How can I reinstall the enterprise manager? (SQL SERVER 2000)

I can’t use the DTS editor because shows an error.

So, I want to reinstall the enterprise manager without uninstall the sql server 2000, Is that possible?

If the answer is yes, How can I do that?

I think that reinstalling only the Enterprise Manager the DTS editor can be fixed.

Sql Version: Sql Server 2000

SO: Windows 2003 Server

Tanks in advance
