Windows 2000 Repair Utility For Registry

A corrupt registry can generate a number of errors on your Windows 2000 system and can even make it unbootable. Chkreg.exe is a command-line Windows 2000 repair utility that helps you recover your Windows 2000 server from a corrupted registry. The utility supports Windows 2000, Windows 2000 SP2, and Windows 2000 SP3. It is recommended that you do not use Chkreg.exe with SBS 2003 because the tool has not been completely tested on it.

One of the other reasons behind registry problems in Windows 2000 is the size of the registry. In Windows NT and Window 2000, only 16 MB of memory is allocated for the boot up process. Therefore, you may start having startup problems as soon as the registry size exceeds 10 MB. Chkreg.exe helps you display the registry size to check if the registry size is creating problems with your 2000 system.

How to Use Chkreg.exe

You can download Chkreg.exe on a genuine Widows 2000 system from Microsoft.

The utility is then downloaded to six floppy disks and run on the system that is encountering registry problems. The utility tries to fix the registry of the faulty 2000 computer to enable it to start again.

Note: Depending on the type of problem, you may have some data loss when the registry is fixed.
