Symptoms

If you use the Diskeeper 1.0 from Diskeeper Corporation uninstall feature after you upgrade Windows NT 3.5 to 3.51 and restart your computer, you receive an entry point error in NTDLL.DLL and Windows NT hangs and becomes unbootable. 

NOTE: Diskeeper for Windows NT is a disk defragmentation program for Windows NT 3.5.

Cause

Diskeeper version 1.0 is not designed to run under Windows NT 3.51.

When you install Diskeeper on Windows NT 3.5, Diskeeper replaces the following Windows NT system files with its own versions of these files: NTDLL.DLL, NTOSKRNL.EXE, FASTFAT.SYS, and NTFS.SYS. If you use the Diskeeper uninstall feature after you upgrade to Windows NT 3.51, Diskeeper replaces the Windows NT 3.51 versions of these files with the Windows NT 3.5 versions. These do not work with Windows NT 3.51.

Resolution

Run the emergency repair disk (ERD) to recover your Windows NT 3.51 boot and system files. Do not run Diskeeper version 1.0 under Windows NT 3.51.
Diskeeper 1.01, which works with Windows NT 3.51, is no longer available from Diskeeper Corporation.
