Hi all, I also have similar problems on two XP and one Vista. Starting the services give me a disk Icon in the explorer but with a white question mark on a red background (and the error associated message: W:\ refers to a location that is unavailable). I've used it the whole week-end on one system and last thursday and friday on the second one. Today they have the same behaviour: starting it, opening the page with the redirect (that ends-up with a page not found). I've moved the "Uniform Server" dir to almost everywhere but same result. I've turned off the antiviruses (McAfee on one and Kaspersky on the two other) and still the same problem ..... TIA, Al
