I have a W2k sp4 PC. When I try to run the KB835732 security update, upon reboot, I get a bluescreen with Stop 0x1E(0x5, 0x8041F898,0x0,0x30) ntoskrnl.exe error. I loaded the update, then replaced the ntoskrnl.exe file with the prior version, then ran the scan to verify that the PC does not have Sasser. With the old ntoskrnl.exe file in place, the PC boots fine. Any ideas
