RaveRod Hey thaNX for the info. We're running SP2 build2179 & prefer to stick with this RTM release, which is working well for us. The value @ offset ECEA = C0 (not C9). All other values are as you posted for 2180... ...sorry - found the answer here Is the manually applied registry value name "SFCDisable" or "SFCSetting"? thaNX
