How to reapply SQL 2000 SP4 to update all the 13 scripts

Due to any issue, you may want to rerun SQL 2000 SP4 upgrade.

SQL 2000 Service Packs are cumulative. But when you re-run SP4 it only updates 7 Scripts those are new with SP4. This could be useful when SQL Server is already on SP3 and due to some reason the SP3 installation had not updated all the scripts/files. Now when you apply SP4 on a Server that is already on SP3, SQL Server 2000 SP4 upgrade only updates and applies the new scripts/files. Hence it run runs only 7 SQL Scripts.

In a specific scenario, we will be unable to configure replication. The error is "The user already exist in the distribution database".  We have run the SP4 Upgrade, a couple of times.

The cause of the issue is that Due to some reason the SP3 installation had completed with errors and the sp_changedbowner procedure was not upgraded. The updated sp_changedbowner belongs to SP3. The only option is to dupe the SP4 setup as if the SQL Server was on RTM so that it would install/update all files and scripts.
