JSI Tip 0815. SP4 interferes with Workstation Power Management.

If you have Power Management on your NT 4, SP4 Workstation, chances are that it no longer functions.

With SP4, a Windows NT Server function writes a time stamp to the the hard drive approximately every 5 minutes in order to approximate system shutdown time in the event of improper shutdown.

Unfortuneatly, this feature is turned on by default, even on a workstation. To disable it, navigate to:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion

With the Current Version key selected, Add Key name Reliability (unless already present) with a Class of REG_DWORD. Select the Reliability sub-key and Add Value name TimeStampInterval as a type REG_DWORD and set the data value to 0.

You will need to restart your workstation.
