Thanks very much for your advice. More and more research seems to be suggesting the time problrem. Now that we fixed an issue with the time, I think we just need to wait and see if the problem occours again on any other PC's. I just had hoped that when we fixed the time, the PC that is currently having these problems would start working again. Perhaps not!
