Every 60 seconds, Windows Server 2003 polls for corrected hardware error conditions.
When the firmware also operates on the corrected error information, a conflict may exist.
If you want to disable the corrected machine check process:
1. Open a CMD.EXE window.
2. Type the following command and press Enter:
REG ADD "HKLM\SYSTEM\CurrentControlSet\Control\Session Manager" /V EnableCMC /T REG_DWORD /F /D 0
3. Shutdown and restart your server.
