C000021A 0x00000000 (0x00000000 0x00000000) not 0x00000005

Trying to free an XP Pro Service Pack 3 machine from the grips of iemonster. Removed as much as I could then installed CA anti-spam to remove the rest. Rebooted after installing CA anti-spam and now cannot get by this stop error. Have tried every option within the “F8” startup menu. Any help here would be greatly appreciated.

Thanks,
James
