Component Services has stopped working

I have W2000 pro installed. Component Services use to work but now when I attempt to invoke it I get the following error message:

Component Services: mmc.exe - Application Error
The memory could not be read

Does anyone know how to re-install only Component Service...I really don't want to re-install the entire W2000 pro again.

Thanks

Resolved issue. 1) Run DTC setup from c:\winnt\system32 in windows explorer 2)Run reinstall windows components from software Prgram Install/Remove 3)Rebbot. Tested and works
