Thanks Mark for the quick reply.... Actually, I went looking into event viewer and saw a couple of errors that didn't come up during installation. I tried installed (repairing /reinstalling) the Msg & Colaboration services, and all of a sudden came up with errors where the Installation was looking for files in the wrong place. Even if I pointed the installation to the correct location of the files that it could not see, it would still not recognize the file. Very strange indeed. I might need to find another installation disk???? Willy
