We have had our server site up for a year. In the last few months we republished a service and added a new service to our TOC. The updated service and new service show all layers to be active and to scale on the TOC (black check mark). Previously the check marks would stay greyed out until the layer actually became active. This feature no longer works. The layers that are in our site that we have not changed in the past year still show the scale dependency with the grey check mark and when the layer is up to scale, the check mark turns black. The scale dependency appears correct in the mxd, however, when the service is published and added to the config in flex, the layers show up as "active" at all times, even though they will not show up until they hit the set scale dependency we applied in the mxd. What would cause the scale depenedency check marks to stop functioning?
