100% Processor Utilization on Windows Backup

100% Processor Utilization on Windows Backup

Here is an odd one for you. I was backing up my notebook today ahead of Dell’s replacing the mainboard. My notebook computer would not launch Ntbackup. The process spikes the cpu to 100% and then hangs. I let it sit as long as thirty minutes and the process never releases.

I did some research. See that this problem is fixed with Windows 2003 SP2 (which I have). Reinstall SP2. Reboot. Reapply latest hotfixes and reboot. Retry, same. Did the file actually get updated? Change directory to i386, which contains a slipstreamed SP2 version of Windows 2003. The file is exactly the same.

I run Filemon and open Ntbackup. See that it is getting stuck on website.zip. This is a malformed zip file that Shabbir sent me a few weeks ago. End task on Ntbackup. Delete the zip file and clear the trash. Re-open ntbackup. click the Backup tab. It works properly now. Got it!
