it is copying all of the student info and test questions from the server to a temporary location on the C: drive. this is a fairly large amount of data and can be slow when many computers are doing this all at once, without any delays. At the same time, our anti-virus application is doing what it is supposed to - scanning every single file that gets saved or copied to the hard drive. The natural drawback is that this also slows the loading process as each file pauses for a fraction of a second to be scanned. Eventually, the TestTaker either times out or believes that one of the files is corrupt and produces the error that you are all familiar with by now. The first solution I thought of was to remove the Virus Scan and this is what I've done at OMS in both labs. After all that, I thought of a better (i.e. easier) way to help this morning. I pushed a setting through the Application launcher this morning that will disable the service controlling the scanner. It will be/was pushed out to any computer that uses a MS/RC or EL student login today. after this setting is in place, a reboot is required for it to actually be in effect. Time for the payoff - to ensure that all machines are set to go Monday morning. Please make sure that any computers that will be used for testing gets logged in once today by a student user, then reboot, or just wait and shut down this afternoon. When they start on Monday, the scanner will be disabled and the tests will load correctly. This won't prevent 100% of the problems, but I think will help with a large majority of them. I expect there to be a few instances where the load still hits the time out period, but it will be due to too many loads running at the same time, instead of the Virus scanner. In this case, just go back to the student selection screen and try again until it loads. Finally, if you want to be sure the virus scanner is disabled, check the taskbar icon. Normally, it is the blue box with the "bouncing ball" running through. When disabled, the blue box will have the classic Red Circle with a line through it.Keep your fingers crossed!

MAP Testing- hopefully not the apocalypse
MAP testing starts Monday morning. Doug and Zach have been working on getting it running. Here is Doug's summary of the situation.
