We have had some errors with SP4 regarding with it increasing the registry size. See below:
<Our dells have a promise PCI controller, it only leads to the latter that the update is making the registry file too large to be able to boot in conventional memory. Believe it or not, Wintel based pc's still only have 640K for Dos, and 16mb for windows at boot. Over this and the system
halts. So this would be a good reason to hold off on installing SP4 on any machines until they resolve this issue>
Anyone else see this issue when playing around with SP4?
