Good Day All;
When I tried doing this above process on my AD Domain the result was that the client machines would lock in 1-2 minutes. When I looked at the settings for Screen Saver they were greyed out as they should be and it had the 15 minute setting as it was done in the AD at 900 seconds. Does anyone know why this happened? Thank you for your help.
