OK, Kelsenellenelvian doesn't know what it is ( they are? ) for, and assumes I have a problem. Please forgive me in my frustration, but I swear before God that I am fluent in English and I asked exactly the question I intended. All of my google searches have been for naught. I have read through a hundred pages of posts at Microsoft support, Elder Geek, Minasi.com, Microsoft TechNet, eggheadcafe, wincert.net, and here. I'll be monitoring this thread as closely as possible, because I am very, very interested in the answer. Everybody knows how to fix it. Nobody seems to know what it's for.
